摘要
Abstract
In order to investigate the problem of traffic safety on highways through towns and villages due to the incorrect settings of warning signs, a case study is implemented at a section of Liuxin Road going through the Town of Bulaotun, Miyun District, Beijing.Based on related theory about drivers' behavior and their psychological/physiological characteristics, appropriate lead distances of warning signs on highways going through towns and villages are studied.It is found out that such lead distances should be between 70 and 90 meters based on the speed limit of 60 km/h for such highways.The above lead distances are also verified by the drivers' psychological and physiological data measured from a simulated driving test.The refinement of the locations of warning signs is considered to be an effective way to guide the driving process by eliminating wrong operations due to misleading information, and thus improve traffic safety on the highways going through towns/villages.关键词
