Problems solved by technology

However, if the existing technology is used, it is necessary to manually modify the parameters of the same element repeatedly.
For example, in the original plan, the left-turn flow rate of a certain intersection is 50 vehicles / hour, but in the current plan, the flow rate changes to 200 vehicles / hour, so the existing method is to first find the left-turn flow rate setting window of this intersection, Then change 50 to 200. When the number of intersections is large, it will take a certain amount of time to find the intersection, and it will take time to find the left-turn setting window of the intersection. When the amount of modified data is large, the same process must be repeated. operation, therefore, the workload will be very heavy

Embodiment Construction

[0017] The dynamic simulation method based on traffic microscopic simulation software includes pre-establishing the simulation road network model, opening the simulation file, generating the regional OD matrix, modifying the flow, timing and control measures, running, suspending and ending the simulation file, and outputting the evaluation results, etc. The steps are:

[0018] 1. Draw the simulated road network through traffic micro-simulation software, and define the ID attribute or NAME attribute of the elements of traffic flow, signal timing, and control measures according to certain coding rules, so as to facilitate the search and matching of elements, and save the simulation project file so that it can be used at any time transfer.

[0019] 2. Use the secondary development language of the simulation software to open the simulation project file under a certain path, and build an editing environment for road network elements.

[0020] 3. Use the development language to set...

Abstract

The invention relates to a microscopic traffic simulation running method, particularly to input of the traffic at a crossing. According to the method, a functional module framework is established; and computer program instructions control a computer system to fulfill a task and are stored in a readable storage medium of the computer. The invention aims to simplify a user's input work for the traffic at the crossing in microscopic traffic simulation software and improve the operation efficiency. Therefore, the microscopic traffic simulation running method is provided. The method is characterized by comprising the steps as follows: step A, the traffic data at the crossing are derived from a traffic information external device to a local prescribed route; step B, the traffic data at the crossing are imported from the local prescribed route; and step C, simulation is performed on the basis of the imported traffic data at the crossing.

Description

technical field [0001] The invention relates to a traffic micro-simulation operation method, in particular to the input of crossing flow. The method is completed by establishing a functional module framework and controlling a computer system by computer program instructions, and these computer program instructions are stored in a computer-readable storage medium. 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 p...
