Dynamic Transit Trip Planner (DTTP) (Interactive Transit Station Information System [ITSIS])

Although public transit is an important means of transportation for many American travelers, it is still largely underutilized. Encouraging greater transit use is seen as part of the integrated solution to the congestion problem in metropolitan areas and has been a major objective for transportation innovations such as Integrated Corridor Management (ICM). The real-time transit traveler information system (TTIS) has been one of the key innovations to enhance the user experience and encouraging mode shifts. Effective TTIS solutions have already been implemented worldwide and are providing essential core travel information to users, empowering them to make better transportation choices. While this information is typically still provided to travelers using dynamic messaging signs (DMS) at fixed locations, recently, it is becoming more common for it to be made available through the internet (website) and personal mobile devices (e.g., smart phones) with enhanced connectivity applications installed on them (FTA, 2011). In some cases, real-time information is simply “pushed” to interested individual users without the need for significant user input. However, this project looks at moving to a more robust interactive system there exist several technical gaps in the current implementation of TTIS that must be overcome. These can generally be grouped into three major categories.
