25 This chapter summarizes some of the most relevant studies previously conducted on utility pole safety. In particular, it addresses research that attempted to quantify the effect of various traffic and roadway features on the frequency and severity of crashes into utility poles.

30 Utility Pole Safety and Hazard Evaluation Approaches To illustrate the results of applying the predictive model to a countermeasure such as pole relocation, consider the values of the crash-reduction factors shown in Table 4. The first column lists the utility pole distance in the current situation; the proposed new pole offset distances are shown at the top of each of the remaining columns.
