Presentation Transcript

  1. Traffic Engineering with VISUM Modeling of Parking Lot Utilization, Walking & Gender Specific Travel Behavior at a University Mike Hafner, PE and Sara Senger, TEC Engineering Inc.; Ed Hayes, PTP and Chetan Joshi, PTV America Inc.

  2. Outline • Data and network • Transportation facility coding • Transportation analysis zones • Evaluation and results • Private transport systems by time period throughout the day • Public transport sketch planning using TSys • Modeling of the university parking lots • Wandering algorithm…a way to evaluate ITS solutions and mimic parking behavior in a demand model

  3. Data and Network: Overview • Roads and intersections coded by TEC and PTV • Special link and node types • Access to on-campus pedestrian from automobiles available only through parking facilities adjacent to campus • Portions of campus segregated from automobile travel

  4. Data and Network: TAZ • Transportation analysis Zone definition • Small zones for discrete modeling of origin and destinations from individual buildings

  5. Data and Network: Coding Conventions • Development of walking and drive-walk demand using Python scripting process • Special network coding to allow for a transition from drive to walking in the university model

  6. Evaluation and Results: Input and Method • Trip matrices broken down into hourly time periods during the school day • Distribution based on data available from survey

  7. Evaluation and Results: Time of Day Parking Analysis

  8. Assignment • Private transport assignment by time period throughout the • Public transport assignment by transport system for sketch Screenline Objects

  9. Parking Lot Demand • Problem: Drivers with imperfect knowledge search for parking spaces and increase local circulation around lots • Solution: Modeling of additional parking lot circulation using Python scripting
