Effect of operation policies on dwell time

FROBSS (Fixed Route Bus Simulation System) simulation model is used to evaluate the performance of the routes. Five routes have been selected from the network of the General Company for Passenger Transport (GCPT) in Baghdad. Field data regarding these routes have been collected through field survey during March, April, and May of 2001, by using special field data sheets. These data have been input FROBSS, and the evaluation results indicated some problems on these routes such as long waiting time of passengers at bus stops, inadequate in addition to the most affecting problem which is the long journey time. Different operation policies are investigated in this paper to improve the performance of public bus system. These are considered: 1)Bus headway, 2) Bus design, and 3) Skipping bus stops.
