Embodiment Construction

[0035] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, a method for determining a driving safety level based on field theory disclosed in an embodiment of the present invention includes the following steps:

[0037] (1) Obtain all vehicle microscopic data within the research range, where the vehicle microscopic data includes vehicle speed, acceleration and position data.

[0038]Specifically, the research range in this embodiment may be designated manually, or the research range may be delineated with a certain set distance as a radius centered on the researched target vehicle. The acquisition method of vehicle micro data can be obtained from the collected video files or text files of road traffic conditions, and can also be obtained through the Internet of Things and cloud d...

Abstract

The invention discloses a method and device for determining a driving safety grade and based on a field theory. The method comprises the steps that microscopic data of all vehicles in a research areaare obtained, and the microscopic data comprise the vehicle speed, the acceleration speed and position data; action valves of other vehicles in the research area on a target vehicle are calculated, the action valves comprise the speed sub-item action value and the acceleration speed sub-item action value; the weighted average action value of all the vehicles on the target vehicle is calculated; and the driving safety grade of the target vehicle is determined according to the weighted average action valve. According to the method for determining the driving safety grade and based on the field theory, two-vehicle interaction of vehicles in a certain range is synthetically considered, safety evaluation of the target vehicle is more reliable, the evaluation result is more accurate, a scientific and reasonable judgment and decision basis are further provided for a driver and the vehicle, and guarantee is provided for road traffic safety.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method and device for determining a driving safety level based on field theory. Background technique [0002] According to the statistics of the United Nations, in today's "automotive era", 1.3 million people are killed by traffic accidents worldwide every year, and 20 to 50 million people are caused non-fatal injuries due to road traffic accidents. The vast majority of these victims are from developing countries. The World Health Organization predicts that by 2020, road traffic injuries will become the third largest factor in the global disease burden, surpassing AIDS or tuberculosis, and its title of "the world's first public hazard" is worthy of its name. In my country, with the general improvement of the economic level and the development of related technologies in the automobile industry, Chinese people continue to increase their automobile consumption. As of t...
