• Abstract:
  The Western Transportation Institute (WTI) conducted research on behalf of the Colorado Department of Transportation ; (CDOT) to study the cost effectiveness of existing CDOT FAST systems. Both the national survey and the CDOT survey ; confirm the need for significant maintenance activities to ensure successful operation of FAST systems. Safety analysis of ; CDOT FAST system reveals a reduction in the number of annual crashes on multilane rural highways by 2 percent, urban ; interstates by 16 to 70 percent, rural interstates by 31 to 57 percent and interchange ramps between interstates by 19 to 40 ; percent. Overall, CDOT FAST systems included in the analysis have reduced crash severities at many sites resulting in ; potential safety benefits of $196,428 per winter season during the “after deployment” study period. Further, a benefit-cost ; excel sheet was developed based on the estimated crash reductions observed for each of the different roadway types. ; Implementation ; The study found that FAST systems have demonstrated the potential to reduce the number of crashes and reduce the cost of ; winter maintenance activities, if sited at appropriate locations (e.g., high-traffic-volume ice-prone ramps). However, ; improved installation techniques and involvement of maintenance crews during FAST installation are necessary to further ; increase the cost-effectiveness of a FAST system deployment. Extra effort will be made in sharing the information gained ; from this research study by focusing on CDOT personnel involved in planning, design, construction, operation and ; maintenance of FAST systems.
