The application of gravity model to estimate the trip distribution of bus service passenger is presented. This model has been used in modeling such as freight transport, pedestrian, and vehicular transport. However, so far it has not been applied specifically in bus passenger trips distribution. To manage passenger trips and to improve bus system service, the passenger trips or bus service demand is necessary to be assessed. The analysis and assessment are performed for estimating the trip distribution each pair of origin and destination zone. In this case, therefore, a regular stage bus service operated in mixed traffic at corridor level, with long distance route, low loading passengers, and low level of service is assessed. Data was collected by performing on board survey include route distance, location and frequency of stopping, passengers of boarding and alighting. By using the passenger of boarding and alighting data, the gravity model is calibrated for estimating the bus passenger trip distribution. The result shows that the gravity model is applied appropriately to estimate bus passenger trip distribution. The model is helpful to estimate and to assess the trip distribution of bus service passenger each pair of sub zones. This contribute to a better management of passenger trips, the more reliable bus service, and other service operations.
