SECTION V--DESCRIPTION OF STRATEGIES Related Strategies for Creating a Truly Comprehensive Approach The strategies listed in Exhibit V-1 and described in detail in the remainder of this section are either considered unique to addressing speeding and inappropriate speeds roadways, or are discussed in terms of their attributes specific to this. To create a truly comprehensive approach to the highway safety problems associated with speeding and inappropriately high speeds, agencies should consider including a variety of strategies as candidates in any program planning process. Appropriate strategies may be of five types: Public Information and Education Programs (PI&E)--Many highway safety programs can be effectively enhanced with a properly designed PI&E campaign, which includes coordination with media outlets. The primary experience with PI&E campaigns in high- way safety is to reach an audience across an entire jurisdiction (or a significant part of it). However, it may be desired to focus a PI&E campaign on a location-specific problem, such as an individual corridor with a history of severe crashes that have involved speed- ing. While this is a relatively untried approach compared with area-wide campaigns, use of roadside signs and other experimental methods may be tried on a pilot basis. Within this guide, PI&E campaigns, where application is deemed appropriate, are usu- ally used in support of some other strategy. In such a case, the description for that strat- egy will suggest this possibility (in the exhibits, see the attribute area for each strategy entitled "Associated Needs"). In some cases, where PI&E campaigns are deemed unique for the emphasis area, the strategy is explained in detail. Enforcement of Traffic Laws--Well-designed and well-operated law enforcement pro- grams can have a significant effect on highway safety. It is well established, for instance, that an effective way to reduce the occurrence of crashes and their severity is to have jurisdiction-wide programs that enforce an effective law against driving under the influ- ence of alcohol (DUI), or driving without seatbelts. When that law is vigorously enforced with well-trained officers, the frequency and severity of highway crashes can be signifi- cantly reduced. This should be an important element in any comprehensive highway safety program. Enforcement programs, by the nature of how they must be performed, are conducted at specific locations. The effect (e.g., lower speeds, greater use of seatbelts, and reduced impaired driving) may occur at or near the specific location where the enforcement is applied. This effect can often be enhanced by coordinating the effort with an appropriate PI&E program. However, in many cases (e.g., speeding and seatbelt usage) the impact is area-wide or jurisdiction-wide. The effect can be either positive (i.e., the desired reduc- tions occur over a greater part of the system), or negative (i.e., the problem moves to another location as road users move to new routes where enforcement is not applied). Where it is not clear how the enforcement effort may impact behavior, or where it is desired to try an innovative and untried method, a pilot program is recommended. Within this guide, where the application of enforcement programs is deemed appropri- ate, it is often in support of some other strategy. Many of those strategies may be tar- geted at either a whole system or a specific location. In such cases, the description for V-5
