Multimodal and Corridor Applications of Travel Time Reliability

Five previous Florida Department of Transportation (FDOT) research projects on travel time reliability (FDOT Contracts BD545-48, BD545-70, BD54577 977-02, and BDK77 931-04) developed tools for annual freeways, to assist in the project prioritization and selection process. However, there is also a need to use these tools for annual reporting to the Legislature. To accomplish this, the tools should be able to provide all performance measures related to travel time reliability that are of interest for these purposes. Furthermore, they need to provide travel time reliability measures for the arterial portion of the Strategic Intermodal System (SIS) and also consider reliability across all modes (including the auto, rail, transit, etc.) Therefore, this research project made improvements in the freeway travel time reliability method, developed a new arterial travel time reliability method, and proposed a framework for considering travel time reliability in a multimodal context. Improvements in the freeway travel time method include the inclusion of two additional performance measures, the Travel Time Index (TTI) and the Planning Time Index (PTI) to estimate reliability. Also, an improved method for evaluating weather effects was developed and incorporated into the calculations. Arterial travel time estimation models were developed using the simulation program CORSIM, considering a total of 1200 scenarios. A spreadsheet similar to that previously developed for freeway sections was developed to obtain travel time reliability measures along arterials, based on the results of the developed travel time estimation models. Lastly, a conceptual framework for conducting multimodal travel time reliability analysis was developed considering single mode travel and multiple mode travel.
