Abstract:
The Traffic Analysis Zones (TAZs) are considered
as the smallest spatial unit in transportation and landuse
modelling. In order to enhance the accuracy of a transportation
and landuse model, it is important to identify the correct TAZ
demarcation on ground. The transportation and landuse
modelling and planning professionals tend to consider the
administrative boundaries as TAZ due to the readily available
demographic data. Further, the accessibility and the road network
are not considered in TAZ demarcation and geographical
centroids have been considered as the trip origin or destination.
Therefore, it is a current necessity to identify a methodology to
demarcate a TAZ system, considering accessibility to the road
network and the factors affecting trip generation and trip
distribution. The objective of this research is to develop a method
to demarcate Modified Traffic Analysis Zones (MTAZ)
considering accessibility to adjacent road network, the
homogeneity of landuses and socio-economic parameters.
