Single vehicle origin-destination (OD) acquisition method based on passing vehicle electric alarm data

Abstract

The invention relates to a single vehicle origin-destination (OD) acquisition method based on passing vehicle electric alarm data. The method comprises steps of acquiring traffic original data like passing vehicle electric alarm data, performing data preprocessing, analyzing historical data, and calculating a vehicle passing time threshold of all adjacent electric alarm stops; then generating vehicle traveling records of a to-be-checked vehicle and corresponding vehicle passing time based on passing vehicle electric alarm data, and identifying vehicle OD and vehicle traveling track by using the vehicle passing time threshold; finally, checking and repairing vehicle traveling track according to the upstream and downstream relationship between stops, and showing on a map. The method fully utilizes vehicle passing electric alarm data, and introduces vehicle passing time threshold on the basis of analysis of historical data, thereby acquiring more accurate single vehicle OD; furthermore, checking and repairing of the vehicle traveling track help solve a problem of lacking of original data, so that the method is more suitable for actual traffic environment. The method has characteristics of simple operating process, low calculating cost, and strong applicability.

Description

technical field [0001] The invention relates to the acquisition of OD (Origin-Destination) of a single vehicle in the field of intelligent transportation, that is, the investigation of the traffic origin and destination of a single vehicle. The OD acquisition of a single vehicle can be used to analyze traffic demand and serve as the basis for traffic planning, traffic design, traffic evaluation and road construction. Background technique [0002] With the development of the urban economy and the expansion of the scale, the number of motor vehicles has increased rapidly simultaneously. Due to the increase in vehicle travel demand and the uneven distribution of travel demand, urban traffic problems such as traffic congestion and environmental pollution have arisen. The construction of intelligent transportation system with traffic signal control as the core can reduce traffic accidents, alleviate traffic congestion and reduce environmental pollution to a large extent.

AI Technical Summary

Problems solved by technology

[0005] To sum up, at present, the existing vehicle OD acquisition methods mainly have the following problems: 1) The traditional vehicle OD acquisition method uses a manual method, which consumes a lot of resources, high time cost, and the data quality is not high. 2) Other existing vehicle OD acquisition methods also have some problems: the floating vehicle technology has the disadvantages of limited sample data and low acquisition accuracy, and the mobile phone signaling technology has the difficulty of data acquisition, Problems such as high computing cost, while the existing bayonet electric police system has defects and deficiencies such as limited coverage and acquisition accuracy affected by various external factors
