Abstract:

This paper concentrates on the optimal allocation of resources of road safety measures. All over the world, attempts are constantly being made to increase road safety by reducing the number of injuries and fatalities in road crashes. For this purpose, national safety plans are developed. These plans usually include a set of different measures, each one contributes separately to the increase of road safety, and their overall cost should not exceed a predefined budget constraint. Similar to most budget allocation problems, it is generally assumed that each safety measure delivers a certain benefit, and the set of selected measures should be based upon these individual benefits. However, such a view ignores the fact that in many cases the measures themselves are interdependent. Hence, their mutual implementation may change the overall benefit they deliver, and may affect their inclusion in the optimal set of selected measures. This problem, which has received extensive coverage with respect to transportation projects selection in general, has not received the same attention with respect to safety measures. However, the special character of safety measures calls for such an attention. This work attempts to fill this gap by presenting a methodology for optimal selection of safety measures that considers interdependence relations. This methodology is then demonstrated using a set of 60 potential safety measures, in which both the safety benefits and travel time benefits are considered.
