Assessing the Necessity and Urgency of Traffic Safety Devices Maintenance on Rural Highways Using a Two-Stage Decision Making Method

Highway maintenance departments usually need to find out which road segments require the utmost attention for maintenance. This paper proposes a method to assess the necessity and urgency of traffic device maintenance on rural highways. This method is a two-stage decision making method combining both utility evaluation and site ranking. First, a quantitative method was developed to evaluate the utility of existing traffic devices based on the road segment level. Secondly, a multi-attribute decision-making problem was put forward taking AADT, road age, and the importance of the road segments within the road network into account. The method of minimizing the weighted sum of squared deviations was used to solve this problem. Based on the results of the two-stage method, necessary engineering improvements could be applied to selected sites with limited funds and time. Finally, the two-stage method was used in practical engineering projects.
