The system has the advantages of being flexible in deployment, low in implementation cost, and good in economy, practicality and reliability, provides diverse signal control methods and intelligent solutions for urban traffic managers, meanwhile, provides comprehensive and specific decision information support, and is suitable for being used in large-medium-small-sized cities so as to meet the requirements of intelligent traffic management and control badly needed in the prior art.

Description

technical field [0001] The invention relates to urban intelligent traffic, in particular to an urban road traffic signal control optimization system. Background technique [0002] The optimization of urban road traffic signal control plays an important role in alleviating urban road traffic congestion and improving the efficiency of urban road traffic operation. At present, a series of traffic signal control systems with signal control parameter optimization functions have been developed at home and abroad, and have been put into use in many cities, and achieved good application results, such as the SCOOT system in the UK, the SCATS system in Australia, and the CRONOS in France. system, RHODES system, OPAC system in the United States, ACS Lite system, HiCon system in my country, etc. [0003] However, with the increasing traffic congestion of urban roads in our country, most of the existing traffic signal control systems can no longer fully meet the needs of large and medium...

Problems solved by technology

[0003] However, with the increasing traffic congestion of urban roads in China, most of the existing traffic signal control systems can no longer fully meet the needs of large and medium-sized cities in China for intelligent signal control optimization and information services, which are specifically reflected in the following aspects: 1) There are great difficulties in the upgrading and optimization of the signal control system itself, which largely depends on the cooperation and participation of system manufacturers. The cost of system transformation is high and the subsequent expansion capability is weak; The system composition of multiple brands lacks a platform for unified coordination and information interaction, which makes it difficult to realize the synergistic benefits of signal control, especially in the case of traffic congestion, it is difficult to achieve collaborative optimization of the overall road network timing parameters; 3) signal The information sharing ability of the control system is weak, which causes it to be dissociated from other traffic operation control systems. Not only is there a waste of redundant construction, but it is also difficult to realize the benefits of collaborative operation between urban intelligent transportation systems; 4) The function of the signal control system is relatively single , signal control strategy configuration means are limited, and there is a lack of diversified information services and decision support such as traffic performance evaluation at intersections, monitoring of signal machine operation status, comparison and evaluation of signal schemes; 5) system functions lack systematic and reasonable design, and the system is artificially High degree of intervention, poor user experience
