Urban commuting path identification method and device

Abstract

The present invention relates to the field of intelligent transportation, and provides a method for identifying urban commuting routes, including: obtaining OD points of vehicles; dividing a commuting travel generation area and a travel attraction area according to the OD point data, where n is a natural number; matching the OD points to form OD point pairs; according to the passing points and frequency information of the vehicle, construct and generate the commuting route of the vehicle. The invention performs full sampling on the road traffic information, and more accurately reflects the phenomenon and essence of urban commuting. On the one hand, it can reflect the distribution and evolution characteristics of urban morning and evening peak commuting traffic flow, and provide a scientific basis for an accurate understanding of urban traffic; Improve the level of traffic control and improve the satisfaction and comfort of residents' travel.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and equipment for identifying urban commuting routes. Background technique [0002] Commuting traffic occupies the vast majority of urban traffic, which has the characteristics of extremely large traffic flow in a short period of time, fixed travel routes, and mainly resident population. Frequent congestion, air pollution, traffic accidents and other problems caused by commuting traffic have become chronic problems in the city and need to be solved urgently. [0003] Commuting traffic reflects information such as the starting point, ending point, and driving path of most vehicles in the city. This information can provide a reference for parking lot planning, traffic area division, and path-level signal control. [0004] However, urban traffic managers still lack effective means and ways to understand commuter traffic. Generally, questionnaire surveys, GPS posit...

AI Technical Summary

Problems solved by technology

[0004] However, urban traffic managers still lack effective means and ways to understand commuter traffic. Generally, questionnaire surveys, GPS positioning data calculations, etc. are used to obtain commuter traffic starting point, end point, route and other information.

However, due to the small sample size of the questionnaire survey and the limited number of vehicles equipped with GPS positioning equipment, the commuter traffic information obtained by the above two methods is only part of the large-scale commuter traffic in the city and cannot fully and accurately reflect the large-scale commuter traffic in the city. transportation
