Evaluating safety risk of locating above ground utility structures in the highway right-of-way
El Esawey, Mohamed; Sayed, Tarek;
Abstract
Roadside safety has been a concern for highway engineers and designers for many decades. A significant part of this concern is related to collisions with utility poles. Current practices and standards for placing utility poles are based on a combination of qualitative guidelines/heuristics and relatively outdated findings. Accordingly, there is a need to study the safety level associated with placing utility poles at different lateral offsets from the edge of the travel-way. In this paper a Safety Performance Function (SPF) is developed to relate roadway and roadside variables to utility pole collision frequency. It was found that increasing the poles offset has a more significant effect on reducing the frequency of utility pole collisions compared to increasing poles spacing. Based on the developed utility pole-SPF, design charts were provided to facilitate calculations and decision-making process. The developed utility pole-SPF was compared to a widely-used utility pole collisions model and the differences in the type of data and the development methodology were highlighted. © 2012 Elsevier Ltd.
