A Guide for Reducing Speeding-Related Crashes

SECTION IV - Index of Strategies by Implementation
Timeframe and Relative Cost

A central tenet of the AASHTO Strategic Highway Safety Plan and its application at the state or local level is the time and cost to implement. Emphasis is on identifying strategies that are low cost (and hence able to be implemented on a broad or systematic basis), and take little time to implement. Time to implement addresses the urgency of achieving meaningful reductions in fatalities as quickly as is possible. In developing this and other similar guides, strategies that appear effective yet are clearly expensive and/or time-consuming were excluded.

Exhibit IV-1 provides a classification of strategies according to the expected timeframe required for implementation and relative cost to implement and operate each strategy for this emphasis area. In several cases, the implementation time will be dependent on such factors as the agency's procedures, the number of stakeholders involved, and the presence of any controversial situations. The range of costs may also be somewhat variable for some of these strategies, due to many of the same factors.

Placement in the table below is meant to reflect costs relative to the other strategies listed for this emphasis area only, rather than relative to strategies discussed in other guides in the NCHRP Report 500 series. The estimated level of cost is for the commonly expected application of the strategy, especially one which does not involve additional right-of-way or major construction, unless it is an inherent part of the strategy.
