Guide: The original "Smart Transportation Construction Practice and Development Trend" (see the end of the article for the source), this article selects the essence and structure part, with clear logic and complete content, providing a reference for the rapid formation of pre-sales solutions.
What is Smart Transportation
Intelligent Transportation System ITS (Intelligent Transportation System) is to effectively integrate and apply advanced information technology, data communication transmission technology, electronic sensor technology, control technology and computer technology to the transportation system, thereby improving the efficiency of the transportation system comprehensive application system.
Smart transportation is a traffic information service that integrates new technologies such as the Internet of Things, cloud computing, big data, and mobile Internet on the basis of intelligent transportation, and provides real-time traffic data by collecting traffic information.
Smart transportation uses a large number of data processing technologies such as data models and data mining to realize the system, real-time, interactive information exchange and extensive services of smart transportation.
The main goal of smart transportation construction
Main objectives: improve transportation efficiency, ensure traffic safety, alleviate traffic congestion, and reduce air pollution.
Smart transportation is an important construction content and entry point
Smart transportation covers data collection from bottom-level perception devices, data transmission, data governance, data sharing and exchange, and multi-dimensional display of upper-level data, automatic control based on big data and artificial intelligence. It is the best entry point for smart cities and the easiest See the construction content of the effect.
Smart Transportation Technology Architecture
2.1.2 Traffic Perception: Camera - Checkpoint System Checkpoint System
The bayonet is based on the camera set at the intersection of the main traffic hub, combined with intelligent instruments and software to realize the intelligent control of road traffic, such as the current traffic flow, vehicle counting on the section, vehicle Feature retrieval, and some illegal capture functions.
The bayonet is generally used as a system supervised by the road traffic department. The main functions are as follows:
1. Target image capture: capture the images of all targets passing through the bayonet.
2. Vehicle license plate recognition: recognize the license plate number of the vehicle from the captured target image.
3. Cross-section traffic flow: statistics of cross-section traffic flow
4. Cross-section speed: detection of cross-section speed.
5. Time occupancy rate: The time occupancy rate is calculated by analyzing the captured information.
6. Vehicle license plate detection: Repeated comparison of license plate information within a selected time period in a selected area.
2.1.3 Traffic perception: smart poles - there are many poles, urban resources are inefficient, and the appearance of the city is affected
Traditional facilities such as lighting poles, traffic signal poles, traffic sign poles, road signs, and electronic monitoring poles are set up in forests, resulting in repeated construction of various poles in the city, repeated excavation of road surfaces and reinstallation of pipelines; At the same time, it is a great waste of urban ground and space resources.
2.1.3 Traffic Perception: Smart Pole - Perception Basic Platform for Smart City Construction
2.2.1 Traffic Brain: Traffic Signal Control and Intersection Optimization Management
The main function of traffic signal control is to automatically adjust the timing scheme in the control area, balance the traffic flow operation in the road network, minimize the number of stops, delay time and environmental pollution, and give full play to the traffic benefits of the road system. Through the manual intervention of the command center, the traffic is forced to be evacuated.
It mainly has the following five functions:
2.2.2 Traffic Brain: Traffic Guidance System
2.3.2 Traffic application: smart parking - analyze parking data from urban parking big data to provide support for decision-making
Collect the urban parking data of each parking lot, obtain multi-dimensional data such as car owners, vehicles, parking lots, and vehicle trajectories, and perform data cleaning and processing to build city-level parking big data.
Use the big data of urban parking to draw a thermal map of urban parking space load, find out the areas where the supply of parking spaces is tight, and use parking guidance and other means to alleviate congestion.
Predict parking trends in advance, issue early warnings for areas with high parking loads, and guide people to travel by public transportation.
