This study involves the analysis of commercial vehicles trip patterns in Klang Valley
using the Gravity Model which are singly and doubly constrained. For every type of
the Gravity Model, distance and travel time were adopted as the spatial separation
between the transport zones. The models were calibrated using observed origindestination
trip matrices of commerciul vans, lorries, trailer-lorries and trailercontainer-
lorries. This study demonstrated that doubly-constrained Gravity Model
synthesised the trip patterns more accurately forr both types of the spatial separation.
Trailer-lorries and container-lorries trip patterns are synthesised more accurately
using the travel time as the separation function. Unlike for other types of vehicles,
travel distance as the separation function in the Gravity Model synthesised more
accurately the trip patterns. In term of separation function, both the single and
doubly-constrained Gravity Models using power function were found to be better than
the exponential function for the three groups of vehicle i.e. heavy lorries, trailerlorries
and container-lorries. However the exponential function is better in
replicating the trip patterns of commercial vans and small lorries as this type of
vehicles are usually used for short distance hauling |
