"Green wave belt is a concept that has existed for a long time in the transportation industry. The daily interaction relies on its own long-term technical accumulation in big data and artificial intelligence. Surrounding scenes, road traffic direction, driving speed and other factors, use the algorithm to calculate the optimal signal control parameters, quickly form the urban green wave plan, and dynamically adjust it according to the real-time traffic flow and road conditions on the road surface. The impact on the surrounding traffic is as small as possible, In the case of maximizing the use of existing traffic infrastructure, the complexity of coordination and optimization of green wave information control is greatly reduced, allowing the traffic control department to schedule and manage road network traffic flow with a click of the mouse, and turning 'Photoshop' into 'Meituxiu' in seconds, At the same time, it helps the urban traffic management department to build a digital traffic management business management system at a very low cost, quickly improves the level of refinement and intelligence of urban road traffic signal control, and achieves a "hundred times efficiency" with a "hundred-one rate" to help build a traffic power. Create a safe, orderly, smooth and civilized road traffic environment for the people to travel.”
Special thanks to Hangzhou traffic police. Hangzhou is the first city where our Smart Green Wave has landed. It is also under the trust and professional guidance of the Hangzhou traffic police that we have truly polished this product and continued to optimize it. Since October last year, we have jointly created and strengthened the construction of green wave belts with the traffic police brigades of various districts in Hangzhou, changing the original long-distance green wave belt setting mode, taking 3-5 intersections as a group, turning lines into planes, and speeding up Reached about 20%. At present, there are more than 200 green wave belts in Hangzhou, with a mileage of more than 300 kilometers, all over the urban area of Hangzhou. In their daily travel, Hangzhou citizens have already enjoyed the convenience brought by the green wave belt without knowing it.
Recently, Fang Yi, the founder and CEO of Daily Interactive, accepted an exclusive interview with Ai Analysis, and systematically shared his views and successful practices on urban traffic congestion control.

Urban traffic congestion control is a worldwide and most prominent problem in urban diseases, daily interaction seeks new breakthroughs in solutions
Love analysis: The report of the 20th National Congress of the Communist Party of China proposes to speed up the construction of a transportation power and a digital China, and improve the level of urban governance. As the most prominent and important worldwide problem among "urban diseases", traffic congestion is very realistic and challenging. At present, what pain points do traffic control departments generally have in terms of optimizing urban road condition management and serving citizens' travel?
Fang Yi: The 20th National Congress of the Communist Party of China proposed to speed up the construction of a powerful transportation country and a digital China. The Ministry of Transport and the Ministry of Science and Technology also jointly issued the "Opinions on Accelerating the Construction of a Powerful Transportation Country Driven by Scientific and Technological Innovation" and "Medium and Long-term Development Plan for Scientific and Technological Innovation in the Transportation Sector" Outline (2021-2035)". The promulgation of national strategies and related policies provides a good policy environment for the development of our data intelligence field, and also points out the direction of development.
During the "14th Five-Year Plan" period, my country's economy will shift to high-quality development, and the total volume of passenger and cargo transportation will continue to grow. The main problems facing traffic management are poor traffic in urban core areas and insufficient coordination of smart transportation. According to official statistics, the number of cars in 70 cities in my country has exceeded 1 million. Traffic congestion is the most common, most frequent, most prominent, and most important worldwide problem among urban diseases. Its governance is very realistic and challenging. . Based on on-the-spot observations and exchanges with the industry, we found that the current traffic control departments generally have the following pain points in terms of optimizing urban road condition management and serving citizens' travel:
First of all, the number of cars and the number of drivers in my country's cities have increased sharply, the urban population has continued to increase, and the transportation facilities have gradually become more complex. However, the degree of digital construction of urban intersections and road sections is still not high, the coordination of smart transportation is insufficient, and the data sharing system has not yet been formed. On-line monitoring and analysis of road conditions is difficult, and the timing intelligence of single-point intersections is low. Many intersections often appear empty or congested.
At the same time, most of the traffic control departments are mainly based on manual experience, lack of big data support, the effect of manual adjustment of intersection signal light timing cannot be quickly and accurately verified, closed-loop iterative optimization is difficult to achieve, and lack of sufficient coordination between different intersections and regions makes it difficult to deal with The complex traffic conditions that change in real time in the entire area, and the unreasonable single-point green signal ratio setting will have a great impact on the traffic efficiency of the intersection.
At present, Australia's SCATS (Sydney Coordinated Adaptive Traffic System) and Europe's SCOOT (Split Cycle Offset Optimizing Technique) system are commonly used in many cities. Although their timing and self-adaptive capabilities are very powerful, data collection is done through coils on urban roads. Or geomagnetic induction. The ground induction equipment is often damaged and malfunctioned due to the adjustment of urban road planning and the influence of perennial heavy traffic flow. Moreover, the SCATS and SCOOT systems are not "smart" enough, and the timing personnel need "code-level" capabilities. Complicated code scripts are used for time allocation, and the threshold for use is high, and the system has no "memory ability" for repeated temporary adjustments by traffic police, and it is difficult to accumulate experience, forming "reuse", and cannot flexibly respond to rapidly changing urban traffic conditions.
Finally, the investment in transportation infrastructure in each city is huge, and a single intersection can easily cost hundreds of thousands. It is difficult to get through the data of different suppliers. The investment cost of "one game of chess" in the whole city and region is high, and the hardware investment is large but the actual benefit is relatively small. .
In view of the above situation and pain points, Daily Interaction hopes to use cutting-edge technology to help innovate traffic management concepts, management methods, and management models, and improve the modernization, informatization, and intelligence level of traffic governance. This year, Daily Interactive has created the "Digital Intelligence Green Wave" product (hereinafter referred to as "Digital Intelligence Green Wave") for the field of smart transportation. This product can help the traffic police department to efficiently complete the intelligent timing of signal lights and the intelligent coordination and optimization of green wave routes. , realize the digital construction and intelligent dispatching management of road network traffic flow, better serve citizens' travel, and improve the level of traffic management in various cities.
At the beginning of 2022, Wenzhou City, Zhejiang Province plans to build China (Wenzhou) Data Intelligence and Security Service Innovation Park (namely "ShuAn Port"). Traffic" happened to be released as scene 001. We hope that by relying on the establishment of Shuangang, we will make full use of our massive and fresh mobile Internet big data and capabilities, and deeply integrate multi-party dynamic data from traffic management departments, map service providers, and third-party data intelligence service providers for joint calculation and build A set of localized business systems provides traffic management means for traffic control departments, and implements intelligent application in the field of smart transportation.
Love analysis: Compared with the traffic lights of the traditional timing scheme and the green wave belt scheme of manual coordination, what innovations and breakthroughs does the "digital intelligence green wave" advocated by the daily interaction have in solving the above pain points of the traffic control department?
Fang Yi: The so-called green wave belt is not a new concept, but a concept that has existed for a long time in the transportation field. The starting time of the green light at each intersection passed by the traffic flow is adjusted accordingly to ensure that when the traffic flow arrives at each intersection, it just meets the "green light", thereby improving the overall traffic efficiency of the traffic line.
Our "Digital Intelligence Green Wave" product will use big data intelligence to analyze the comprehensive traffic flow at intersections, optimize the green signal ratio of a single point, improve the utilization efficiency of intersections under heavy traffic, and at the same time screen out traffic arteries suitable for building green wave belts For intersections, the optimal signal control parameters are calculated using algorithms based on factors such as cycle times, surrounding scenes, road traffic directions, and driving speeds, and green wave coordinated control is added to ensure that vehicles on regional arterial roads can Pass smoothly, thereby reducing delays and stops, achieving the "maximum one stop" goal.
The biggest feature of the daily interactive "Digital Intelligence Green Wave" product is to realize the access and connection of the data layer, and conduct data mining and analysis of traffic scenarios such as traffic flow distribution, signal control characteristics, intersections and road characteristics to provide traffic distribution. , green wave recommendation, green wave optimization and other service components, and then support specific operations such as intersection/road network visualization configuration, intersection coordination relationship research and judgment in the specific application of traffic management, so as to realize "data characterization, feature service, service application It allows the urban traffic control department to conduct real-time analysis, response and monitoring of road conditions, especially to facilitate the traffic police to quickly and dynamically adjust the timing of signal lights at intersections under their jurisdiction according to real-time road conditions.
Compared with the traditional timing scheme, the "Digital Intelligence Green Wave" product can be quickly optimized according to the traffic flow data on the road surface, instead of the "fixed" scheme under the traditional timing scheme, which has higher practicability and flexibility; Coordinated green wave solution, "Digital Smart Green Wave" product is supported by traffic flow data and intelligent algorithms, which greatly reduces the heavy dependence on expert experience, and the operation is simpler, without the need for front-line traffic police to master complex codes, only need to pass 1 After hours of simple training, the front-line traffic police can master the system proficiently. It can realize the one-key configuration of the green wave scheme, and can also fine-tune single intersections and road sections by dragging and dropping. At the same time, Digital Intelligence Green Wave can conduct overall coordinated management and control based on the entire region, avoiding the overall inefficiency of regional traffic caused by the lack of systematic thinking at each intersection and road section for local optimization.

The daily interactive "Digital Intelligence Green Wave" product helps urban traffic upgrade from "manual transmission" to "automatic transmission"
Love Analysis: What is the general working principle of the daily interactive "Digital Wisdom Green Wave" product? In this process, what core resources and technical capabilities have been mobilized by Daily Interaction to ensure the intelligence, efficiency and safety of "Digital Intelligence Green Wave" products?
Fang Yi: Our "digital intelligence green wave" product, combined with Internet big data, provides personalized green wave signal control solutions in different time periods, and regularly monitors green wave road sections, and makes decisions on green wave solutions that meet the requirements. , to realize the digitization and intelligent dispatching management of road network traffic flow. Specifically, it can be understood from the following aspects:
Figure 1: Schematic diagram of the daily interactive "Digital Intelligence Green Wave" program architecture
Our "Digital Intelligence Green Wave" product uses a big data joint computing platform as the underlying infrastructure to maximize the security of data circulation and computing. This is because, although the massive amount of daily interactive data is provided to the system at the statistical level in the green wave scenario, which fully complies with the requirements of relevant laws and regulations such as the "Personal Information Protection Law" and "Data Security Law", but it also needs to be integrated with the traffic control department Even third-party data, therefore, needs to enter the private network through the border and perform fusion calculations with the data in the private network to provide services for upper-layer applications. In order to ensure product and data security, all data is placed on the big data joint computing platform of State-owned Assets Holdings for joint computing to ensure that the original data can be entered but not out, counted but not recognized, usable but not owned, algorithms are transparent and easy to supervise, and computing is safe and efficient , which not only guarantees the security of data sharing and circulation for data providers, but also realizes more application value for data demanders.
In terms of basic capabilities, Data Intelligence Green Wave connects to rich data sources, and uses a powerful system within Daily Interaction - "DiOS Data Intelligent Operating System" for data governance and fusion calculations, and generates information and control plan recommendations. We use our own big data to perceive real-time traffic flow data on the road surface. At the same time, under the coordination of the traffic control department, we will also access the basic road network data (such as traffic lights, lane lines, etc.), traffic police business data, and infrastructure sensing data of the traffic control department. In the future, it may even be integrated with more third-party maps and data from travel service providers, so that the traffic control department can make more three-dimensional judgments on traffic flow and road conditions. So how do we manage and calculate such complex data from multiple sources? This will use the DiOS data intelligent operating system. DiOS can fully mobilize the company's digital modeling, security computing, visual intelligence, smart transportation and other related core capabilities, perform fusion calculations on the basis of data governance of all parties, and "scenario" various traffic data for analysis and mining Traffic flow characteristics, travel OD characteristics, etc. of each intersection, road section, area, etc., in order to generate corresponding signal control scheme suggestions, and provide simulation components to facilitate the simulation and prediction of the effects of different signal control schemes.
In terms of business application and empowerment, our digital intelligence green wave is connected with SCATS and other systems through API and RPA, so as to carry out real-time transmission and execution of information control solutions and support automatic distribution. At the same time, based on regional and road network traffic characteristic data, daily interaction provides functional modules such as road network manager, information control optimization, green wave platform, cockpit, and operation monitoring, which can sense, research and judge the road network, and implement information control measures Dynamic adjustment and optimization, dynamic closed-loop management of self-filtering maps, green wave design, plan delivery, effect prediction and optimization of the green wave plan; based on the above functional modules, the urban traffic management department can And other full-terminal access methods, easily realize three-dimensional business applications ranging from macro urban planning suggestions to medium and micro road network construction guidance, digital intelligence green wave services, etc.
It is worth mentioning that the Smart Green Wave can also carry out "one game of chess" overall coordination and system optimization for regional traffic. In order to prevent the green wave belt in a certain direction from destroying the traffic efficiency of the road in the cross direction, for example, when a horizontal road is made into a green wave belt, our "Digital Smart Green Wave" product supports a traffic light intersection as the center. All intersections in the area are aligned with it, so that the intersecting routes and directional roads can be made into green wave belts, and the overall optimization of the regional traffic "a game of chess" can be carried out. Of course, traffic is unpredictable, and traffic flow is constantly changing in real time. Therefore, Digital Intelligence Green Wave must have the ability to deal with emergencies and continuously optimize iteratively. In the actual traffic management process, it is unrealistic to pursue all intersections with green lights. Here, the traffic control department needs to make value judgments. In order to prevent the situation of "the head of the snake bites the tail of the snake", Shuzhi Green Wave also supports the "temporary plan". Once a certain intersection Or when a temporary emergency such as a traffic accident occurs on the road section, the control of the signal light can be quickly restored to the original state. After the temporary emergency is over, it can be restored to the green wave state, thereby eliminating the traffic pressure. In addition, Digital Smart Green Wave can also use technologies such as short-term traffic forecasting and variable lanes to do a good job in the intelligent iteration of the Green Wave solution and build a closed loop of urban traffic management business.
Finally, when it comes to the specific use level, one of the advantages of our digital intelligence green wave products is that they are easy to use. The horizontal axis is a road, and the vertical axis is the time axis. When the phase of the signal light on the left is selected, the phase of the signal light on the right can be automatically aligned with one key. Through this relative alignment, the regional green wave zone plan can be quickly realized. With the assistance of the machine , let the difficult "photoshop" become "beautiful pictures" in seconds, greatly reduce the complexity of green wave signal control coordination and optimization, and allow traffic control departments to dispatch and manage road network traffic flow with a click of a mouse.
Love Analysis: In which aspects are the core values of the "Digital Intelligence Green Wave" product reflected in urban traffic management and people's livelihood? What kind of cities and road sections is it mainly suitable for?
Fang Yi: As you can see from the working principle above, our "Digital Intelligence Green Wave" product is based on the fusion calculation of big data on the Internet, and builds an urban green wave belt at a very low cost, helping urban traffic management departments to build digital traffic management business management system, perceive and analyze road profiles in real time, and give rationalized construction suggestions, rapidly improve the level of refinement and intelligence of urban road traffic signal control, and create a safe, orderly, smooth and civilized road traffic environment for people to travel.
It is worth mentioning that our "Digital Intelligence Green Wave" product will never waste any sensor, but will maximize the utilization of existing existing facilities , gather data together, and realize "cross-domain data fusion" Provide mutual authentication for urban traffic authorities. For example, in case of some extreme situations where the daily interactive traffic flow data changes rapidly, the traffic control department can use its own data to calibrate the daily interactive traffic flow data; Reasonable traffic facility data, and then to complement it.
Figure 2: The main advantages of the daily interactive "Digital Intelligence Green Wave" product
From the perspective of the scope of application, as long as the road section has realized online control, there will be an application basis for "digital intelligence green wave". At the same time, the daily interactive "Digital Intelligence Green Wave" product has its own set of metrics, such as the repetition rate of the number of vehicles entering and exiting a certain intersection, which needs to meet a certain indicator. Make a comprehensive judgment on the location and surrounding facilities. For example, we found that a section of road is equivalent to a tunnel, and the repetition rate of vehicles entering and exiting is very high. Then we consider this section of road to be a commuter road and suitable for green wave belt.
Love Analysis: It is understood that the daily interactive "Digital Intelligence Green Wave" product has been launched in Hangzhou, Wenzhou, Huzhou and other cities, and has received good feedback. Then, can you systematically introduce the company's construction ideas when helping urban traffic management departments implement the "Digital Intelligence Green Wave" project?
Fang Yi: Generally speaking, the construction idea of our Digital Intelligence Green Wave project can be divided into the following steps to realize a closed loop from concept communication, diagnosis, design planning to scheme optimization and solidification.
The first is the concept report. We will first present our understanding of urban traffic management, fully discuss with the traffic management department, and promote the two parties to reach an agreement on the concept; then, we will clarify the daily interaction based on the connection of the underlying data, and the use of intelligent algorithms to empower the front-end business The idea, emphasizing the user experience of traffic control departments, especially the front-line traffic police, has changed from the traditional thinking mode in the field of industrial control to the thinking mode of the Internet facing the C-end, improving the ease of use of the front-end, and without changing any original urban traffic construction plans. It can be done at very low cost.
The second step is to start planning and designing. The daily interactive "Digital Intelligence Green Wave" product uses the big data of the mobile Internet, the data of the traffic police department and the map service provider to automatically calculate and generate roads suitable for green wave construction in the city, and supports the construction of recommended green wave road sections. Manual intervention can be added, deleted or modified according to the actual situation. For example, in the Hangzhou Green Wave Belt project, based on our own measurement standards for green wave belts, we identified more than 700 kilometers of roads in Hangzhou that are suitable for building green wave belts, and submitted their distribution maps to the Hangzhou traffic management department for review and discussion.
Next is to configure the green wave. Digital Smart Green Wave can combine road network data and corresponding road sections, vehicle speed and traffic data at intersections to intelligently recommend a batch of road sections that are most suitable for building green wave belts, and calculate detailed green wave configuration plans to assist in the final green wave belt construction. decision making. The traffic police department can select specific road sections to experience the effect of the "green wave plan" based on our recommendation results. Then, we use the visual intersection manager to realize the comprehensive entry and visual display of green wave construction information such as signal infrastructure, channelization, and traffic flow; at the same time, the road network manager will integrate information such as road section length, historical speed, and road section characteristics to generate intelligent recommended speeds , to provide speed guidance for the green wave scheme design and ensure the green wave effect.
The next step is to divide the time period and plan design. Speaking of this, we have to mention the great advantage of our Shuzhi Green Wave products, which are easy to use. Digital Intelligence Green Wave supports the quick adjustment and optimization of the green wave belt by simply dragging and dropping on the time-distance map. (weekdays, weekends), etc., carry out personalized adjustments to the green wave belt, design multiple green wave schemes for specific intersections and road sections, and select the optimal green wave scheme based on the monitoring data and control experience of the traffic control department for specific road sections .
Single-point optimization is also valuable. In this link, we can combine intersection traffic data, intersection characteristic data, and intersection information control data to accurately optimize the single-point information control schemes of all intersections in the area to produce single-point recommended timing schemes divided by time periods. It can be issued automatically or manually, or can be issued to the signal light control system after manual intervention on the single-point recommended timing scheme.
Finally, it came to the trial run and program optimization and solidification links. We will assist the traffic control department to carry out partial or comprehensive trial operation of the overall and single-point optimized green wave plan on selected road sections, and conduct real-time operation monitoring of the effect of the plan. After optimization, it will be submitted to the urban traffic control department for confirmation, so as to realize the solidification of the green wave scheme for different intersections and different time periods.
Figure 3: Ideas for building a daily interactive intelligent green wave belt
In addition, from the perspective of specific service methods, the construction process of the daily interactive "Digital Intelligence Green Wave" project includes four major steps: pilot mode, platform deployment, product use training, and product optimization and upgrading. During the pilot period, daily interaction can provide some The green wave belt construction of the selected road section and the corresponding effect are promised, and free training and free iterative upgrade services for products during the maintenance period are provided.
Love Analysis: Can urban traffic be graded with reference to autonomous driving? What is the significance of this in helping smart city governance upgrade?
Fang Yi: Just as automatic driving can be divided into five levels according to the degree of autonomy "from fully manual to fully automated", we believe that the degree of digital and intelligent governance of urban traffic can also be determined according to the degree of intelligence of the control of signal lights at each intersection in the city. Grading, so we put forward the concept of "smart transportation 6L" classification.
Figure 4: Daily interaction "smart transportation 6L" grading concept
Level L1 means that there are signal lights at the intersection for basic traffic control. Level L2 means that the intersection signal lights are connected to the Internet, and the traffic police can issue commands remotely for single-point control. L3 level is based on L2, through the radar, camera, geomagnetic and other equipment installed at the intersection, as well as Internet big data, it can perceive the digital information such as the length of the queue at the intersection and the speed of the vehicle. The L4 level can analyze and model the data uploaded at the intersection to form a dynamic and data-guided closed-loop control. The L5 level is based on the L4 level to realize the intelligent coordination of multiple intersections, such as the construction of the "digital intelligence green wave belt". L6 level is to realize road intelligent management and control, that is, based on data modeling and analysis of regional road characteristics such as governments, business districts, and schools, it can realize fine coordination and control of multiple intersections, and comprehensively improve the functionality of regional roads.
The development process and scale of cities in my country vary greatly, and the progress of investment in transportation infrastructure varies widely. Even in some relatively developed cities in the south, a large number of signal lights in the cities may still be single-point-level and have not been connected to the Internet. Through the "smart transportation 6L" classification concept, daily interaction with local traffic control departments can be based on the same set of language and measurement system to help cities find the specific coordinates of different intersections and road sections, combined with the urban traffic construction plan and budget of the year , communicating targeted upgrade plans for different intersections and road sections, such as upgrading from L1 to L2, or directly upgrading to L3. At the same time, based on the agreed upgrade path, daily interactions can be completed within a certain period of time. The intelligent upgrade of urban transportation facilities on roads and roads, in conjunction with the flexible arrangement of the upgrade progress of each city, greatly reduces the pressure on fiscal expenditures in each year, making the intelligent upgrade of urban transportation visible, controllable, and low-cost. It is expected that the daily interactive "Digital Intelligence Green Wave" product will first be centered in the Yangtze River Delta, and then spread to the whole country.

Daily Interaction uses the core capabilities of data intelligence to deeply empower domestic large-scale transportation intelligence
Love Analysis: What kind of plans does Daily Interaction have in terms of digitalization and smart upgrades in the field of mass transportation in the future?
Fang Yi: In the field of mass transportation, we mainly have the following two plans:
In terms of urban transportation, as mentioned earlier, daily interaction will use big data to achieve initial intelligence in urban transportation. Currently, it is the "Digital Intelligence Green Wave" program. In the future, daily interaction will be closed-looped in a more refined way through the Wi-Fi sensing system or other new road condition sensing systems, coupled with big data, which will greatly reduce urban The construction cost of transportation intelligence.
In terms of high-speed transportation, Daily Interaction is currently in-depth cooperation with Zhejiang Gaoxin Technology Co., Ltd., a subsidiary of Zhejiang Provincial Communications Investment, to help it further deepen the expressway information business with the DiOS data intelligent operating system; at the same time, Daily Interaction also uses With its own technical capabilities, it has created an early warning system for abnormal situations on expressways, and actively participated in the governance of abnormal situations such as spilled objects on expressways. Specifically, we use the high-speed "gantry" ETC data to calculate the instantaneous speed of each vehicle's entry and exit and the speed of the interval between the two gantry, and according to the speed and traffic flow changes between the gantry, combined with the highway camera , to quickly discover problems on specific sections of the expressway and give timely warnings to reduce the risk of expressway accidents. At present, the early warning system for expressway abnormalities has been able to detect abnormal road sections in about one and a half to two minutes, and inform the high-speed traffic police two to ten minutes before the accident so that they can reach the abnormal road section in advance and quickly. deal with. In the future, Daily Interaction will further explore the governance scenarios of high-speed traffic, and make continuous efforts to improve the informatization of expressways and reduce the accident rate of expressways.
Love Analysis: Do you have any other views on road network digitization and urban traffic management that you want to share?
Fang Yi: There is a new trend in traffic management now that is to apply radar and video, but the investment cost and edge computing cost of this solution are relatively high. In recent years, our domestic computing power resources have been greatly improved, but computing power is limited after all, and the rational use of computing power resources has become the key to reducing costs and increasing efficiency. I think that many vehicles, especially new energy vehicles, are constantly emitting various wireless signals such as Bluetooth and Wi-Fi. If the traffic management department builds perception based on wireless signals above the ground instead of underground The difficulty and cost of managing traffic by means of equipment will be much lower, and it will become a new paradigm.
"Digital Wisdom Green Wave" is the result of daily interaction and innovation oriented to the needs of people's livelihood. As the country accelerates the general trend of building a transportation power, a network power, and a digital China, it is just the right time for us to walk on the road of data intelligence. We hope that data intelligence will drive more social changes in the future.
