Abstract

The invention discloses a signal intersection road travel time calculating method based on mobile phone switching data. The method comprises the steps of: 1, collecting mobile phone switching data of complete travelling of a vehicle and signal timing information of a passed intersection; 2, calculating a free travelling time and a congestion time of an upstream road of the intersection, and obtaining the time when the vehicle arrives at the intersection; 3, according to the time when the vehicle arrives at the intersection and the signal timing information of the intersection, determining the waiting time of the vehicle; and 4, calculating the complete travelling time of the vehicle. Combined with the signal timing scheme and the mobile phone switching data, the method can be used for precisely calculating the travelling time of the vehicle on the road where the coverage range of the mobile phone is switched, real-time and accurate road condition information is provided, and convenience is provided for a driver.

Description

technical field [0001] The invention belongs to the field of urban road condition information collection in traffic surveys, and in particular relates to a method for calculating travel time at traffic signal intersections based on mobile phone switching data. Background technique [0002] The acquisition of urban road conditions information, especially the accurate travel time of road sections, can provide drivers with faster route selection, reduce the flow of traffic on congested sections of the road network, and balance the traffic flow of the entire road network. For large cities, alleviating traffic congestion on the road network can make a great contribution to the city's economic development and air quality improvement. Currently, there are three main ways to obtain the travel time of a link: [0003] (1) Utilize taxi GPS data (Global Positioning System, a global positioning system, a geographic positioning device that can obtain vehicle current latitude and longitu...
