Embodiment 1

[0111] image 3 Shown is a schematic diagram of the interaction flow of the emergency vehicle dispatching method of Embodiment 1, and the specific steps are as follows:

[0112] Step 31: The OBU on the emergency vehicle sends a registration request message to the CSU, carrying information such as the vehicle identification (ID), vehicle type, destination address, current vehicle location, and speed of the emergency vehicle. The vehicle type can be a police car, a fire truck or an ambulance, etc.

[0113] Step 32: The CSU returns a registration confirmation message to the OBU. The registration confirmation message carries the optimal driving route planned by the emergency vehicle based on the destination address, current vehicle location and current traffic conditions. When the CSU plans the optimal route The basis may be a combination of one or more principles such as reaching the destination address in the shortest time, passing the least number of traffic lights to reach th...

Embodiment 2

[0137] The difference between Embodiment 2 and Embodiment 1 is that the CSU does not participate in the opening of the green channel, and when the emergency vehicle arrives at the management area of ​​the TCU, the TCU opens the green channel for the emergency vehicle according to the driving path of the emergency vehicle and the location of the vehicle. For the specific process, refer to Figure 6 shown.

[0138] Step 61: The OBU on the emergency vehicle sends a registration request message to the CSU, carrying information such as the vehicle identification (ID), vehicle type, destination address, current vehicle location, planned driving route, and vehicle speed of the emergency vehicle. The vehicle type can be a police car, a fire truck or an ambulance, etc.

[0139] The planned driving route is the emergency vehicle planning the optimal driving route for the emergency vehicle based on the destination address, the current vehicle location and the current traffic conditions. ...

Abstract

The invention provides a method and device for scheduling an emergency vehicle to save the running time of an emergency vehicle and improve the execution efficiency of the emergency vehicle for emergency tasks. The method is that: a traffic control unit acquires a scheduling instruction, and the scheduling instruction is used for instructing the traffic control unit to perform lane planning for the emergency vehicle; a driving path of the emergency vehicle is obtained; a fast driving lane is determined according to the driving path; and before the fast driving lane is occupied by the emergencyvehicle, the traffic resources are dispatched. In this way, the emergency vehicle can quickly pass through the management area of the traffic control unit, saving the emergency vehicle driving time and allowing the emergency vehicle to reach the destination address quickly to execute the emergency task.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a method and device for dispatching emergency vehicles. Background technique [0002] Intelligent Transportation System (Intelligent Transportation System, ITS) aims to establish a large-scale, comprehensive and real-time, accurate and efficient comprehensive transportation management system through the integration and application of advanced information, communication, sensing, control and computer technologies. .
