| Accidents during nighttime construction are major concerns in urban areas. More data for nighttime work zone safety studies are needed to support the decision making process of construction operations. The main objective of this paper is to evaluate what type of accidents most frequently occur.;This study focuses exclusively on nighttime construction zone accidents which occurred in Riverside and San Bernardino counties from 2006 to 2009. The data is analyzed using ANOVA and Regression analysis.;The findings of the study indicate a driver is likely to be involved in a sideswipe, rear end, hit other object or overturn accident. The leading cause for the accident is speeding, making an illegal turn, or improper driving with the movement of the driver prior to the accident being traveling straight, stopped or marking a right turn.;Nighttime construction accidents can be reduced with a better understanding and knowledge of how they occur. |
