SECTION V--DESCRIPTION OF STRATEGIES EXHIBIT V-1 (Continued) Objectives and Strategies to Address Motorcycle Collisions Objectives Strategies 11.1 G Increase safety enhancements 11.1 G1 Include motorcycles in the research, development, and for motorcyclists deployment of ITS (E) 11.1 H Improve motorcycle safety 11.1 H1 Develop and implement standardized data gathering and research, data and analysis reporting for motorcycle crashes (N/A) 11.1 H2 Include motorcycle attributes in vehicle exposure data collection programs (N/A) 11.1 H3 Develop a set of analysis tools for motorcycle crashes (N/A) Note: P = Proven, T = Tried, and E = Experimental. See further explanation below. Classification of Strategies The strategies in this guide were identified from a number of sources, including the literature, contact with state and local agencies throughout the United States, motorcycle organizations representatives, and federal agencies. Some of the strategies are widely used, while others are used at a state or even a local level. Some have been subjected to well- designed evaluations to prove their effectiveness, while others, including some that are widely used, have not been adequately evaluated. Due to the varying degree to which each strategy has been used, as well as the limited knowledge about the effectiveness of most of the strategies, the reader should be prepared to exercise engineering judgment before adopting a particular strategy for implementation. To help the reader, the strategies have been classified into three types, each identified by a letter: Proven (P): Those strategies which have been used in one or more locations, and for which properly designed evaluations have been conducted that show it to be effective. These strategies may be employed with a good degree of confidence, with the understanding that any application can lead to results that vary from those found in previous evaluations. The attributes of the strategies that are provided will help the user make judgments on which is the most appropriate for their particular situation(s). Tried (T): Those strategies that have been implemented in a number of locations, and may even be accepted as standards or standard approaches, but for which there have not been found valid evaluations. These strategies, while frequently or even generally used, should be applied with caution; users should carefully consider the attributes cited in the guide and relate them to the specific conditions for which they are being considered. Implementation can proceed with some degree of assurance that there is not likely to be a negative impact on safety, and very likely to be a positive one. It is intended that as the experiences of implementation of these strategies continue under the AASHTO Strategic Highway Safety Plan initiative, appropriate evaluations will be conducted, so that effectiveness information can be accumulated to provide better estimating power for the user, and the strategy can be upgraded to a "proven" one.
