• Abstract:
  Intermodal transportation
  
  system planning, design,
  
  improvement, performance
  
  evaluation, or economic
  
  assessments include safety
  
  improvements because they
  
  lower the overall cost of
  
  transportation. State Departments of Transportation (DOTs) are charged with the development
  
  and implementation of Strategic Highway Safety Plans (SHSP) as required by law. SHSPs have
  
  broader impacts on passenger and freight transportation to the impact on the overall cost of the
  
  transportation system. Many states’ SHSPs, as Louisiana’s, include an infrastructure focus area
  
  that addresses the locations of the majority of serious injury and fatal crashes, specifi cally
  
  intersections and roadway departures in the vicinity of curves. The Federal Highway
  
  Administration (FHWA) Highway Safety Improvement Program (HSIP) states, “Intersection
  
  safety is a national, state, and local priority. Intersections represent a disproportionate share of
  
  the safety problem.” As a result, private and public organizations are devoting resources to help
  
  reduce the problem. Louisiana has previously been recognized as a “focus” state for intersections
  
  by the FHWA, which was the result of a number of factors, including a higher than the national
  
  average of crashes at intersections. Subsequently, Louisiana’s SHSP implementation strategy
  
  calls for the “aggressive deployment of low cost safety treatments in a systematic manner based
  
  on both historic data and roadway characteristics.” Many states are at a similar stage of their
  
  deployment of the SHSPs and have the same problems with respect to intersection crashes and
  
  road departure crashes. Thus, evaluating road safety improvements is a common challenge
  
  among all state DOTs. To assess the eff ectiveness of the deployed improvements, a system is
  
  required that includes a data-tracking capability and an analysis tool. Therefore, a decision
  
  support system that incorporates the principles of the recently published AASHTO Highway
  
  Safety Manuel (HSM) is needed to allow a timely collection of road improvement data and the
  
  evaluation of the safety benefi ts of these improvements.
