Abstract

The present invention discloses a system and method for evaluating urban road traffic zone servings levels based on actual measurements, belonging to urban road traffic management and control technique field. The technical project is that the system includes a microcomputer type microscopic traffic stream parametric synthesis measuring device, a remote management system, a background analysis software system, a zone traffic status modeling system, a traffic data information platform, and a zone traffic dynamic evaluation system. The method includes mounting the microcomputer type microscopic traffic stream parametric synthesis measuring device at site to collect the field data of coil, microwave and the like, transmitting the data to a data center through a network or communication, then implementing a series of analysis processes to the data to obtain intermediate and macroscopic models and parameters of the zone traffic status, and finally implementing the dynamic evaluation and emulation verification of the zone traffic status to provide safeguards for the harmonization operation of the urban traffic management.

Description

technical field [0001] The invention belongs to the technical field of urban road traffic management and control, and in particular relates to a system and method for evaluating service levels of urban road traffic areas based on actual measurements. Background technique [0002] The normal operation of urban road traffic is a vital issue related to people's lives. Due to the factors that make up the traffic system-the human-vehicle road environment is often disturbed by various natural or human factors, which destroys the coordination and safety of the traffic system, resulting in traffic accidents or traffic jams. These incidents may cause serious consequences, causing damage to the coordination and stability of the transportation system, severe traffic congestion in local or large areas, and seriously affecting people's travel. Monitoring and evaluating microscopic or regional traffic conditions has always been an important research content of traffic management departme...
