POLICY SENSITIVITY ANALYSIS OF KARACHI COMMUTERS

An incremental logit model was used in order to measure the change in behavior of commuters after the introduction of the newly proposed transport mode of magnetic train. Car, motorcycle, paratransit, bus, and coach were existing transport modes, while magnetic train was considered to be a future mode. Both direct and cross elasticity were calculated for existing and future conditions of Karachi. For RP data models, it was revealed that total travel time variable had higher direct elasticity of -1.017 for bus, while total cost divided by family income variable had higher effect on the cross elasticity of car, motorcycle, and paratransit. Additional findings are also given and discussed.
