Traffic flow information monitoring equipment setting method and system

Abstract

The application relates to the intelligent traffic technical field, and especially relates to a traffic flow information monitoring equipment setting method and system; the method comprises the following steps: a, determining primary areas-of-interest, and calculating contiguous relations between the primary areas-of-interest; b, gradually merging the primary areas-of-interest according to the contiguous relations, thus obtaining novel interested units; c, calculating the monitoring equipment number needed by vehicle information monitoring between the novel interested units, and setting the monitoring equipment according to the calculation result. The traffic flow information monitoring equipment setting method and system can reduce the areas-of-interest finess degree so as to reduce the monitoring equipment demands, thus providing the maximum vehicle information coverage ability between the areas-of-interest, and preventing the conditions in which the needed equipment number exceeds the present budget.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a method and system for setting up a vehicle flow information monitoring device. Background technique [0002] Along with the rapid growth of my country's urbanization level, the rapid development of urban traffic motorization has brought huge challenges and pressures to the service capabilities of urban traffic systems. The rapid increase in the number of motor vehicles has caused the urban ground transportation system to face increasingly serious traffic congestion problems, and the monitoring of traffic flow information is the main way to evaluate the road traffic status. In recent years, traffic flow OD (Origin and Destination, starting point and destination) information plays an increasingly important role in traffic demand analysis. Through the analysis of the temporal and spatial dynamic changes of the traffic flow OD information, it can scien...

AI Technical Summary

Problems solved by technology

Taking the camera as an example, in the case of a limited number, it is impossible to cover all the road sections that can pass between any two areas of interest, and the OD information of the vehicle will therefore be neglected.

Secondly, in the site selection of equipment facing the road section, the possibility of vehicles appearing repeatedly in different road sections on the main road with large traffic volume is higher. There is a large degree of duplication

Finally, in the current equipment site selection, it is generally given the road network and specific goals to calculate at least how much monitoring equipment is needed and where to deploy it. There are few research cases where the selection of facility locations is made under the condition of limited equipment.
