ABSTRACT: Traffic congestion is a major problem faced by many cities across the globe. The drawbacks of such problem are much more severe in developing countries due to the weak enforcement of policies, and lack of infrastructures to handle congestion, among others. In this paper, an autoregressive integrated moving average (ARIMA) model is developed to analyse the traffic flow dynamics of the Philippines, which is a relatively under-explored area in the current literature. Results show that the model attains good predictive performance. Several scholarly implications are drawn out from such results. Above all, the results provide theoretical lenses with which traffic conditions in developing countries can be examined. Moreover, such results aid in streamlining strategies and initiatives for managing traffic challenges in developing countries.
