A method for acquiring road condition data of a traffic guidance screen

Abstract

A method for acquiring road condition data on a traffic guidance screen, which is not bound to a single data source, can efficiently switch the traffic condition data source of the guidance screen, and has a low technical solution cost and is easy to implement. S1: According to the location of the traffic guidance screen, set the starting point and ending point of the section where the traffic situation is released, and all subsequent data acquisition is based on the starting point and ending point; S2: Obtain the latitude and longitude coordinates of the starting point and ending point; S3: Call the path planning of the third-party data company Interface to obtain the point sequence of the path from the start point to the end point; S4: connect two adjacent points in the point sequence with a line segment, and describe the path between the start point and the end point; S5: confirm the drawn point between the start point and the end point The correctness of the direction of the path; if the direction is correct, save the latitude and longitude coordinates and point sequences of the starting point and the ending point; if the direction is wrong, repeat steps S2 to S5 until the direction is correct; S6: Call the traffic interface of the third-party data company to obtain the starting point Traffic data for the route between and the destination.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a method for acquiring road condition data of a traffic guidance screen. Background technique [0002] With the acceleration of urbanization, urban traffic problems are becoming more and more serious and deteriorating, among which smoothness and safety are the two most prominent problems. Most cities in China use intelligent transportation systems for traffic control management. The intelligent transportation system consists of many subsystems, and the traffic guidance system is an important part of it. Many cities have built a large number of urban traffic guidance screens. Traffic guidance screens are often used to publish real-time urban traffic conditions, safe driving promotional slogans, weather information, and illegal information. [0003] The existing data acquisition method of the traffic guidance screen usually binds the data interface to the datab...
