Abstract

The present invention relates to a method for estimating the queuing length of lanes at signalized intersections based on single-section electric police data. The time stamp information of the vehicle passing the stop line, including the departure time, direction number, lane number and vehicle model parameters; 2) According to the time stamp information and the time sequence of the vehicle leaving the headway, for single-lane layout conditions and multi-lane layout conditions, pass The characteristic function is defined to describe the dual characteristics of approaching distance and headway fluctuation, identify the change point of the departing headway sequence, and estimate the vehicle queuing length and missed detection rate in each lane within the period. Compared with the prior art, the present invention takes into account the phenomenon of false and missed detection in electric police equipment, and has the advantages of covering all scenarios, less input data, wide applicability, and the like.

Description

technical field [0001] The invention relates to the field of traffic information, in particular to a method for estimating queue length of lanes at signalized intersections based on single-section electric police data. Background technique [0002] As an important node in the urban road network, signalized intersections are also frequent locations of traffic congestion. Queue length can vividly and intuitively reflect the degree of intersection congestion, and it is one of the important indicators for evaluating the operational efficiency of intersections, and is also an important parameter for the optimization of intersection signal control. On the other hand, more and more cities in our country have deployed electric police detectors, and massive electric police data can provide rich traffic information. Compared with traditional fixed-point detectors, the electric police data has a high degree of recognition, can accurately record vehicle departure information, and can r...
