The Effectiveness of Deer Advisory Messages on VDOT's Changeable Message Signs:Phase II

Following recommendations from an earlier Virginia Transportation Research Council (VTRC) study, in 2015 the Virginia Department of Transportation (VDOT) began to post animal advisory messages on the changeable message signs along I-64 in the Afton Mountain area in response to observations of frequent deer-vehicle collisions (DVCs) and high roadside deer activity in this area, particularly in the fall months. A followup limited scope study was recently conducted that suggested this approach might have had a positive impact on vehicle speeds and DVCs. The purpose of the study is to conduct more extensive analysis of speed and crash data on this segment of I-64 to more conclusively determine the effects that the deer advisory messages have on reducing DVCs.
