Evaluations of Low Cost Safety Improvements Pooled Fund Study

The tables below summarize the balloting results of the March 8th Low Cost Safety Improvements Pooled Funds Study meeting as delivered to the committee members. The purpose of the March 8th meeting was to develop a prioritized list of low–cost safety improvement strategies. Representatives from each the 23 State DOTS participating in the study and the FHWA, voted on 61 safety improvement strategies. The 61 strategies were broken down into three categories: Lane Departure Strategies (17), Unsignalized Intersections Strategies (37), and Aggressive Driver Strategies. Each state and the FHWA had one ballot in which they ranked their top ten strategies of interest from one to ten, with one being the highest. The top ranked strategies were then assigned points such that each representative’s top strategy received ten points, their second strategy received nine points, and so on. The points were then totaled and the strategies were ranked.

Table 1 displays the top 21 strategies based on the balloting at the meeting. Of the 21 strategies, 10 are Lane Departure Strategies, 9 are Unsignalized Intersection Strategies, and 1 is an Aggressive Driver Strategy. The strategy with the highest overall score was Install edgeline “profile marking,” edgeline rumble strips or modified shoulder rumble strips on section with narrow or no paved shoulders. It received a total score of 138, the highest number of ballots, and it received the most top priority votes with five states selected it as their top priority.

Table 2 displays the top two strategies in each of the three categories. In addition, where the strategy falls in the overall ranking of strategies is also shown. The ballots column shown in the table refers to the number of individual representatives that voted for that strategy. Therefore by dividing the total score by the number of ballots cast, the average score per ballot was calculated.
