APPENDIX B Example of Recommended Crash Reduction Program and Roadside Safety Treatments C Paul Scott CRASH REDUCTION PROGRAM A concentration of crashes at a site or in a small area, or a certain type of crash that seems to occur over and over in a given jurisdiction, may indicate that the highway/utility system is contributing to crash potential.

agency to discuss their proposed crash reduction programs and the types of data they will need to identify sites for further study. Once law enforcement officers are aware of the need to collect data on the number and types of utility devices involved in collisions, the availability of such data usually improves.

Analyzing High-Crash Locations A site may be selected for further study because of the number, rate, or severity of utility pole collisions, or because it fits a pattern of sites that have been designated for systemwide improvements. After a site has been identified for further analysis, the analyst begins looking for patterns of crash types and causes.

Reviewing the Crash Reduction Program An important part of a crash reduction program is to determine whether previous treatments have worked. This involves periodic review of the sites after the treatments have been installed to make sure they have functioned as intended.

Even with underground utility lines, there still may be a need to safety treat ground surface pad-mounted transformers, switch cabinets, pedestals, and other associated hardware. When these devices are installed, they should conform to the applicable clear zone guidelines.

clearance requirements. Some rules require that poles be placed at lateral property lines.

Poles on the outside of a horizontal curve, where a lane becomes narrow, at the end of a lane drop, and in other locations where vehicles are likely to travel close to them are candidates for such warning where more comprehensive treatments are not justified. Selecting Countermeasures The method used for selecting countermeasures depends on the size and complexity of the project.

which is full of tables, graphs, and charts that can predict the number of traffic crashes involving utility poles of different configurations. Once an agency has decided to undertake a treatment program, it can use this methodology to test alternative designs to see which yields the most cost-effective treatment.
