Method and system for drawing timing diagram of traffic intersection signal

Abstract

A method and system for drawing a traffic intersection signal timing diagram, wherein the method includes: establishing intersection geographic coordinate configuration information in the same format as that of a road network information database on a client; obtaining the intersection geographic coordinate configuration of the client corresponding to the traffic intersection to be drawn information, and analyze the geographic coordinate configuration information of the intersection to obtain the geographic coordinates of the intersection; read the road network information of the traffic intersection corresponding to the geographic coordinate position of the intersection from the road network information database according to the geographic coordinates of the intersection, wherein, The road network information includes crossing information, isolation strip information, zebra crossing information, and green belt information; according to the road network information and using a drawing engine to draw a schematic base map of traffic crossings; obtain the time series data of the signal lights at traffic crossings that need to be drawn, according to The timing data draws the status of traffic lights on the schematic base map of traffic intersections to obtain the timing diagram of traffic intersection signals. Through this scheme, the real-time performance of obtaining the signal timing diagram of the traffic intersection is improved.

Description

technical field

[0001] The invention relates to the traffic field, in particular to a method and system for drawing a traffic intersection signal sequence diagram. Background technique

[0002] With the development of society and economy, the public's demand for and attention to traffic information is also increasing.

[0003] At present, traffic monitoring is often realized by drawing the timing diagram of traffic intersection signals. In the traditional method, the user must draw a picture of the traffic intersection with the help of drawing software according to the actual situation of the intersection in advance as a schematic base map of the traffic intersection, and the traffic signal machine draws the traffic status of the traffic intersection on the schematic diagram according to the time series data of the sensor. Since it is necessary to draw the schematic base map of the traffic intersection according to the actual situation every time, the workload is heavy, the...
