Embodiment 1

[0045] This embodiment provides a method for evaluating the control efficiency of signal machines at intersections using mobile phone mobile data, such as figure 1 shown, including the following steps:

[0046] S1: Set the detection range on the electronic map of the intersection containing the traffic efficiency that needs to evaluate the control efficiency of the signal machine, such as figure 2 As shown, the starting line of the detection range coincides with the intersection stop line, and the detection range covers the preset distance upstream of the stop line; the maximum preset distance can be selected from the stop line position of the upstream intersection, or directly selected as 300 meters and other fixed distances.

[0047]S2: Obtain in real time the mobile phone data of all mobile phones within the detection range, the mobile phone data includes the ID number, location and moving speed of the mobile phone, and associate the mobile phone data of each mobile phone...

Abstract

The invention provides a method and a system of using cell phone mobile data to evaluate intersection signal control efficiency. A detection range is set in an electronic map comprising an intersection requiring evaluation of traffic efficiency of signal control efficiency, and the starting line of the detection range is superposed with an intersection stopping line, and the preset distance of the upstream of the stopping line is covered by the detection range. Cell phone data of all of cell phones in the detection range is acquired in a real-time manner, and comprises the ID numbers, the positions, and the moving speeds of the cell phones, and then the cell phone data of every cell phone is associated with the electronic map. The number of the cell phones stagnated in the detection range during red light time of each direction and the stagnated time of each cell phone are calculated accurately according to the cell phone data, and therefore the total stagnated time of the cell phones waiting for the red light is calculated, and is used as a total waiting time. Whether the intersection signal lamp control efficiency is ideal is evaluated according to a ratio between the red light waiting times of two directions, and the signal lamp efficiency is evaluated in a quantitative way.

Description

technical field [0001] The invention relates to the field of road traffic management, in particular to a method and system for evaluating the control efficiency of signal machines at intersections by using mobile phone mobile data. Background technique [0002] Road traffic congestion has attracted great attention from governments at all levels, and how to alleviate road traffic congestion has become a research topic for experts and scholars. Traffic congestion is caused by the imbalance between traffic supply and traffic demand. How to improve supply efficiency and alleviate traffic congestion is the key to satisfying traffic demand and alleviating traffic congestion. Traffic demand is mainly the movement of people and objects. Vehicle capacity of roads and intersections. In recent years, traffic management departments at home and abroad have paid more and more attention to the problem of people's mobility. Many cities have adopted strategies such as bus lanes and intersec...
