A system and method for calculating vehicle traffic efficiency at an intersection

Abstract

The invention discloses a calculation system for vehicle traffic efficiency at an intersection, which includes: a data acquisition unit and a data processing platform; the data acquisition unit includes a microwave detector, and the microwave detector collects vehicle passing information at an intersection in real time and sends it to the data processing platform , and send the relative position information to the data processing platform at the same time, the relative position information is the distance information between the vertices at both ends of the road and the microwave detector; the data processing platform receives the intersection passing information from the microwave detector and relative position information, and calculate the traffic efficiency of vehicles at the current intersection according to the passing information and relative position information. The invention can regularly and automatically calculate the traffic efficiency of motor vehicles at designated intersections, comprehensively and accurately reflect the actual running status of motor vehicles at intersections and the degree of occupancy of space-time resources at intersections, and provide information for urban road network planning and signal evaluation. in accordance with.

Description

technical field [0001] The invention discloses a calculation system and method for vehicle traffic efficiency at an intersection, and relates to the technical field of intelligent traffic management. Background technique [0002] With the rapid development of our country's economy, cities have become important areas of economic growth. The population continues to increase, and the scale of cities is expanding day by day, followed by a rapid increase in the number of motor vehicles. The increase in the number of motor vehicles makes urban roads increasingly congested, and traffic jams often occur, which leads to a decrease in the use efficiency of urban roads and greatly limits the traffic capacity. [0003] Road traffic efficiency is similar to traffic capacity, and it is also a very important performance and index to measure road guidance vehicles, and it is also an important index of road design. Traffic capacity refers to the maximum number of vehicles that can pass thr...

Problems solved by technology

This concept can comprehensively compare and analyze the traffic efficiency of motor vehicle lanes, non-motor vehicle lanes, and pedestrian lanes. However, the types of motor vehicles and non-motor vehicles are complex, and there are often large errors in the number of people, and intersections are not All roads can be effectively driven, and the driving area cannot be accurately measured, resulting in serious distortion of the comparative analysis results
