Abstract
The invention provides a reflector setting method for improving the traffic safety at a curve section of an expressway. In the method, reflectors with different edge ratios are arranged on the two sides of the curve entering the curve section of the expressway based on the visual perception edge ratio of a driver, thus the driver has different speed perceptions on the two sides of the curve, the speed perception on the outer side of the curve is greater than the speed perception on the inner side of the curve for sure, the driver drives a vehicle to the inner side subjectively in the driving process at the curve section, the centrifugal force in the turning process is offset, and the running track is kept at the center of the lane; and moreover, the speed perceptions of the driver on the two sides of the curve section of the expressway can be changed so as to actively control the running track of the vehicle, and the lane keeping effect of the curve section of the expressway is improved.
Description
Technical field
The invention belongs to the traffic safety technology field, be specifically related to a kind of novel trans light modulation method to set up that is used to control speedway bend highway section vehicle driving trace of setting about from driver's visual perception characteristic.
Background technology
Bend is the main highway section that road traffic accident takes place.From the quantity of accident, 2007, totally 128034 of the traffic accident of China on bend reached 42.18% of total accident number.From accident intensity, the dead intensity of the average annual bend of 1997-2006 China continues to be in 30 people/hundreds' time a high position, and injured intensity then time rises to 168 people/hundred time from 82 people/hundred, and bend road section traffic volume severity of injuries is constantly aggravated.Traffic safety level in bend place has the trend of the deterioration quickened.
From the form of accident, one of main reason of road traffic accident during the improper track of deviation, according to the statistical analysis of road traffic accident, it is relevant that worldwide nearly 44% motor-vehicle accident and vehicle depart from normal lanes.In the statistics of traffic accidents database of Volvo Aktiebolaget, have 33% accident to result from run-off-road approximately, during serious personal injury's accident of about 40% because run-off-road causes.2007; The side collision that China takes place because of the motor vehicle run-off-road; Totally 138034 of subtend and scraping accidents in the same way; Account for 42.18% of total number of accident, its death toll that causes reaches 24063 people, and direct economic loss reaches 3.41 hundred million (do not take into account collision pedestrian, the collision trackside safeguard procedures that cause because of automotive run-off-road as yet and go out the relevant accident that embankment causes).This explanation takes rational measure to make vehicle keep normal lanes, will well improve the traffic safety level.
When being analyzed, the reason of road traffic accident finds that the people is the main cause that causes road traffic accident.Show that according to related data about 90% traffic accident is caused by driver and pedestrian.According to relevant the reporting the result of the U.S., 90% traffic accident is that people's mistake causes; According to China the ASSOCIATE STATISTICS of traffic accident is found that 80% above traffic accident reason is relevant with the driver.And in human factor, the perception mistake accounts for 48.1%, and misjudgment accounts for 36.0%, and the reaction mistake accounts for 7.9%.According to the interrelated data introduction, obtain in the information the driver, more than 80% visual information.Therefore; Visual information from the driver; The research driver turns to the influence factor of behavior at the bend place; Analyze visual signature, the vehicle operating characteristic of driver, explore and propose the scientific and reasonable method that turning around a curve is induced that helps based on driver's visual information at bend, significant to the traffic safety level that improves the bend place.
