3、tation Engineering Affiliation: School of Transportation Science defines the test conditions, and tests drivers night vision recognition distances to cross-street pedestrians under different lighting conditions and driving speeds. These data or information is important to later analysis. Secondly, t
4、his paper compares the differences of visual recognition environments from four aspects of lighting conditions, traffic volume, vehicle speed and pedestrian crossing and analysis the differences of drivers visual recognition distances with different speeds and clothing colors between day and night.
5、Based on the data, analysis of the variation of drivers visual recognition distances along with the change of driving speed in different lighting conditions is conducted and night visual recognition distance-speed model in different lighting conditions is established. According to the speed survey,
6、this paper divides night driving speeds into low, medium and high grade and analysis the variation of drivers visual recognition distances along with the change of illumination intensity at different driving speeds, and then establish night visual recognition distance-illumination intensity model at
7、 different driving speeds. Finally, establish night visual recognition distance-speed-illumination intensity model. Based on the relation between safety-stop distance and visual recognition distance, found the safety driving conditions. According to the critical safe driving conditions, deduce the l
8、imit speeds-illumination model and illumination-design speeds model to do some case analysis. At last, give some advices on street light layout of pedestrian crossing. Key words: night limit speed, visual recognition distance, pedestrian crossing, cross-street pedestrians, illumination intensity 哈尔滨
