A transportation system to move students, faculty and staff on a university campus and its surrounding community continues to be an unmet need for most North American universities. In this study, a multi-modal travel demand was developed to model the travel demand of students, faculty and staff in various transportation scenarios on a university campus and its surrounding community. The modeling methodology has several innovative characteristics, which adapt the model to a university setting and differentiate it from traditional travel demand models, including: (1) Individual trip generation and trip distribution information, such as class schedule, residence addresses, office addresses, etc., were used to construct student, faculty and staff trip tables; (2) a multi-modal transportation network was constructed that reflects the necessary interaction among motor vehicles, pedestrians, parking facilities and public transit facilities; (3) A time-of-day model that uses probability distribution functions (PDF) to simulate temporal distribution of trips was developed to realize the incremental trip assignment. The model was used to evaluate an existing transportation system and two alternatives, each with a Personal Rapid Transit (PRT) system assumed constructed on the Kansas State University (KSU) main campus. A multi-measure evaluation approach was developed to evaluate the mobility impact of the transportation alternatives examined. |
