Distribution and characteristics of crashes at different locations within work zones in Virginia
2001 (English)Report (Other (popular science, discussion, etc.))
Abstract [sv]

Work zones tend to cause hazardous conditions for vehicle drivers and

construction workers since these work zones generate conflicts between

construction activities and the traffic, and therefore aggravate the existing

traffic conditions. This study investigated the characteristics of work zone

crashes in Virginia that occurred between 1996 and 1999. The information on

each crash was obtained from the police crash records. Each crash was located

in one of five areas of the work zone: 1) advance warning area; 2) transition

area; 3) longitudinal buffer area; 4) activity area; and 5) termination area.

An analysis of the percentage distributions was then carried out, with

respect to the locations of the crashes, the severity, collision types and

different types of highways. The proportionality test was used to determine

significant differences at the 5% significance level. The results indicate

that the Activity Area (Area 4) is the predominant location for work zone

crashes regardless of the highway type, and that rear-end crashes are the

predominant type of crashes. However, the results also indicated that the

proportion of the sideswipe in same direction (SS) crashes in the Transition

Area (area 2) is significantly higher than that in the Advance Warning Area

(Area 1).
