Article Summary
- Project Background and Policy Requirements The Shandong Provincial Government document emphasizes road traffic safety, and the report of the 19th National Congress of the Communist Party of China proposes the strategy of building a "transportation power". As a key support area during the "13th Five-Year Plan" period, intelligent transportation is of great significance to alleviate urban traffic problems and improve the level of traffic management services.
- Necessity of project construction Urban traffic problems are prominent, including traffic congestion, reduced vehicle speed, and reduced traffic efficiency. Motor vehicles are growing much faster than road construction, leading to worsening traffic conditions. The construction of intelligent transportation will help improve the environment, save energy, and improve the level of traffic management services.
- The overall construction goal is to improve the traffic network capacity, reduce traffic congestion and accidents, realize scientific and intelligent traffic management, improve the level of traffic information services, and facilitate public travel through the rational organization of traffic flow, improve the traffic information management system.
- Construction ideas include illegal management, order control, command and dispatch, analysis and judgment, and travel services. Front-end capture and back-end intelligent analysis are used to coordinate traffic flow, realize pre-planned command and dispatch of resources, and analyze and judge traffic behavior based on cloud technology.
- System architecture Build "one platform, two centers, and six types of applications" to integrate transportation resources, alleviate urban congestion, ensure traffic safety, orderliness and smoothness, improve the level of traffic management technology, and reduce urban traffic environmental pollution.
- Six types of applications introduce in detail the applications of motor vehicle violation perception, traffic incident perception, key vehicle control, key driver precision control model and traffic situation analysis, including accurate identification, comprehensive scene coverage, real-time analysis and comparison, etc.
- The detailed architecture of the system describes the system architecture that integrates transportation resources, improves the travel experience, and improves the level of traffic management technology through the construction of one platform, two centers, and six types of applications.
- The traffic big data platform consists of business platform, big data visualization, traffic facility operation and maintenance, people and vehicle control, traffic congestion mitigation, real-world combat command, macro simulation, micro simulation, big data congestion mitigation platform and other components.
- Transportation Big Data Platform Architecture This paper introduces the platform architectures of scene application, data visualization platform, data management, graphic editing, visual interaction and visual display.
- Computing resource pool and storage resource pool Build a smart traffic management analysis center, including traffic management applications, traffic incident detection, intelligent video structuring, and traffic resource information database. The video cloud storage system adopts a distributed cluster design and a virtualization design.
- Network Resource Pools describes the composition of network resource pools such as other private networks, centers, provincial public security, private video networks, core switches, border protection, border firewalls, and public security information networks.
- The integrated departments and users involved include science and technology, vehicle management, accidents, order, command, political work, equipment, publicity, windows, etc., and provide services such as auxiliary decision-making, command and operation, and integrated intelligence and supervision center.
- The traffic security center solution includes core data security, network security, terminal security, vulnerability scanning, anti-virus, border protection, key management KMS, etc., and builds a defense-in-depth system.
- Perception construction Construct an IoT sensing network in all scenarios of urban transportation, including full scenes, complete information, and complete equipment, involving pedestrians, motor vehicles, non-motor vehicles, and the environment.
- The front-end perception unit introduces the solutions of electronic police capture, large truck red light capture, intersection detention capture, pedestrian red light capture, as well as UAV high-point coverage, AR three-dimensional prevention and control, electronic license plate control and other solutions.
- The intelligent O&M management system includes unified O&M management, household registration management, and intelligent O&M management platform to realize functions such as operation monitoring, fault diagnosis, fault work order, and statistical analysis.
epilogue
Through the comprehensive use of intelligent technology, the smart transportation project aims to solve the problems existing in urban traffic management, improve traffic efficiency and safety, reduce environmental pollution, and improve the public travel experience. Through the construction of advanced intelligent transportation systems, the modernization of traffic management will be realized, and the sustainable development of urban transportation will be promoted.
