Regarding the Guangzhou Intelligent Transportation System GZ-ITS (GuangZhouintelligenttransportationsystem), its planning and implementation work has achieved some important results in the field of Asian Games traffic vehicle management, which makes the space road network coordinated with people, vehicles and other transportation tools, greatly improving The modern level of Guangzhou’s traffic operation management has effectively reduced traffic load and environmental pollution, ensured the traffic safety of the Asian Games, and improved the transportation efficiency of the traffic road network.
1. Analysis of the Asian Games’ characteristic vehicles and intelligent Asian Games traffic conditions
For the 2010 Asian Games, intelligent traffic security is particularly necessary. The remediation of various electric vehicles and motor vehicles and the traffic control during competitions have become an important part of the overall requirements of the Asian Games traffic security. Regarding the tasks of the construction of the intelligent transportation system GZ-ITS, the responsibilities of the road traffic management science and technology department are clarified, and they are responsible for organizing the construction, transformation, improvement and maintenance of the urban intelligent transportation management command system and its Asian Games expansion project, as well as the timely application of intelligent transportation technology. , Do a good job in the security of traffic facilities for the traffic police during the Asian Games, coordinate the standardization of various traffic signs, formulate road traffic planning and traffic organization plans with other departments, and supervise and follow up on the Asian Games City, competition venues, and surrounding municipal road traffic The construction and transformation of infrastructure, including temporary parking lots and traffic monitoring systems, participate in the review of the implementation of traffic management and organization plans in the jurisdiction in a timely manner, and carry out special traffic rectification actions including “five types of vehicles”. Guangzhou is one of the important economic and cultural centers of the country. Its transportation technology construction and intelligent transportation development not only play a demonstrative role in the Pearl River Delta region, but also have demonstrative significance for the central cities of the province and even the entire country. To this end, the expansion of intelligent transportation facilities in the construction and guarantee of the Asian Games has been added, and a dedicated information platform has been established to ensure the intelligent and efficient special rectification of electric vehicles and motor vehicles and the intelligent and efficient traffic control during the game, so that the Asian Games can be held smoothly.
For the Asian Games venues and road traffic monitoring system, it mainly includes traffic engineering, traffic organization and traffic signals, traffic control, monitoring and communication pipelines, and for the Asian Games City and the internal roads of the venues, the connections with external municipal roads, parking lots and other traffic projects Scientific design was carried out; for the layout of internal road traffic organization, import and export, garage entrance and exit, security checkpoints, combined with the surrounding urban road traffic organization, coordinated connection with municipal roads, and considered the “five types of vehicles” factors in the Asian Games security requirements , Avoid opening too many entrances and exits on main roads, reduce the entrances and exits of arterial roads, and make full use of the traffic flow of vehicles in the internal road organization site; for the Asian Games security temporary facilities need to occupy green land, use public green space to set up parking lots, and the import and export of vehicles The design should meet the needs of Asian Games security and competition traffic organization. The establishment of temporary vehicle import and export on the road green belt meets the needs of Asian Games security and competition traffic organization; the road greening should be coordinated with traffic safety facilities such as traffic signs and lights. Avoid obstructing the sight of drivers from observing traffic safety facilities, and design and install necessary monitoring facilities and electronic tag reading cards at important road sections and intersections to predict traffic control of characteristic vehicles; for internal traffic in the stadium, ensure that the security is closed during the game Lines, security check channels, all personnel and vehicles need vouchers or tickets to enter the security enclosed area. The front yard and back yard are set up in the security closed line according to the security requirements. The general audience is restricted to the front yard. The back yard should be set up in the direction of the rostrum of the stadium. It is the activities of athletes, referees, officials and staff members of the OCA family. In the special area, the entrances and exits of the front and rear courtyards shall be separated, and the traffic flow lines of the front and rear courtyards shall not cross.
There are sufficient buffers for people and vehicles at the security checkpoints on the security line, and spectator distribution squares are set up to ensure that waiting for inspections and vehicles do not gather and queue on main roads, and do not affect the entry and exit of vehicles and normal traffic on the way. A buffer zone and a waiting vehicle parking area are set up at the vehicle security checkpoint to prevent vehicles waiting to be checked from blocking the surrounding road traffic, and VIP vehicles are reserved for inspection-free channels.
The venues shall be equipped with special channels for VIP guards, entrances and exits, and parking areas. The VIP channels for athletes, referees and officials shall not run through the waiting area for spectators.
The design of the approach flow line meets the security requirements, and the setting of security checkpoints fully considers the needs of road traffic organization, and vehicles waiting for inspection should not affect the normal traffic on municipal roads. The internal personnel circulation of the site should be combined with the external traffic circulation, and the external traffic circulation should be distinguished by combining the front and rear courtyards.
The roads in the site should comply with the road design specifications, and the design of safety technical indicators such as the horizontal and vertical slope, linearity, and curve radius of the road should also comply with the corresponding specifications. For the traffic road intersections and sections in the venue, the necessary intelligent monitoring facilities should also be designed and installed , To identify and characterize vehicles; the application of intelligent Asian Games traffic monitoring facilities, for the traffic control and command system to achieve the signal control of most intersections, combined with the construction of the inner ring line and subway, the city’s traffic management departments, to establish the urban backbone optical fiber network and the degree of intelligence The high spatial road network traffic command center uses information technology and urban traffic electronic maps to accurately publish traffic management information such as the traffic status of the spatial road network and the deployment of police forces in real time. It also integrates the Guangzhou traffic management data warehouse and auxiliary decision-making system to realize the Asian Games road The coordinated command and intelligent and efficient operation and management of the traffic area can monitor the traffic control section of the passenger flow of various characteristic vehicles.
2. Analysis of the characteristic management status of Asian Games traffic control vehicles
In recent years, the average monthly increase of motor vehicles in Guangzhou is more than 25,000, and the average annual increase is more than 300,000. In addition, the rapid development of urban rail transit, taxis, buses and BRT has brought many conveniences to citizens and is an important foundation for the successful hosting of the Asian Games. However, the requirements for road traffic science and technology management are getting higher and higher. Intelligent and information management have become more important. Six goals have been basically achieved to make Guangzhou’s road traffic management modernization reach the domestic advanced level: establish a fast and efficient traffic management command and dispatch system Improve the scientific and technological content of traffic management; provide multi-channel and rich traffic information services; establish an efficient information sharing basic platform; realize information sharing and collaboration with other government departments; provide comprehensive, accurate and timely decision-making data. At present, the roads are not only motor vehicles with vehicle identification plates, but also millions of five types of vehicles, including electric tricycles, electric bicycles, motorcycles, disabled vehicles, and modified scrapped vehicles. Traffic control vehicles including the “five types of vehicles” are characterized, that is, electric and motor vehicles are loaded with RFID chips, and the identity card information of individual drivers or small groups is stored for comparison and verification of road traffic, social security, etc. Real-time management and predictive traffic control are an important part of the Asian Games traffic security application.
3. Analysis of the application status of smart Asian Games traffic video surveillance
The city’s intelligent traffic management command system (“GZ-ITMS”) is the core body of information technology for the Asian Games security. Based on computer communication networks and intelligent command and control management, it has built an intelligent road traffic integrating high-tech applications. Management system, in order to improve the operation order of the road network, increase the effective utilization rate and capacity of the road, reduce the degree of traffic congestion, the frequency of accidents, and the extended travel time caused by traffic congestion and accidents, reduce exhaust emissions, etc., to achieve road traffic management Intelligentization, expansion of the command center and the monitoring system capacity of each sub-control center, extending the storage time of video signals, optimizing system functions, making remote management, hierarchical management, and multi-user management functions advanced, reliable, clear, complete, and efficient.
Related content is designed for the intelligent Asian Games monitoring and characteristic vehicle: when the system users call network resources, their video trunk allocation is random, and users have uncertainty about the video trunk seizure; different users in the system have no priority when calling network resources The difference between the user and the video trunk line cannot be associated, resulting in the phenomenon that the current user viewing the monitor image including the “five types of vehicles” may be switched away due to the preemption of the same channel by other users; the existing system realizes the user in the intelligent The traffic management command center carries out the remote configuration function of the central host, which needs to be extended to the entire monitoring star network to achieve dual data channel redundant backup networking, which is lacking in system disaster recovery; based on the existing system hardware and software architecture , The video input and output capacity is limited, which fails to meet the current safe city environment and Guangzhou traffic management needs for closed-circuit television monitoring points. To this end, to ensure the timely and normal operation of information-based vehicle facilities for intelligent Asian Games traffic monitoring features, the main countermeasures proposed are: adopt a time matrix process to manage the monitoring facility strategy, and indicate the working process of the monitoring equipment, the road monitoring link, and the working hours of each link. The total operating cycle, using the time matrix process, can conduct monitoring equipment action-time research on each link of the process, which is conducive to timely control of the entire process of monitoring equipment work, and accurately maps the monitoring status of the characteristic vehicle at a certain time. Improve the efficiency of monitoring applications.
According to the actual application urgency of monitoring information of different road sections, intersections, ramps, roundabouts, high speeds, etc., level layers are classified according to basic data, and police information is associated with police information to reasonably deploy and control police force, and public security video surveillance is associated to achieve integrated prevention and control Relevance to population information to find people by address, to counter-terrorism information for anti-terrorism early warning and urban emergency management, to be associated with police station systems to detect incidents in time, to be associated with traffic guidance information for safe and clear roads, to associate all kinds of related information, which is smart The Asian Games traffic decision-making department provides timely information services for characteristic vehicles. The application of intelligent traffic management and radio frequency identification RFID technology has effectively promoted the in-depth development and application of Asian Games traffic video surveillance, realizing intelligent video analysis, video monitoring point linkage, video analysis early warning or alarm, license plate recognition and detection, and vehicle license plate number characteristics Recognition, traffic flow statistics and automatic detection of road conditions, etc., in the handling of traffic accidents, traffic violation management, motor vehicle registration and driver’s license management, and management of temporary license plates during the Asian Games, as well as monitoring, real-time control, and real-time monitoring for the Asian Games security commanders. Scheduling played a positive and important role.
