Embodiment 1
[0031] figure 1 It is a schematic flowchart of a traffic simulation control method in an embodiment of the present invention. Such as figure 1 Shown, a kind of traffic simulation control method, described method comprises:
[0032] Step 110: Obtain the traffic flow at the first intersection;
[0033] Specifically, obtain the traffic flow situation of the first intersection, check whether the traffic flow is in a saturated state, and obtain the specific quantitative value of the traffic flow at the first intersection.
[0034] Step 120: Obtain the traffic flow change of the second intersection related to the first intersection;
[0035] Specifically, obtain the traffic flow change of the second intersection related to the first intersection, the second intersection is an adjacent intersection that can divert vehicles for the first intersection, and the change of the traffic volume of the first intersection is Traffic flow plays a role at intersections.
[0036] Step 130: O...

Abstract
The invention provides a traffic simulation control method and a traffic simulation control device. The traffic simulation control method includes acquiring vehicle flow of first intersections; acquiring vehicle flow change of second intersections related to the first intersections; acquiring first influence degrees of the vehicle flow change of the second intersections on the vehicle flow of thefirst intersections according to the vehicle flow change of the second intersections; judging that congestion is about to occur at the first intersections when the first influence degrees are higher than first preset thresholds. The traffic simulation control method and the traffic simulation control device have the advantages that the technical problem of deficiency of advanced warning and timelyguidance during traffic paralysis due to vehicle flow over-saturation in the prior art can be solved by the aid of the traffic simulation control method and the traffic simulation control device; technical effects of clearly assisting in analyzing and predicting traffic congestion sections and reasons, timely adopting corresponding measures, carrying out advanced warning for congested sections and quickly carrying out traffic guidance to guarantee normal road driving can be realized.
Description
technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a traffic simulation control method and device. Background technique [0002] Traffic simulation uses computer science and technological achievements to establish a traffic model that can replace reality. This model can reproduce the characteristics of the actual traffic system and analyze the possible behavior of the traffic system under various setting conditions. Through the results of model simulation tests, we can seek Optimal solutions to realistic traffic problems, evaluation of the effects of various design schemes of transportation facilities, and direct technical support for the design, development and performance optimization of various transportation products, and help in persuading traffic management decision-makers to adopt new traffic concepts. It has the advantages of high efficiency, safety, less constraints by environmental conditions, and can change ...
