Method and device for positioning running direction of bus on bus lane

Abstract

The invention provides a method for positioning the running direction of a bus on a bus lane. The method comprises the following steps of obtaining GPS information of the bus lane, dividing the GPS information into n straight-line segments, extracting two end points of each straight-line segment and storing the end points together with parameter information of the corresponding bus lane to form a database; obtaining real-time positioning information of the bus; extracting lane information in the database one by one and comparing the lane information with real-time longitude and latitude information, and judging whether the bus is located on the bus lane or not; extracting running direction information of the bus lane if the bus is located on the bus lane; repeating the step if the bus is not located on the bus lane; judging the running direction of the bus within the bus lane; determining that the running direction of the bus is consistent to the direction of the bus lane and outputting a judgment result if a difference value of the real-time positioning information and the running direction information is within a set threshold value range; determining that the running direction of the bus is not consistent to the direction of the bus lane if the difference value is out of the set threshold value range. The invention further relates to a device for positioning the running direction of the bus on the bus lane.

Description

technical field [0001] The invention relates to the technical field of urban traffic management, in particular to a method and a device for locating the driving direction of a bus on a bus lane. Background technique [0002] At present, all large and medium-sized cities in my country are facing the pressure of urban traffic congestion. The average speed of buses assigned to drive in dedicated lanes is only between 10-15 km / h. Social vehicles illegally occupy bus lanes for a long time, resulting in " The phenomenon of "not dedicated bus lanes" is the main obstacle limiting the speed and capacity of buses. It is imperative to monitor bus-only lanes and punish illegal occupancy to improve the utilization of bus resources. [0003] Based on this, a new monitoring system has appeared in the existing technology, such as the MTCP-2000B system developed by Jiangsu Suke Changlian Technology Co., Ltd., which can effectively monitor bus lanes and effectively collect evidence for illega...

Problems solved by technology

[0004] However, in the process of monitoring and obtaining evidence, whether the driver drives the car on the bus lane, whether the direction of the bus is consistent with the direction of the bus lane, and whether there is a yellow line on the ground of the bus lane directly affect the efficiency of evidence collection.

At present, we can only rely on law enforcement personnel to review the evidence collection information again, and the misinformation of invalid evidence collection information also causes a waste of communication fees
