Transportation leadership you can trust. presented to 13 th Transportation Planning Applications Conference presented by Thomas Rossi May 10, 2011 Integration of an Activity Based Model, Traffic and Transit Simulation Models, and MOVES

SHRP Project C10 Partnership to Develop an Integrated, Advanced Travel Demand Model and a Fine- Grained, Time-Sensitive Network 1

2 SHRP C10B Team Cambridge Systematics, Inc. Sacramento Area Council of Governments University of Arizona University of Illinois, Chicago Sonoma Technology, Inc. Fehr and Peers

3 Project Goals and Objectives Improve modeling process to address policy and investment questions Facilitate further development, deployment, and application of procedures Make operational an advanced travel demand model integrated with a fine-grained, time-dependent network

4 Secondary Objectives Produce a portable, transferable product Incorporate products from related SHRP projects Incorporate travel time reliability into the modeling capabilities Demonstrate the application of outputs of the integrated model to estimate greenhouse gas emissions using MOVES Demonstrate the dynamic integrated model set in a real- world environment on selected policies

5 Integrated Modeling Approach

6 Integrated Modeling Approach (continued)

Model Integration Issues From Model Design Plan Use of tour information in the traffic simulation Obtaining departure time profiles Distributed values of time, and other information about travelers Transit vehicle run information Network skimming process and feedback of travel times Data management across integrated model components 7

Activity Rescheduling 8 Preplanned Schedule made previously Initial Decision Process Rescheduling Module Final Preplanned Schedule for time t Change in network condition Change in activity attributes Rescheduling? N Y t=t+1 Updated preplanned schedule for time t

Variable Value-of-Time Escort Tours
