Drawing method and system for traffic intersection signal timing-sequence diagram

Abstract

The invention discloses a drawing method and system for a traffic intersection signal timing-sequence diagram. The method comprises the steps as follows: intersection geographic coordinate configuration information in the same format as a road network information data base is established on a client side; the intersection geographic coordinate configuration information of the client side corresponding to a traffic intersection to be drawn is obtained, and the intersection geographic coordinate configuration information is analyzed to obtain intersection geographic coordinates; according to the intersection geographic coordinates, road network information of the traffic intersection corresponding to an intersection geographic coordinate position is read from the road network information data base, wherein the road network information comprises intersection information, isolation strip information, zebra crossing information and green belt information; according to the road network information, a traffic intersection schematic base diagram is drawn through a drawing engine; and timing-sequence data of signal lamps of the traffic intersection to be drawn are obtained, traffic signal lamp states are drawn on the traffic intersection schematic base diagram according to the timing-sequence data, and the traffic intersection signal timing-sequence diagram is obtained. According to the method and the system, the instantaneity of obtaining of the traffic intersection signal timing-sequence diagram 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 a time series diagram of traffic intersection information. 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 a schematic base map of traffic intersections according to the actual situation every time, the workload is large, t...
