In this paper, the time series model, Autoregressive Integrated Moving Average (ARIMA) is used to predict bus travel time.
ARIMA model is simpler used for predicting bus travel time based on travel time series data (historic data) compared
to regression method as the factors affecting bus travel time are not available in detail such as delay at link, bus stop,
intersection, etc. Bus travel time prediction is an important aspect to bus operator in providing timetable for bus operation
management and user information. The study aims at finding appropriate time series model for predicting bus travel time by
evaluating the minimum of mean absolute relative error (MARE) and mean absolute percentage prediction error (MAPPE).
