Embodiment Construction

[0013] Docking station electronic fence such as figure 1 shown, where the line segment The edge on which is the entry edge, the line segment The edge where it is located is the outgoing edge, and the vector Same lane driving direction, line segment Along the side of the stop. The rectangle ABCD corresponds to the electronic fence at the stop. The coordinate accuracy of the four vertices of the electronic fence is at the centimeter level, and the accuracy of the real-time positioning point of the bus is at the lane level. According to the relationship between the bus and the electronic fence at the stop, the inbound and outbound behavior of the bus is judged.

[0014] Among them, Gaussian transformation is used to transform the longitude and latitude coordinates of the electronic fence and bus location points into plane rectangular coordinates.

[0015] This embodiment further explains in detail the setting of the electronic fence at the bus stop and the judging method ...

Abstract

The invention provides a method for judging the entry and exit of a bus based on the electronic fence of the bus stop, comprising: collecting the centimeter-level coordinates of the first and last points on the side where the bus stop is located and setting the width of the road; Transform the longitude and latitude coordinates of the electronic fence and the bus location point to the rectangular coordinates of the plane, and calculate the coordinates of the four vertices of the rectangular electronic fence, which are perpendicular to the direction of the road and divided into the entry side and the exit side according to the entry intersection and exit intersection ; Determine whether the current position of the bus and the position of the last second are contained in the electronic fence rectangle, and then determine whether the bus enters, exits or stops at the bus station.

Description

technical field [0001] The invention relates to a public traffic control technology, in particular to a method for judging the entry and exit of a bus based on the electronic fence of a bus stop. Background technique [0002] The operating efficiency of buses is related to the overall operating efficiency of public transportation in the entire city. It is the best way to quickly divert people, facilitate citizens to travel, reduce road pressure, and relieve urban traffic congestion. The currently commonly used bus signal priority trigger judgment method is to use radio frequency identification (RFID) or geomagnetic facilities to judge whether the bus has entered the bus signal priority trigger area. Changes in traffic lights give priority to buses. This method greatly increases the investment due to the need for additional installation of special equipment, including equipment on board the bus and equipment on the road. [0003] Currently, the bus is equipped with a GNSS t...
