Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of road rescue management and relates to an intelligent road rescue management platform based on big data analysis. Background Art
[0002] With the rapid development of the economy and the improvement of the transportation system, people's travel methods have gradually become more diverse. As a necessary means of transportation for urban travel, the serious harm caused by bus accidents is self-evident. Therefore, road rescue management for its sudden problems is particularly important.
[0003] Current roadside assistance management mainly involves a person calling a roadside assistance hotline when a bus breaks down or is involved in an accident. The roadside assistance management center then dispatches a corresponding vehicle to rescue the bus. However, the current technology still has the following problems:
[0004] First, due to the large passenger capacity of buses, the loss rate caused by their failure is also high. Currently, only rescuing buses after a failure occurs cannot effectively reduce the harm caused by bus accidents. At the same time, the buses have already caused certain damage, which cannot reduce the loss rate of bus failures and cannot ensure the safety of passengers.
[0005] Secondly, bus accidents or breakdowns are often not isolated incidents and often involve certain situations. However, personnel are not sufficiently aware of these situations. The current practice of regular vehicle inspections by personnel has certain limitations and cannot reduce the accident rate of buses, nor can it reduce the difficulty of road rescue, nor can it improve the efficiency of road rescue.
[0006] Third, the current method of conducting road rescue by having people call the rescue hotline has the problem of untimely calls, which cannot improve the timeliness of bus rescue, nor can it reduce the safety hazards of personnel caused by bus failures or accidents, nor can it improve the rescue effect, and the degree of intelligence is low.
