Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing:

[0029] figure 1 It is a road network diagram with multiple disaster points and multiple shelters, including variable information boards set at nodes 3 and 5. The directed arc in the figure represents the road, and its direction indicates the direction of traffic flow on the road. If the road is not a one-way street, use two directed arcs with opposite directions. Each node represents an intersection, and the direction of the directed arc indicates the direction of traffic flow on the road. The weight in the directed arc has two parts, which respectively represent the maximum flow of the road and its average travel time.

[0030] figure 2 is processing figure 1 The road network diagram shown and the variable information board and the data structure diagram of the network flow model. Node represents a collection of intersections, and Pointer represents a pointer pointing...

Abstract

The invention belongs to the modern traffic control and the abductive technique field, disclosing a variable information board abduction area dynamic partitioning method, with the following steps: a. building the road net data structure through the forward direction incidence edge memory structure, meanwhile inducting the dynamic array Node showing the junction, the maxflux dynamic array showing the maximum flow of the road and the two dimension TurnFlux array showing the turning flow of the junction, building the extended forward direction incidence edge data structure; b. obtaining the traffic real-time information, the related information of each variable information board and the traffic ruler configuration information; c. modifying the road net data structure, building the dynamic net flow model; d. computing the abduction area of the time interval aiming to each variable information board through the built road net data structure and the net flow model. The invention has the advantages of causing the traffic of the whole area to trend towards the optimum.

Description

technical field [0001] The invention belongs to the technical field of modern traffic control and guidance, and mainly relates to a dynamic division of a variable information board guidance area used for travel guidance in traffic. Background technique [0002] With the development of traffic roads and a large number of means of transportation, the traffic situation has been paid more and more attention by the government and people. Especially in urban traffic, the road network is more complicated, the number of traffic vehicles is larger, and traffic congestion or traffic accidents cause a lot of economic losses and have a huge negative impact on people's daily life. [0003] In urban highway traffic network, variable message sign (Variable Message Sign, VMS) has been applied more and more. It can not only induce the vehicle, but also has relatively simple technology and relatively low cost. It has received widespread attention and has a good application prospect. In Chin...
