Toronto International Research Experience

Joshua Auld

September 22, 2008

Foreign Experience Overview Spent 30 days in Toronto, Ontario

June 14 – July 14 Stayed at a short-term (1 month) condo rental

Worked at the Sandford Fleming Engineering Building at the University of Toronto

Collaboration with the ILUTE project team in the Transportation section of the Civil Engineering Department

Attend ILUTE project meetings, seminars, weekly discussions, etc.

University of Toronto

Largest University System in Canada 63,000 undergrad, 10,000+ graduate

Public research university On of the top non-U.S. universities in the world

Three campuses – main campus is St. George

Surrounds Queens Park – large downtown park and regional government complex

ILUTE Project

Project team run by Professor Eric Miller consisting of many grad/undergrad students and several other professors

Developing an Integrated Land Use Transportation and Environment microsimulation model

Comprised of a number of different sub-models: Land Use – auto ownership, location choice, etc Transportation – TASHA scheduling model, trip assignment Environment – currently working on this stage, integrating

Mobile6 with assignment results

Areas of Collaboration - Scheduling

ILUTE microsimulation includes the TASHA scheduling model Developed by Prof. Matt Roorda Generates activities randomly Schedule them into project/activity schedules

according to a system of rules Resolve conflicts/adjust schedule to fit

Areas of Collaboration – Scheduling (cont.)

Worked with Matt Roorda on updating scheduling rules

Include results of conflict resolution model

Make more general set of scheduling rules

Paper submitted to TRB for publication

Conflicting Activity

Any Combination of Deleted or Home/Null Activities

TASHA CONFLICT CASES

NEW CONFLICT CASES

Note: Activities with a type listed indicate that only a conflict with the given type will be considered. New conflict cases exclude all situations with more than 1 activity entirely overlapped.

Areas of Collaboration –GPS surveying

Currently implementing a GPS survey – TRIPS Under development for a number of years Much effort in designing survey Automatic link matching, mode finding, etc.

Advised on equipment/technical issues

Discussed and compared survey methods

Testing - Side-by-side comparison of survey results

GPS surveying, cont.

Work summary

One and possibly more publications relating to activity scheduling Potential of implementing new system in TASHA

Dr. Miller serving on thesis committee Advising on dynamic activity modeling

Continuing discussions on GPS surveying Also visited Dr. Sean Doherty – detailed

discussing of survey techniques
