• Abstract:
  This evaluation of the Motorist Assist (MA) program in St. Louis estimated that MA has an annual benefit-cost ratio (B/C) of 38.25:1 using 2009 dollars. This estimate was based on nationally accepted AASHTO methodology and was based on 1082 secondary crashes reduced per year and an average crash value of $72,350/crash. This B/C is an astonishing figure that is larger than all of the B/Cs reported in literature for other similar freeway service patrol programs. One factor that contributed to this B/C was the large secondary crash reduction ratio estimated using actual data from the years prior to and after MA was first deployed in 1993. Other factors include the low cost of operations and the high cost of secondary crashes. MA is a critical component of an overall Traffic Incident Management (TIM) strategy. Responders, such as the police, validate this perspective by commenting that MA is better equipped to handle traffic control, which allows the police to take other actions such as investigating the incident. The evaluators recommend for MA to be strengthened.
