Abstract

The invention provides a city signal control intersection traffic state detecting and evaluating system based on data characteristic and a method and an application thereof. The system comprises a vehicle state detection unit, a control state monitoring unit, a signal collecting unit, a microprocessing unit, a data transmitting unit, a data processing unit and a traffic state display unit, wherein, the vehicle state detection unit and the control state monitoring unit are connected with the signal collecting unit in parallel; then the signal collecting unit is also connected with the microprocessing unit, the data transmitting unit, the data processing unit and the traffic state display unit sequentially; the microprocessing unit is also connected with a real time data storage unit signal; and the control state monitoring unit is also connected with a traffic signal lamp signal. The method is applicable to various traffic engineering technology activities carried out by traffic real time data analysis, and the method has the advantages of intuition, easy application, high judgement accuracy and wide application range.

Description

technical field [0001] The invention relates to the state evaluation technology of urban traffic system, in particular to a data feature-based urban signal control intersection traffic state detection and evaluation system and its realization method and application. Background technique [0002] Urban traffic congestion is an important issue that affects the economic development and the quality of life of residents in our country. Implementing traffic signal control strategies to reduce delays; publishing real-time traffic information to induce vehicles to drive is a traffic management measure to maintain the dynamic balance of the road network and alleviate traffic congestion. These two traffic management measures are based on the premise of traffic status, especially the effective evaluation of traffic congestion. The "Urban Road Traffic Management Evaluation Index System" jointly formulated by the Ministry of Public Security and the Ministry of Construction of my country...
