Area road network traffic safety situation early warning system and method thereof

Abstract

The invention discloses an area road network traffic safety situation early warning system and a method thereof. The system comprises monitoring equipment, a data transmission system, a data process system and an early warning system. The method comprises the following steps: acquiring data information of road traffic, meteorology, illegal behaviors, and accidents through the monitoring equipment; sending the data information through the data transmission system; carrying out a multiple heterogeneous treatment on the acquired data information through the data process system, and merging data of the same kind; analyzing and assessing early warning grade through the early warning system, and determining and publishing a early warning scheme. Thereby road network traffic safety situation information can be comprehensively grasped, and dangerous source existing in the road network can be discovered timely to determine an early warning grade and generate an intelligent early warning countermeasure. Pertinence, instantaneity and validity of a measure of a road traffic management department actively preventing traffic accidents are improved. Technology support is provided in the invention to reduce area road network traffic risk factor and prevent major and extraordinarily serious road traffic accidents.

Description

technical field [0001] The invention belongs to the field of intelligent traffic management, and relates to traffic accident prevention, an intelligent traffic system (ITS), an event management system, etc., in particular to a system and method for early warning of road network traffic safety situation. Background technique [0002] According to statistics, the number of deaths in road traffic accidents in my country accounts for more than 73% of all road traffic accident deaths, the number of road traffic accidents in which more than 3 people die at a time accounts for more than 85% of the total number, and the number of deaths in highway traffic accidents accounts for more than 85% of the total number of deaths. The proportion of the number of people has been increasing year by year in recent years, and the traffic safety situation of the arterial road network composed of high-grade roads is very severe. The reason is that due to the incomplete and inaccurate grasp of the t...

Problems solved by technology

However, the design schemes developed by these systems have not yet been tested in actual engineering, so the existing problems need to be further identified and solved, and the corresponding theoretical algorithms need further research.

At the same time, although many new or existing expressways are equipped with traffic monitoring and management systems and catastrophic weather warning systems, there are always problems in these systems that the development of information resources lags behind the construction of hardware environments, poor information transmission and insufficient information sharing. Issues such as inability to transmit and release safety information synchronously, it is still not possible to provide all-weather (various weather conditions), all-round (various control methods) road traffic safety real-time and dynamic early warning of expressway network operation safety on the whole
