Embodiment Construction

[0040] The virtual electronic fence is set on the electronic map, and is generally a polygon. Such as figure 1 As shown, there are 4 types of electronic fences, namely, the road section electronic fence 1, the intersection electronic fence 2, the stop electronic fence 3, and the field station electronic fence 4. The polygonal area enclosed by the virtual electronic fence is the electronic trigger area, and the corresponding bus entry strategy is preset. According to the different driving behavior of the bus in the electronic trigger zone, it is judged whether it is necessary to send the bus signal priority.

[0041] The coordinate system used in the present invention is as follows: the intersection o of the central meridian and the equator is used as the origin of the coordinates, the projection of the central meridian is the x-axis (north-south direction), and the projection of the equator is the y-axis (east-west direction) to form an xy coordinate system , The positive x-axi...

Abstract

The invention discloses a bus signal triggering priority determination method based on virtual electronic fence. The method includes the following steps: 1. arranging a virtual electronic fence on an electronic map and acquiring coordinate information of the virtual electronic fence, on the basis of the driving direction of the roads that are fenced by the virtual electronic fence, arranging an entrance strategy, wherein the virtual electronic fence includes a terminal yard terminal electronic fence, bus stop electronic fences, road section electronic fences and intersection electronic fences. The virtual electronic map forms a multilateral electronic triggering region; 2. determining the relationship between the current position of a bus and the electronic triggering region; 3. If the current position point of the bus is within the electronic triggering region, determining the current driving behavior of the bus; and 4. on the basis of the current driving behavior of the bus, determining whether to trigger a bus priority signal. The method uses the information acquired by using the electronic map and an onboard positioning navigation terminal, and real-time determines whether to trigger a bus priority signal.

Description

Technical field [0001] The invention belongs to the field of public transportation control, and in particular relates to a method for determining priority triggering of public transportation signals based on a virtual electronic fence. Background technique [0002] Public transportation priority can improve the overall operation efficiency of urban public transportation, and is the best way to quickly divert people, facilitate citizens' travel, reduce road pressure, and relieve urban traffic congestion. The current commonly used method for determining the priority triggering of bus signals is to use radio frequency identification (RFID) or geomagnetism to determine whether the bus has entered the bus signal priority trigger area. If it enters the area, the bus signal will be sent first to control the corresponding The change of traffic lights gives priority to buses. This method requires additional installation of special equipment, including bus equipment and road equipment, wh...
