A Time-Space Analysis System for Traffic Accidents

Abstract

The invention provides a traffic accident time-space analysis system, comprising a data layer: collecting basic geographic information data, data cleaning and fusion checking, and establishing a standardized accident data warehouse; an application layer: according to the standardized accident data warehouse, analyzing the accident-prone area, digging out the cause, establishing the cause countermeasure database, and putting forward the rectification suggestions; and a display layer: displaying the analysis results of the application layer, including traffic accident information, frequent occurrence area, cause report, frequent occurrence position renovation proposal report. This system is based on a Browser / Server distributed architecture of a network geographic information system to build, improve traffic accident data management and analysis level, gets rid of the terminal restraint, and can be isolated traffic accident data integration analysis. Through the iteration of the coding algorithm, the exact location of the traffic accident can be obtained. The accident cause analysis model is established by using comparison statistics, regression analysis and cluster analysis model todiagnose the cause of traffic accident at the characteristic level, and the accident cause countermeasure database is established.

Description

technical field [0001] The invention relates to the technical field of network analysis, in particular to a space-time analysis system for traffic accidents. Background technique [0002] With the continuous construction of urban road traffic network, people's demand for convenient transportation has driven the continuous increase of car ownership. Followed by the high number of traffic accidents, road traffic safety has increasingly become a key issue that concerns the safety of people's lives and property, affects and restricts the quality and efficiency of economic and social development, and has received attention and attention in the national security strategy. With the widespread application of new technologies such as computers, the Internet, and sensors, people's lives have begun to enter the "big data era", and traffic accident data is one of them. The rapid development of geographic information processing technology, information mining technology, spatial analysis...

AI Technical Summary

Problems solved by technology

However, there is no comprehensive study of the internal relationship between various elements, so as to diagnose the cause of the accident at the characteristic level, and it is impossible to build a causal countermeasure library, and the collection of traffic accident scene data depends on the server, which is extremely inconvenient
