Embodiment Construction

[0054] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0055] In the embodiment of the present invention, such as figure 1 As shown in the figure, the identification system for frequent accident points of expressway is based on the TRANSCAD platform, and includes a data module for expressway construction, a data module for traffic operation status, a data module for traffic accidents and an identification module for frequent accident points;

[0056] In the embodiment of the present invention, the operation status of the Shenyang-Dalian Expressway is taken as an example for illustration; the Shenyang-Dalian Expressway is a two-way eight-lane expressway with a design speed of 120km / h and flat terrain along the way. A total of 11 survey sections were selected along the entire line, and the section distribution See Table 1:

Abstract

The invention provides an expressway black spot identification system and method, and belongs to the technical field of road safety evaluation. Based on a TRANSCAD geographic information system, expressway conditions, traffic conditions and historical accident data are integrated to provide a grading method of safety service levels, and expressways with different lanes and different design speeds are divided into four safety levels via the relation between the traffic volume and the number of accidents, so that the technical method system of expressway safety evaluation is enriched; a black spot identification method integrating safety service level and quality control is proposed, so that the disadvantages of single evaluation are effectively avoided, and the fairness of relevant evaluation is improved; and the system and the method effectively improve the normalization of expressway traffic data and accident data management, improve the black spot identification efficiency and practicability, improve the expressway safety level, can import other expressway data according to road pile numbers at any time, and are based on the framework of the system.

Description

technical field [0001] The invention belongs to the technical field of road safety evaluation, and in particular relates to a system and method for identifying frequent occurrence points of expressway accidents. Background technique [0002] According to the statistics of the World Health Organization (WHO), since 2007, the annual traffic accident death toll in the world has reached 1.24 million, accounting for 2.5% of the total global annual death toll. Traffic safety has become a global issue; However, compared with foreign developed countries, there is still a big gap; statistics show that in 2013, there were about 200,000 traffic accidents in my country, resulting in about 60,000 deaths. Traffic accidents are still the biggest problem in my country's production safety field. One of the challenges. [0003] Driving safety on highways is an important part of road safety; by the end of 2014, the total mileage of highways in China had exceeded 110,000 kilometers, ranking firs...
