Problems solved by technology
On the one hand, the existing evaluation focuses on the comprehensive evaluation of the effectiveness of road traffic safety treatment. The evaluation period is relatively long, usually in years. Dynamic appraisal; the second aspect is qualitative evaluation and quantitative evaluation simultaneously, the non-objectivity of qualitative evaluation will affect the fairness of evaluation results
The third aspect is that the basic data involved are often manually input, and human factors will affect the accuracy of the evaluation process and results
[0004] The problems and deficiencies in the prior art are: 1. There is no theoretical system and technology for urban road traffic safety situation assessment and early warning
2. The evaluation is relatively static, and it cannot realize the dynamic judgment of the security situation, and the early warning is not real-time
3. Human factors seriously affect the evaluation indicators, process and results, and the fairness and accuracy of the evaluation are unconvincing

Embodiment Construction
[0021] The present invention will be further described below in conjunction with drawings and embodiments.
[0022] Such as figure 1 Shown: Urban road traffic safety situation identification and early warning system includes traffic safety situation identification system, traffic safety situation early warning system and traffic safety countermeasure system.
[0023] (1) Traffic safety situation appraisal system
[0024] The traffic safety situation assessment system analyzes the characteristics, frequency, and related factors of traffic accidents in the city, evaluates the traffic safety status, finds out the evaluation objects with low traffic safety levels and the focus of early warning work; the traffic safety The situation identification system is automatically associated with the city's established traffic safety basic information system, dynamically updates relevant identification index information, and obtains the traffic safety situation of urban roads in real time b...

The invention relates to an identification and judgment early-warning system for urban road traffic safety situation. The identification and judgment early-warning system comprises a traffic safety situation identification and judgment system, a traffic safety situation early-warning system and a traffic safety handling countermeasure system, the comprehensive traffic safely handles the relevant basic information, such as traffic accident information, traffic violation information, motor vehicle and driver information, road information and the like, the traffic safety situation is graded basedon the identification and judgment index and the early-warning index, and the identification and judgment and the forecasting and early warning are performed to the urban road traffic safety situation. The invention has the advantages that the complete set of theoretical system and the technology for identification and judgment early-warning for the urban road traffic safety situation are provided; the dynamic identification and judgment and the real-time early warning of the safety situation are realized; and all the qualitative indexes are automatically obtained from the relevant information system, and the influences of the human factors on the identification and judgment indexes, the process and the result are basically eliminated.
Description
technical field [0001] The invention relates to a system for identification, evaluation, prediction and early warning of urban road traffic safety situation, which is suitable for urban road traffic safety treatment and accident prevention. Background technique [0002] Some international road traffic safety research organizations such as ERSO (European Road Safety Observatory) have established some general road traffic safety evaluation indicators. The risks of inter-regional traffic safety handling are analyzed and evaluated. In China, the Ministry of Communications has formulated the "Guidelines for Safety Evaluation of Highway Projects" (JTG / T B05-2004), which proposes the content, methods and standards for safety evaluation of expressways and first-class highways in my country, but the operating speed is mainly used. as an evaluation indicator. my country has formulated the "Evaluation Index System for Safe and Smooth Counties", which includes a total of 44 evaluation ...
