Abstract:
Manufacturing and distribution systems have undergone significant changes
in recent years; "just-in-time" production and distribution systems
have led to an increase in the number of time-sensitive freight movements. Time-definite
services and regular updates on the status of en-route shipments is expected
of many shippers. Additionally, freight movements take place in smaller units,
increasing overall freight movements. This study extends an earlier study of
the trucking industry in California by focusing on the impacts of shipper decisions
on performance of the highway transportation system. Information will be gathered
using both stated preference and revealed preference survey techniques. Forecasts
of future freight transport growth will be developed and of likely changes in
the configuration of the freight network in southern California.
Key Words: freight demand modeling, commercial vehicle operations, urban
goods movement, shipper behavior
Work to Date:
We began with an in-depth examination of the 3rd Party Logistics Industry. This examination is detailed in
A. C. Regan and J. Song (2001), An Industry in Transition: Third Party Logistics in the Information Age, CD Rom proceedings of the 80th meeting of the transportation research board
and
J. Song and A.C. Regan (2001), Transition or Transformation? Emerging Freight Transportation Intermediaries, Transportation Research Record, in press.
We developed two surveys for 2001 deployment. The first is a survey of the trucking industry competed in June 2001. We are examining those data now. We have three working papers and expect to have these finished by the end of September.
The second survey is of the 3PL industry.
