Abstract

The invention relates to a signalized intersection lane queuing length estimation method based on single-section electronic police data. The method comprises the following steps that: (1) the vehicledeparture time headway information of each lane is acquired through electronic police data, wherein the electronic police data is the time stamp information of vehicles passing a stop line, includingdeparture time, direction number, lane number and vehicle model parameters; and (2) according to the timestamp information and a vehicle departure time headway sequence, for a single-lane layout condition and a multi-lane layout condition, a feature function is defined to describe the double characteristics of the close distance and the time headway fluctuation, the change points of the departuretime headway sequence are identified, and the vehicle queuing length and the omission ratio on each lane in the period are estimated. Compared with the prior art, the method considers the error and missing detection phenomena of electronic police equipment, and has the advantages of complete scene coverage, 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...
