Vehicle-into-large-truck accidents produce a disproportionately large number of fatalities. It is hypothesized that increasing a truck's visibility or conspicuity will reduce the number of vehicles colliding with trucks. The purpose of this project was to thoroughly analyze this specific accident problem, design an augmented, low-cost reflectorized system for retrofitting on large trucks. Approximately 2,000 trailers were fitted with the augmented system and accident rates monitored and compared to those of a matched control group of 2,000 non-reflectorized trailers. Results indicated a statistically significant reduction in other vehicle collisions into reflectorized truck/trailer units of 16.3 and 21.2 percent respectively, during daylight and night time operations.
