abstract="Traffic incidents, whether due to accidents also create safety hazards on the freeway. To enhance safety and to provide assistance and security to motorists, District 12 of the Texas State Department of Highways and Public Transportation has been operating a motorist courtesy patrol on some Houston freeways. A questionnaire study and a cost- effectiveness analysis were used to evaluate the operation of the patrol. The questionnaire study indicated that motorists aided by the patrol were overwhelmingly in favor of continuation of the program. The cost-effectiveness analysis showed the patrol to have a benefit-cost ratio of 2 to 1. Several additional qualitative benefits are discussed.<p />",
