Preface
With the development and change of the information age, the smart city presented on the screen has slowly appeared in real life, which greatly facilitates daily management and maintenance. In the context of smart cities , the smart traffic monitoring visualization system is an important part of it. Through the series connection of road monitoring, the management and control of a smart city is derived. In the maintenance of numerous data, real-time data, equipment status and video Monitoring is extremely important. Among them, video surveillance has always been the main part, and in the form of the Internet and the Internet of Things, "China Skynet" came into being. This is actually a city surveillance system, but it is not a device with only one camera. Instead, there are 170 million surveillance cameras, and another 400 million cameras will be installed in the next three years.
As the artery of urban development, transportation is closely related to people's daily life. Under the influence of this series of supervision, it has become a "public security video surveillance system", which is related to people's daily safety and security management.
The main modes of urban transportation are reflected in urban roads, public transportation, rail transportation and other facilities. However, with the acceleration of urbanization and the promotion of economic and social development, the number of motor vehicles has increased rapidly, and urban transportation problems have become increasingly serious. In the face of this situation, in order to alleviate the various problems of urban traffic, various solutions have been adopted, such as the construction of a series of signal lamp control, intersection bayonet monitoring, video surveillance and other methods of system maintenance, which have a certain degree of effect. , But each system independently solves its corresponding problems, unable to comprehensively control the overall traffic situation, and the management system that realizes urbanized smart transportation can deal with this problem well.
Between 2D configuration and 3D configuration, the HT for Web product of Hightopo (hereinafter referred to as HT) has a wealth of configuration options. This article will introduce how to use HT's rich 2/3D configuration to build one Solutions for intersection monitoring systems.
This article will introduce the realization process of the intelligent traffic visual monitoring system from the following aspects:
1. Vehicle generation and operation under the control of traffic lights;
2. Camera simulation and real scene monitoring;
3. Real-time data and maintenance of intersection monitoring information;
Interface introduction and effect preview
In the intelligent traffic monitoring system, the scene of real-time vehicle driving under the control of realistic traffic lights is presented. With a controllable weather environment switching panel, it can simulate the operation status of intersections in various weather; it also realizes the monitoring of intersection cameras Status, click on each camera at the intersection to view the real-time operation of the intersection within the monitoring range of this camera, providing the switch between simulation and real state; secondly, a lot of real-time data monitoring panels have been added to connect real interface data to real-time intersection monitoring The maximum efficiency of

System analysis
Through the combination of rich 2D configuration and 3D configuration, HT has sorted out many solutions on the industrial Internet. In the context of the promotion of smart cities, the visual decision-making system of smart traffic management systems is also an extremely important part. And in the monitoring of intersections, facing the large-screen environment of the traffic management smart center, the HT for Web product lightweight HTML5/WebGL modeling solution can be used in the three-dimensional scene to achieve rapid modeling, lightweight runtime, and even mobile terminal browsers. Good effects of 3D visualization operation and maintenance; the vector icon on the 2D drawing will not be distorted after zooming in, and it supports display scenarios such as large screens, multiple screens, and super-large resolutions.
1. Comprehensive situation monitoring
integrates geographic information system, video surveillance system, and traffic management department business system data, comprehensive monitoring of traffic conditions, vehicle flow, accident handling reports and other elements, and supports clicking to view specific police forces, maneuvering targets, traffic incidents, Detailed information such as surveillance video helps managers grasp the overall traffic situation in real time.
2. Monitoring of basic transportation resources
Support the monitoring and visual management of information such as the quantity, spatial location distribution, and real-time status of basic traffic resources such as cameras, traffic detection equipment, traffic lights, etc., support detailed information query of equipment, support alarming of equipment that is not working properly, and strengthen managers The monitoring and perception of equipment status improves the operation and maintenance management efficiency of transportation infrastructure.
3. Video inspection monitoring
supports the integrated front-end video inspection system, which effectively combines video intelligent analysis, intelligent positioning, and intelligent research and judgment technology to visually monitor road congestion points, hidden danger points, accident points, etc., to achieve abnormal events Real-time alarm, fast display, and intelligent access to surveillance videos around abnormal points can effectively improve the efficiency of receiving and handling alarms.
4. Intersection signal light monitoring
supports the integration of intersection signal lights, video surveillance and other system data, real-time monitoring of intersection traffic flow, speed, vehicle and road abnormal events, signal light status and other information, and can be combined with professional model algorithms to compare the best history Traffic speed and optimal traffic volume, visually analyze and judge the traffic situation at intersections, provide scientific decision-making basis for signal timing optimization and intersection traffic organization optimization, and effectively improve traffic operation efficiency.
5. Analysis of violations of laws and regulations
Fully integrate the existing data resources of the traffic control department, provide a variety of visual analysis and interactive methods, visualize serial and parallel analysis of massive historical violations of laws and regulations case data, deeply explore the temporal and spatial distribution of cases, and analyze the causes for the traffic control department , Active defense and other business applications provide support.
to sum up
Urban brains are being fired up, traffic light control to solve the problem of congestion is only the tip of the iceberg of smart transportation. Under normal conditions, monitoring, supervision, analysis and judgment are the powerful guarantee that traffic managers can really plan their strategies, and these are inseparable from making traffic data visible Sensible "smart traffic visualized decision-making platform".
Through the loading of real-time data, the state of the intersection can be reflected in an effective and timely manner, so that the previously scattered systems are connected in series to form a complete intelligent transportation system, and under this system, many roads are monitored in series. This is actually It is the epitome of a smart city, and based on past experience accumulation, HT has also completed a complete smart city system solution, which connects many city data and facility construction records, which can combine many functions The system performs real-time data monitoring and display: HT Smart City
