C-1 A P P E N D I X C Countermeasure Cost-Effectiveness Summary After individual poles or a series of poles along a corridor are identified as high-risk (either based on utility pole crashes or based on their placement in high-risk locations) , the next questions relate to what treatments may be justified.

From page 112... ... C-6 Utility Pole Safety and Hazard Evaluation Approaches REDUCE POLE DENSITY Reducing utility pole density can include three different types of strategies: (1) increasing the spacing between poles, (2) Read the entire page →
From page 113... ... Countermeasure Cost-Effectiveness Summary C-7 Multiple pole use, or doubling up the types of utility lines carried by the same poles, has been a common practice by utility companies for many years. This includes having electric, telephone, cable, television, and other communication services, in addition to supporting luminaires along highway rights-of-way, in an effort to decrease distribution costs.

C-8 Utility Pole Safety and Hazard Evaluation Approaches TABLE C4: SUMMARY OF BENEFIT/COST RATIOS FOR MULTIPLE POLE USE TABLE C5: SUMMARY OF THE MINIMUM NUMBER OF UTILITY POLE CRASHES TO ENSURE COST-EFFECTIVENESS OF MULTIPLE POLE USE IN URBAN AREAS COMBINE REDUCTION IN POLE DENSITY AND POLE RELOCATION FURTHER FROM THE ROAD This treatment is less common since it not only requires space to move the pole further from the road but also means that the utility owner must decide to use more structurally strong poles in order to handle the added weights per pole of having increased spacing. Costs for this measure Read the entire page →

From page 117... ... Countermeasure Cost-Effectiveness Summary C-11 recommended prior to the final selection of a countermeasure, and the Utility Pole User Guide allows for such a more refined cost-effective analysis to select the optimal solution for a given roadway and utility pole situation. SELECTION OF COST-EFFECTIVE COUNTERMEASURES Based on the calculation of B/C ratios for the utility pole treatments discussed above, the Zegeer and Parker study developed a series of tables that provide an overview of which countermeasures are generally cost-effective (i.e., have a B/C cost ratio of 1.0 or above) Read the entire page →
From page 118... ...

From page 119... ... Countermeasure Cost-Effectiveness Summary C-13 poles/towers since none of these treatments was cost-effective due to the extremely high cost of moving these poles and/or the high cost of undergrounding the power lines. TABLE C8: GUIDELINES FOR COST-EFFECTIVE COUNTERMEASURES FOR UTILITY POLE CRASHES: TELEPHONE LINES AND POLES IN RURAL AREAS It should be noted that the information in Tables C9 through Table C12 provides general guidelines on which of the countermeasures are cost-effective for a given combination of site conditions, using average countermeasure costs obtained from dozens of utility companies across the nation.
