Assessing Travel Demand for Exclusive Truck Facilities Matthew Roorda, University of Toronto Michael Hain, University of Toronto Glareh Amirjamshidi, University of Toronto Rinaldo Cavalcante, University of Toronto Baher Abdulhai, University of Toronto Clarence Woudsma, University of Waterloo Funding Agencies – Infrastructure Canada – IntelliCan Transportation Systems METRANS National Urban Freight Conference 2009 – Oct 21-23, 2009
Presentation Overview • Research Goal and Objectives • Rationale for Exclusive Truck Facilities • Background • Modelling • Preliminary Results
Research Goals • Assess the potential for highway lanes that are specifically designated for truck travel • Develop tools and methods for assessing benefits and impacts.
Scope and Study Boundaries 65 km 30 km 90 km 160 km
Rationale for Exclusive Truck Infrastructure • Mobility • Over 30,000 trucks/day on some segments of Hwy 401 and QEW • Economic value of goods > $1B/day • Safety • Trucks involved in 9% of all vehicle collisions • Collisions involving trucks result in 20% of all fatalities • Productivity (Longer combination vehicles) • Infrastructure Cost (Pavement damage) • Revenue Generation (Tolled truck lanes)
Background • Existing Truck Facilities • New Jersey Turnpike dual-dual section • Los Angeles I-5 Truck Bypass Lanes • South Boston Bypass Road • Clarence Henry Truckway, New Orleans
Los Angeles I-5 Truck Bypass Lanes • Barrier separated, limited access • Interchange bypass
Background • Corridors Recently Studied • Trans Texas Corridor • Metro Atlanta • SR 60 in Southern California • I-4 Crosstown Connector – Tampa • I-710 Truckway LA • I-81 in VA • Dallas

Some Model Results • Base case • Values of time: $60/hr light trucks; • $120/hr for medium and heavy trucks • A) Convert one lane to exclusive truck lane on Hwy 401 • <5 min (7.5%) additional delay for cars (along Hwy 401) • 13-21 min (22-33%) savings for trucks (along Hwy 401) • 150-750 vph in the truck only lane • B) Exclusive Truck Lanes in Hydro Corridor parallel to Hwy 401 • 1 min (1.5%) savings for cars (along Hwy 401) • 3-10 min (5-15%) savings for trucks (along Hwy 401) • 17-26 min (20-30%) savings for trucks (along Hydro corridor) • 100-800 vph in the exclusive truck lanes
Microscopic Traffic Simulation • Refining travel time/speed estimates • Car following, lane changing, queuing • Detailed freeway routing • Conflict Analysis • Rear-end conflicts • Lane-changing conflicts • Merging conflicts
Microscopic Traffic Simulation Captured bottlenecks along freeways
