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 r...

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0031] The analysis of traffic flow OD information aims to analyze the transfer information of vehicles between areas of interest that can attract vehicles to park. Considering that the movement of the vehicle depends on the traffic road network, the road segment associated with the ROI (that is, the road segment starting from or entering the ROI) determines the number of monitoring devices, that is, the rougher the ROI, The smaller the number of associated road sections, the smaller the number of monitoring devices required to cover vehicle OD information between regions of interest. Bas...

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...
