Problems solved by technology

Method 3 is an evaluation method for general urban road traffic order, which does not consider the characteristics of the weakened lane concept inside level intersections, and does not recognize the negative impact of the distribution of running trajectories and vehicle speeds on the traffic operation order of level intersections due to the weakened concept of lanes
[0003] Therefore, the current calculation of traffic order evaluation parameters at signalized intersections mainly follows the calculation method of traffic order evaluation calculation methods for general urban roads. For the discrete running trajectories caused by the weakening of the lane concept inside level intersections, there is no targeted evaluation parameter calculation method. , and no invention patents for this type of evaluation method have been retrieved
The existing technology lacks a more scientific and reasonable parameter solution method for the evaluation of traffic order at level intersections

Abstract

The present invention proposes a method for solving traffic order evaluation parameters at level intersections based on track data. For level intersections, based on vehicle track data, the vehicle running track deviation and running speed deviation are solved, and the vehicle running track deviation and running speed deviation are calculated based on the vehicle running track deviation and running speed deviation The trajectory deviation and speed deviation of each lane, flow direction and intersection are obtained, so that the present invention can reflect the discrete characteristics of the running track of the level intersection, and can evaluate the traffic order of the level intersection.

Description

technical field [0001] The invention belongs to the technical field of traffic evaluation at level intersections, in particular to a method for solving traffic order evaluation parameters at level intersections based on track data. Background technique [0002] Intersections are key areas of urban road traffic. In recent years, with the increasing demand for refined traffic design and precise traffic control at intersections at home and abroad, the controllability requirements for traffic order at intersections have also been raised. As the basis of traffic efficiency and safety, traffic order is the guarantee of precise management and control. According to the literature search of the prior art, it is found that there are mainly the following types of evaluations on the operation of grade intersections: 1) Evaluation of the operation efficiency of grade intersections: mainly including traffic capacity, delay and queuing length. Its observation methods mainly include manua...
