A method for real-time acquisition of road condition information oriented to mobile speed

Abstract

The invention discloses a real-time road condition information acquisition method orienting to cellphone traveling speed, and belongs to the field of intelligent transportation. The method includes: historical traffic data mining, road traffic condition speculation and road traveling speed calculation. The method orients to the cellphone traveling speed calculated through cellphone signaling data, and road condition data are obtained by integrally calculating the traveling speed. Due to the fact that the cellphone traveling speed is obtained on the basis of network wireless positioning technology, existing mobile communication facilities and network resources are fully utilized, and acquisition of round-the clock real-time road traffic information covering whole road network can be achieved through a little investment. The road condition information infusion calculation method orienting to the cellphone traveling speed can meet the demands of real-time road condition calculation in vast areas.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a real-time acquisition method of road condition information oriented to the moving speed of a mobile phone. Background technique [0002] In recent years, information technology has been continuously applied to the field of transportation, traffic information resources have been continuously enriched, and the means of traffic information services have been gradually improved. By providing traffic information to the public, travelers can make good plans before traveling and avoid congested sections during travel, so as to effectively utilize roads and reduce congestion. [0003] Efficient real-time traffic information collection is the foundation of an advanced traffic information service system. There are two types of traffic information collection methods: fixed collection and mobile collection. The traditional fixed collection method is difficult to achieve traffic ...

Problems solved by technology

For example, mobile phone carriers come from a wide range of sources, including people on foot along the road, passengers on buses and cars, and drivers of non-motorized vehicles. It is a sample that can be used for road condition calculation. Because the carrier is difficult to distinguish, the calculated road condition information cannot reflect the road traffic situation faithfully; The sample size of mobile phone users who receive and make calls (triggering communication events) in different time periods fluctuates greatly, which causes deviation (jitter) in the calculation of road travel speed; these situations make the calculation of road condition information inaccurate
