by a comprehensive potential cost/benefit analysis (Recommendation 7-1). Particular emphasis should be placed on monitoring the accident experience of heavy-duty trucks as these systems begin to be deployed in the field (for example, as electronic stability control systems begin to penetrate the fleet). It is the role of the manufacturers to develop safety systems for commercial application. DOT can play important roles in (1) providing support for field tests (known to DOT as field operational tests), (2) monitoring field data to help substantiate benefit analyses used to prioritize resources, and (3) implementing regulations that would require the adoption of safety systems that were proved to be effective. With adequate field data, DOT should refine and more rigorously specify and prioritize goals for accident avoidance technologies.
