Abstract

The invention provides a multi-factor traffic risk real-time quantitative evaluation system and method, and relates to the technical field of intelligent driving traffic risk evaluation. The system comprises an information collection unit, a vehicle-mounted unit and road test equipment which are installed in a vehicle. The vehicle-mounted unit performs analysis processing according to driving data and traffic data obtained by the information collection unit and the road test equipment; the vehicle-mounted unit comprises a data acquisition module, a data processing module and a wireless data communication module; the road test equipment comprises an environment sensing module, a driving risk field establishing module, a model training module, a wireless data communication module, a data storage module and a data processing module. According to the system and method, existing historical traffic data and real-time traffic data can be considered at the same time, human, vehicle road factors are integrated, real-time quantitative evaluation of traffic risks is achieved, a theoretical basis and method support are provided for developing an intelligent driving decision technology, and the method and system have great application value.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving traffic risk assessment, in particular to a system and method for real-time quantitative assessment of multi-factor traffic risk. Background technique [0002] Road traffic risk is comprehensively affected by multiple factors in the three aspects of people-vehicle-road. Due to the complexity of road traffic and changing road conditions; the characteristics of drivers are different and their behavior is uncertain; the vehicle system is complex and performance coupling makes road traffic risk time-consuming characteristics of change, complexity, and coupling. The identification and assessment technology of road traffic risks can help drivers identify risks in advance, reduce the incidence of traffic accidents and casualties, and alleviate the severe situation of road traffic safety. In the field of digital signal processing, quantization refers to the process of approximating a ...
