Embodiment Construction

[0071] The present invention will be further described below in conjunction with specific embodiments.

[0072] like figure 1 As shown, the urban road traffic accident emergency rescue path planning method provided by the present invention includes the following steps:

[0073] 1) Generate the urban road network topology diagram, obtain the urban road network structure information, the urban road network real-time traffic flow data, the urban road network short-term traffic flow prediction data, and the rescue starting and ending location information, etc.

[0074] The urban road network structure information includes urban road network intersection adjacency information and road section length information, and the urban road network structure information can be obtained from the urban planning and design scheme; the urban road network real-time traffic flow data includes the urban road network. The real-time information of the average driving speed and the average delay of c...

Abstract

The invention discloses an urban road traffic accident emergency rescue path planning method which comprises the following steps: 1) generating an urban road network topological structure chart, and obtaining traffic flow data and rescue starting and ending point information; 2) analyzing urban road traffic accident emergency rescue characteristics, and selecting a proper rescue path planning method evaluation index; 3) constructing a basic framework of the timing coevolution path planning, and explaining an optimization principle of the timing coevolution path planning systematacially; 4) designing a suitable solving algorithm based on the operational characteristics of urban road vehicles; 5) defining a calculation method of uncertainty factors in the actual traffic environment of the urban road network; 6) outputting the rescue route planning result through computer programming. The invention can solve the problem of urban road emergency rescue path planning.

Description

technical field [0001] The invention relates to the technical field of optimality and stability of emergency rescue path planning for urban road traffic accidents, in particular to a planning method for emergency rescue paths for urban road traffic accidents. Background technique [0002] Emergency rescue is a key means to prevent the further deterioration of the impact of urban road traffic accidents and ensure the safety of the injured. According to the World Health Organization, the number of people injured in road traffic accidents is 30 million to 50 million every year, of which about 1.2 million are injured and die, that is, an average of 3,300 people die every day, and the number of casualties will increase by about 65% in the next 20 years. The frequent occurrence of traffic accidents and the sharp increase in the number of injured people force the emergency response efficiency to be further improved in order to control the injuries of the injured, restrain the secon...
