  • Abstract:
    Previous research funded by Florida Department of Transportation (FDOT) developed a method for estimating ; travel time reliability for arterials. This method was not initially implemented or validated using field data. This ; project evaluated and refined these initially developed models using field data, and implemented them on the arterial ; portion of the Strategic Intermodal System (SIS). The research team first implemented and evaluated the ; previously developed travel time estimation models using data from four selected arterials in Jacksonville, ; Florida. Field travel time data for the four selected arterials was collected through a BlueTOAD database. ; The comparison between the model estimated travel time and field data showed that the original models ; greatly overestimated arterial travel times. Thus, a new set of models was developed using CORSIM, and ; it was concluded that the newly developed models provided travel times that are closer to the field data for ; the four arterials studied in this project. Using these revised models, a 2011 statewide arterial reliability ; database was developed to obtain reliability performance measures for all arterials in the SIS. The results ; were aggregated by county and provided in this report. Travel time reliability results are also provided for ; SIS arterials in the vicinity of major ports and airports in Florida.
