Problems solved by technology

[0004] However, most of the existing emergency plans for traffic emergencies are selected through the subjective judgment of the staff. Not only does it take a long time to deal with it, and there is a certain error in the accuracy of the selected emergency plan, but also because different traffic emergencies have great impact on drivers, The influence of road traffic flow and the environment is different. It is difficult for operators to consider the distribution of traffic roads, the impact on traffic flow, and secondary traffic accidents when selecting emergency plans, which leads to certain inconsistencies in the selected emergency plans. rationality

Embodiment 1

[0055] Embodiment 1: a kind of emergency plan matching method for traffic emergencies, such as figure 1 shown, including the following steps:

[0056] S1: Obtain traffic event information including event location information, event time information, event occupation information, and event status information;

[0057] S2: Obtain road distribution information within a preset distance range from the database according to the event location information, and obtain traffic flow information from the database according to the road distribution information and event time information;

[0058] S3: Calculate the processing time information based on the event occupation information, event status information and traffic flow information, and obtain the impact radiation range of traffic events based on the road distribution information and event occupation information, and calculate according to the processing time information and impact radiation range Obtain the membership value of the ...

Embodiment 2

[0086] Embodiment 2: a kind of emergency plan matching system for traffic emergencies, such as figure 2 As shown, it includes an information acquisition module, a data retrieval module, a first calculation module, a second calculation module, a third calculation module, and a matching module.

[0087] Wherein, the information obtaining module is used to obtain traffic event information including event location information, event time information, event occupation information, and event state information.

Abstract

The invention discloses an emergency plan matching method and system for traffic emergencies, a terminal and a medium, and relates to the technical field of intelligent traffic, and the key points of the technical scheme are as follows: obtaining traffic flow information from a database according to road distribution information and event time information; acquiring processing duration information by calculation, acquiring the influence radiation range of the traffic event by screening, and acquiring influence radiation membership values by calculation; calculating to obtain a traffic jam membership value; calculating to obtain an accident probability membership value; acquiring a membership weight coefficient by matching in the database, and acquiring a comprehensive membership value by calculation in combination with the influence radiation membership value, the traffic jam membership value and the accident probability membership value. The travel time influence of traffic emergencies on traffic flow in a radiation range, the traffic road congestion condition and the secondary traffic accident occurrence probability are comprehensively considered, a reasonable emergency plan is matched through the comprehensive membership degree, and the influence on all aspects after the traffic emergencies occur is balanced.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more specifically, it relates to a matching method, system, terminal and medium of emergency plans for traffic emergencies. Background technique [0002] Traffic emergencies refer to non-periodic traffic situations that lead to a decrease in road capacity or an abnormal increase in traffic demand. Traffic emergencies hinder or limit the normal operation of traffic flow, and have a significant negative impact on road capacity. [0003] At present, the road traffic management department classifies the traffic emergencies that may occur according to the type and degree. Usually, traffic emergencies are unpredictable, such as accidents, main road blockages, emergency situations in important places, vehicle breakdowns, bad weather, collapse of bridges or roads, scattered goods, traffic jams, etc. In order to deal with various emergencies, The traffic management departm...
