| 摘要： | In Texas, commercial vehicle safety is increasing in priority due to the rising volume of truck traffic and the disproportionate percentage of crashes and fatalities involving large trucks. One particular safety issue is the visibility of signing and pavement markings at night from a commercial driver's perspective. Through a nighttime controlled field study, the relationship between vehicle type (passenger car versus commercial vehicle) and sign/pavement marking material was evaluated in terms of the legibility distance of signs and the end detection distance of pavement markings. Additional research issues included investigations among sign type (guide, destination, and speed limit) and age (young, middle-aged and old). The findings indicate that the commercial vehicle provided statistically longer legibility distances than the passenger car. However, an examination of headlamp illuminance suggests that the headlamp illuminance of the commercial vehicle used in the nighttime controlled field study was higher than the average headlamp illuminance of on-road commercial vehicles. |
