The Potential for Premium-intermodal Services to Reduce Freight CO2 Emissions in the Quebec City - Windsor Corridor: A Stated Preference Application

86th Annual Meeting of the Transportation Research Board, Transportation Research Board

January 23, 2007

The Quebec City-Windsor corridor (the Corridor) is the busiest and most important trade and transportation corridor in Canada. The transportation sector is the second largest greenhouse gas (GHG) emission category in the country. This paper develops estimates of the potential for CO2 emission reductions in the freight transportation sector through the use of premium-intermodal services between the main Corridor destinations. CO2 reduction estimates are arrived at using a Stated Choice methodology. The basis of the analysis is a recently administered stated-preference carrier-choice survey of shippers in the Corridor. Survey data were used to develop mode share models for five different categories of shipments between eighteen city-pairs. A railyard-catchment approach was taken to arrive at estimates of contestable intercity truck traffic using a subset of the Ontario Ministry of Transportation’s Commercial Vehicle Survey. CO2 emissions were based on current truck traffic estimates, and emissions factors obtained from MOBILE6.2C. The results show that premium-intermodal has the potential to capture a significant share of traffic between the main Corridor destinations with potential CO2 emissions reductions considered to be in the range of nil to 0.4 Mt.
