Transportation
planning relies on traffic demand forecasting process. The conventional process
is impeded by extensive amount of socioeconomic data. One of the most
widely-used models which mitigate this problem is the TransCAD Model. This
model is rarely used in Gaza Strip for traffic demand forecasting, and most of
the practices depend mainly on a constant growth rate of traffic. Therefore,
the main objective of this research is to apply this model in Gaza City for
traffic estimation. This model estimates the origin-destination matrix based on
traffic count. The traffic count was carried out at 36 intersections
distributed around Gaza City. The results of traffic flow estimation obtained
from TransCAD are assigned to the Gaza maps using the GIS techniques for
spatial analysis. It is shown that the most congested area at present is the
middle of the city especially at Aljala-Omer Almokhtar intersection. Therefore,
improvement scenarios of this area should be carried out. The results of
calibration of traffic flow estimation show that the differences between the
estimated and the actual flows were less than 10%. In addition, network
evaluation results show that the network is expected to be more congested in
2015. This work can be used by transportation planners for testing any network
improvement scenarios and for studying their network performance.
