Abstract

The invention discloses an expressway portrait evaluation and safety risk research and judgment system based on multi-source data, and the system comprises a data collection subsystem, a risk research and judgment processor and a research and judgment output subsystem, wherein the data collection subsystem comprises a traffic flow acquisition unit, a road index acquisition unit, an emergency response time acquisition unit and an accident illegal data acquisition unit; the risk research and judgment processor is connected with the data collection subsystem and is used for analyzing the data acquired by the data collection subsystem to obtain a risk analysis result; and the research and judgment output subsystem is connected with the risk research and judgment processor and is used for displaying the risk analysis result of the risk research and judgment processor. Through application of the system, data in multiple aspects are collected for risk research and judgment, the expressway safety risk research and judgment level can be improved to a great extent, expressway risk hidden dangers can be researched, judged and recognized in an all-round mode, and the expressway traffic safety level is accurately improved.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a multi-source data-based expressway image evaluation and safety risk research and judgment system. Background technique [0002] As an important traffic road in the expressway, it is necessary to carry out comprehensive and multi-angle safety risk assessment on the expressway. Due to the constraints of data limitations and other conditions, the current safety evaluation methods and systems applied to roads are relatively single and lack scientific and reasonable Therefore, it is urgent to propose a multi-source data highway portrait evaluation and safety risk research and judgment system, which has important practical significance and application urgency. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of single data and single evaluation method in the existing road safety evaluation, so a...
