Abstract
The classic approach to the construction of a mathematical model
to simulate traffic movements in a dense road network, such as a
Central Business District (CBD), includes the need to prepare a
complete Origin - Destination (O-D) matrix of vehicle trips into
and through the network. Subsequent steps in the model deal with
the coding of the road network and the assignment of the 0-D
matrix onto the network.
The acquisition of reliable origin - destination data to create
the 0-D matrix is very often a tedious and costly exercise The
use of traffic count information as an alternative method of 0-D
data creation needs consideration.
Using the Simulation and Assignment of Traffic in Urban
Road Network (SATURN) suite of computer programs, the task of
simulating the prevailing traffic conditions may be considerably
facilitated and hence reducing the cost of a traffic study in a
CBD area.
The present project report deals with that particular issue in
the context of a small CBD in South Africa. The results show
that saving can be achieved in the data collection.
