Embodiment Construction

[0078] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0079] like figure 1 As shown, a traffic flow simulation method based on the average road speed includes the following steps:

[0080] (1-1) Read the map model that needs to be simulated, and convert the file of the map model into a configuration file that can be directly read and used by traffic microscopic simulation software;

[0081] Traffic micro-simulation technology is a technology that simulates the operation rules of a single vehicle on a time scale of minutes or minutes to evaluate the interaction between highways and urban road systems or pedestrian systems. It is of great significance to describe and evaluate the traffic flow condition of the road network. Traffic micro-simulation software is software that uses traffic micro-simulation technology. At present, the commonly used traffic micro-simulation software mainly includes Vis...

Abstract

The invention discloses a traffic flow simulation method based on road average speed, and the method comprises the following steps: reading a map model needing to be simulated, and converting a file of the map model into a configuration file which can be directly read and used by traffic microscopic simulation software; generating a driving path of the vehicle in the simulation software by utilizing the configuration file; calculating an expected vehicle speed of the road section; checking the to-be-updated speed queue according to a preset updating frequency, and if a to-be-updated speed value exists in the to-be-updated speed queue, smoothly updating the simulation vehicle speed in the traffic microscopic simulation software; the method has the advantages that the simulation vehicle speed of the simulation environment can be smoothly updated, the simulation effect is more real, and instantaneous speed change of the vehicle at a certain time point is avoided; and during cyclic departure, the road selection of the vehicle is more reasonable, and the simulated flow of the road section can be more conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a traffic flow simulation method based on road average speed. Background technique [0002] Lane: Also known as driving lane and roadway, it is used on the road for vehicles to pass by. In the real environment, lane dividing lines are used to distinguish different lanes. [0003] Road: The set of lanes between two adjacent intersections (including intersections, diverging points, merging points, etc.) is called a road. [0004] Intersection: An intersection formed by the intersection of two or more roads. At the intersection, motor vehicles, non-motor vehicles, and pedestrians driving on different roads will cause traffic conflicts, so traffic control is needed to ensure the safe and orderly operation of the traffic process. [0005] Signal machine: The signal machine is an important device for controlling traffic signals at intersections, and is an important part of...
