Queensland University of Technology is currently conducting an assessment
of the impacts of heavy vehicles on urban traffic.
Specifically, we are investigating the effects that large combination
vehicles, or LCV's (such as Road Trains and B-doubles/B-trains) have on the
traffic flow, capacity and delay throughout an urban network or corridor.
Significant work has been conducted on rural and remote area operations of
LCV's. However, it is in accessing urban freight facilities that
considerable productivity gains can be achieved - often at the expense of
increased traffic congestion around the vehicle.
The initial literature review is under way and we are looking for
information on previous or current research into this area.
Information and references relating to computer-based microsimulation of
traffic would be particularly useful. We are finding that many current
traffic simulation models do not accurately represent the turning,
acceleration/braking and gap acceptance criteria for LCV's, and hope to
achieve a methodology for including such effects into traffic simulation
models.
Any information would be greatly appreciated.
