Many problems in transport planning require an origin-destination (O-D) matrix to represent the travel pattern. The alternative of using traffic counts to estimate O-D matrices is attractive. The stressing of the research is to estimate unknown parameter of transport demand model by combining trip distribution, mode choice and route choice in single process. Furthermore, the factors affecting the accuracy of the estimated O-D matrices will be studied is the effect of incorporating errors in traffic count information and the effect of trip assignment techniques. Several important findings can be concluded as: (1). The convergence of () and () value depends on starting value of () and (); (2). Error in traffic count is not affecting the accuracy significantly, and (3). It can be finally proven that the use of equilibrium assignment in the trip assignment stage also gave significant impact compared to the use of all-or-nothing assignment.
