Simulation of the City Bus-Driver System With Small Computers 785090

It is possible to measure the operating characteristics of buses by direct, experimental measurement, but this approach is difficult and expensive. Simulation models offer preferable means of evaluating buses for civic operation, especially in design stages; the paper studies how different aspects of operation can be initially determined for incorporation into a model suitable for computer processing.A simulation model must include mechanical, vehicle parameters as well as influences of external factors, such as passenger loading and length of routes. Particular attention is given the latter factors; the bus line of Budapest is used as an example of how bus routes, loading patterns, operational speeds, etc. can be analyzed. These analyses draw on both empirical data (such as current bus schedules) and theoretical considerations (engine-dependent parameters, hypothesized boundary values).A simplified flow sheet for computer processing is presented. Measurements show that this approach offers good approximation of actual operations.
