Embodiment 1

[0040] This embodiment provides a method for evaluating the control effect of traffic signals at intersections using the Internet, which is applied to the traffic management department's evaluation system for the control effect of traffic signals at intersections, such as figure 1 shown, including the following steps:

[0041] S1: Obtain an electronic map capable of determining real-time road conditions on the Internet and adjust the scale of the electronic map to a preset ratio; therefore, the solution in this embodiment requires that the evaluation system must be able to connect to the Internet. like figure 2 As shown, in the display screen of the evaluation system, the scale of the electronic map is adjusted to a preset ratio, so as to ensure that the real-time road conditions at each entrance and exit of the intersection to be evaluated can be clearly seen.

[0042] S2: Select several coordinate points on each entrance direction and each exit direction of the intersectio...

Embodiment 2

[0051] The method for evaluating the control effect of the intersection signal machine provided by the Internet is applied in the evaluation system of the traffic management department, such as image 3 shown, including the following steps:

[0052] S1: Obtain an electronic map capable of providing real-time traffic conditions on the Internet and adjust the scale of the electronic map to a preset ratio.

[0053] S2: Select a number of coordinate points on each entrance direction and each exit direction of the intersection to be evaluated on the electronic map

[0054] S3: Read the real-time traffic conditions of each coordinate point;

[0055] S4: According to the real-time road conditions of each coordinate point, it is judged whether the road conditions of the coordinate points at each exit of the intersection to be evaluated are all smooth; if so, enter step S5, otherwise return to step S3;

[0056] S5: Determine whether the road conditions of the coordinate points at eac...

Embodiment 3

[0063] This embodiment provides a device for evaluating the control effect of intersection signals by using the Internet, which is applied to the evaluation system of the traffic management department, such as Figure 4 shown, including:

[0064] The map adjustment unit 1 obtains an electronic map capable of determining real-time road conditions on the Internet and adjusts the scale of the electronic map to a preset ratio; therefore, the solution in this embodiment requires that the evaluation system must be able to connect to the Internet. like figure 2 As shown, in the display screen of the evaluation system, the scale of the electronic map is adjusted to a preset ratio, so as to ensure that the real-time road conditions at each entrance and exit of the intersection to be evaluated can be clearly seen.

[0065] Marking unit 2, selecting several coordinate points on each entrance direction and each exit direction of the intersection to be evaluated on the electronic map; as...

Abstract

The invention discloses a method and a device for achieving evaluation of a control effect of an intersection signal machine by using internet. The method comprises the following steps of: obtaining a real-time traffic status of an electronic map directly through the internet; adjusting the measuring scale of the electronic map to a fixed proportion; selecting coordinate points at each entrance and each exit of an intersection to be evaluated; reading the real-time traffic status corresponding to the coordinate points on the electronic map directly; obtaining traffic status information of each entrance and each exit of the intersection to be evaluated according to the real-time traffic status; and judging an evaluation effect of a signal light by directly using the traffic status information. By use of the method, an accurate evaluation result can be obtained without setting data acquisition equipment including a motor vehicle detector and the like at each intersection, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of road traffic signal control, in particular to a method and device for evaluating the control effect of an intersection signal machine by using the Internet. Background technique [0002] It has become a necessary means of traffic management to allocate the right of way of vehicles and pedestrians through signal lights at level road intersections to ensure the safety and smoothness of intersections. How to evaluate the control effect of signal lights in real time has attracted people's attention. [0003] At present, there are two ways to evaluate the control effect of signal lights. One is to collect data manually on site, and then analyze the control effect of the intersection off-line. This method generally uses sampling methods, which not only have poor data accuracy, but also cannot be continuous. Response signal control effect; another device that can monitor the signal control effect of intersection in real t...
