Abstract

In the allocation of funds and the scheduling of projects, alternative improvements for all possible locations must be evaluated in a multiyear framework in order to optimize the effectiveness of the entire highway safety improvement program within the constraint of a given budget. A procedure is developed that can be used for optimal allocation of funding available for highway safety improvement projects on a statewide basis. In the model, the reduction in the total number of accidents is the measure of effectiveness. The constraints include total funding available each year. The model formulation can consider carry-over of unspent funds. A stochastic version of the model is also discussed. A variety of other conditions required by or associated with the policies and objectives of the transportation agency can also be formulated as binding constraints. The application of the model is illustrated. Through a series of sensitivity analyses the impact of the funding level on the effectiveness of a hypothetical highway safety program is evaluated.
