Abstract

The invention discloses a traffic flow detector layout method based on building block splicing, a server and a system. The method comprises a step of classifying intersections in a road network according to intersection types, a step of establishing traffic flow detector layout models based on different intersection types so as to form a model library, wherein a traffic flow detector is not constructed at only one road section in the road sections of the intersections for each traffic flow detector layout model in the model library, and a step of screening a traffic flow detector layout modelin the model library and laying the road network in the form of building block splicing.

Description

technical field

[0001] The invention belongs to the field of urban road traffic detectors, and in particular relates to a method for laying out traffic flow detectors based on building block splicing, a server and a system. Background technique

[0002] At present, the existing road detectors have problems such as low coverage, poor connectivity, and low accuracy, which not only cause waste of resources, but also cannot meet the requirements of urban road traffic data collection, traffic information release, and traffic management department management.

[0003] Through searching, it is found that the patent document CN 103489316A utilizes the law of flow conservation at intersections, establishes flow conservation equations, and prioritizes the detection of road sections according to road grades and costs. The number of detector layout and the rank of the detector optimization coefficient matrix are constrained conditions, and the detector layout optimization model is estab...
