5 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)

26 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
