The purpose of the study was to develop a simulation model that represents urban bus operation on signalized arterial streets. The model is to be used as an evaluation tool in the formulation of new schemes to improve bus service in urban areas. To pave the way for the development of such a model, two basic relationships in urban bus systems were investigated. They respectively involve: (1) the time required to load and unload a certain number of passengers and (2) the bus speed and acceleration characteristics. The model developed was named 'SUB' (Simulation of Urban Buses) and its program written in FORTRAN language. Traffic is simulated on the model by groups of vehicles that are processed at constant time intervals. Buses, on the other hand, are represented individually and processed only when significant events occur. The model has been calibrated in Washington, D.C. verified and subjected to sensitivity tests.
