Real-time planning and dynamic scheduling system for urban emergency rescue channel

Abstract

The invention discloses a real-time planning and dynamic scheduling system for an urban emergency rescue channel, which is designed based on real-time traffic road condition information. The system can accurately and reasonably plan a rescue path according to initial spot and real-time road condition information. The system which is different from a common GPS (global position system) navigation not only finds out a channel, but also plans a path consuming shortest passing time according to real-time road condition information, and further, limits such as single line, left turn restriction and the like are not required to be considered, so that the planning technology is a brand new multi-objective path planning algorithm which integrates conventional path planning algorithms. Besides, the emergency channel is established dynamically and removed after used, so that daily traffic is prevented from being influenced excessively. After an emergency occurs, the system can dynamically schedule an emergency rescue unit according to an event type and grade, simultaneously, a dynamic emergency channel planning module of the system timely schedules one emergency channel based on the real-time road condition information, and guarantees that the emergency rescue unit arrives at the event scene in shortest time; an upper computer of a monitoring room performs data communication with a caution light board in a short message manner, and a purpose of dynamically establishing the special emergency channel is achieved; and the system adopts single serial port SMSMODEM to perform communication.

Description

Technical field [0001] The invention relates to a road planning system, in particular to a real-time planning and dynamic dispatching system for establishing an emergency rescue channel for urban emergencies. Background technique [0002] With the continuous development of society and economy, the speed of urbanization has accelerated, and the density of urban roads has also increased. The rapid development of the economy has brought great convenience to people’s lives. The continuous expansion of urban roads has made the space index of feasible routes in traffic a Doubled. At the same time, various uncertain sources of hazards and disaster-causing factors in the city have also increased significantly, leading to various emergencies in the city from time to time, causing heavy casualties and economic losses. After an emergency occurs, in order to minimize the adverse effects of the accident, the vehicles dispatched by the rescue center must be required to rush to the acciden...
