Embodiment Construction

[0079] refer to figure 1 , the principle of the present invention is as follows: First, the concept of an ideal path for a single vehicle is explained. The ideal path of a single vehicle refers to the ideal path of the vehicle obtained according to the traffic flow state of the transportation system without considering the constraints of the actual traffic network, so that the vehicle can meet the travel requirements, avoid congested road sections and reduce the running time.

[0080] The commonality between the ideal path of a single vehicle and the missile guidance problem is:

[0081] (1) The ideal path planning of a single vehicle is not limited by the actual traffic road, which is conducive to satisfying multiple goals (system optimization goals and user demand goals) at the same time. In the space environment, missile guidance is less restricted, which is more conducive to achieving multiple target requirements at the same time.

[0082] (2) The purpose of missile guid...

Abstract

The invention discloses a vehicle routing method for simulating missile guidance. The principle and the method are used for simulating missile guidance so that a missile needs to overcome earth gravity, air resistance and the like, and a vehicle can avoid congested road sections (save travel time) in running so that vehicle routing is realized. The method includes a global mode and a stepping mode, and the two modes respectively have advantages. The stepping mode places particular emphasis on achieving a single-vehicle routing goal, and the global mode simultaneously achieves the single-vehicle routing goal and a system optimization goal. By being improved, the vehicle routing method for simulating missile guidance can also be used for realizing routing to avoid the congested road sections (save travel time) and shorten travel distance. The method is a dynamic routing method, and the single-vehicle routing goal can be changed when the vehicle runs. Compared with other methods, the method is suitable for routing of urban intelligent transportation, so that the vehicle using the method avoids the congested road sections.

Description

Technical field [0001] The invention belongs to the technical field of computer application and relates to vehicle path planning, in particular to a vehicle path planning method using computer software to simulate missile guidance, which is used for path planning of urban intelligent traffic. Background technique [0002] With the increasingly serious urban traffic congestion, the driver's call for route planning to avoid congested road sections (saving travel time) is getting louder and louder. Solving the path planning problem of vehicles avoiding congested roads (saving travel time) during driving can not only meet the goal of single-vehicle path planning, but also facilitate the optimization of the traffic system. That is, to make bicycles avoid congested road sections, and at the same time reduce the traffic flow of each congested road section of the system. [0003] The travel needs of most drivers are divided into: shortest travel time, shortest travel distance, or s...
