Abstract
In this work we have applied a methodology consisting in a Bayesian hierarchical modelling and EWMA Charts for the evaluation of the trend of accident rates in a transportation corridor in Spain. We illustrate how to identify trends or patterns in the average (joint set of segments of the corridor) and specific (individual) segments of different interurban roads using annual observed accident frequencies; we also derive the predictive density function for future observations.
