Embodiment

[0048] Such as figure 1 and figure 2 As shown, a highway curve safety monitoring method includes the following steps:

[0049] S1 acquires the image of the road section the current vehicle is driving, and judges whether the road section ahead is a curve through feature recognition;

[0050] S2 If the road section ahead is a curve, obtain the current vehicle location through GPS positioning, and then match it with the GIS map to obtain the curve information. The curve information includes the radius of the curve, the slope of the longitudinal section, the length of the curve and the speed limit information etc.

[0051] S3 acquires the traffic flow status of the road section where the vehicle is located;

[0052] The traffic flow state includes five state levels of severe congestion, moderate congestion, light congestion, unobstructed and free flow.

[0053] S4 collects the personal information of the vehicle driver before entering the curve and the speed information of th...

Abstract

The invention discloses an expressway bend safety monitoring and early warning method, a system and a medium. The method includes the following steps that: the image of a road segment where a currentvehicle runs is obtained, whether a road segment ahead is a bend is judged through feature recognition; if the road segment ahead is a bend, bend information is obtained, and the traffic flow state ofthe road segment where the vehicle is located is obtained; the personal information of a driver before the driver enters the bend and the vehicle speed information of the current vehicle are acquired, and judgment is carried out, so that the level of the perception risk of the driver at the current moment is obtained; and the driving safety level of the current bend is obtained according to the physiological and psychological information of the driver, the bend information and the traffic flow state through an SVM neural network-based expressway safety level monitoring model, and corresponding operations are performed according to different levels. With the expressway bend safety monitoring and early warning method, the system and the medium of the invention adopted, the safety of the driving of the vehicle can be fully guaranteed.

Description

technical field [0001] The invention relates to the field of road safety monitoring, in particular to an expressway curve safety monitoring and early warning method, system and medium. Background technique [0002] The rapid development of expressways has driven the development of regional economic linkages, improved people's living standards, and promoted social development. However, while expressways bring convenience to people, there are also environmental factors such as complex terrain, many sharp bends and steep slopes, bad weather, and changeable road alignments on some expressways, as well as drivers who are not familiar with road sections and drivers perceive driving dangers. Factors such as a long time make the traffic safety problem extremely prominent. And the accident that takes place in the curve place is in very large proportion, so before entering the curve, it is necessary to carry out danger warning to the driver in advance. [0003] At present, the commo...
