Multilevel modelling and time series analysis in traffic safety research : methodology. SafetyNet, Building the European Road Safety Observatory, Workpackage 7, Deliverable 7.4.

This deliverable gives the theoretical background for the two families of analyses, multilevel and time series analysis. For each technique the objectives, detailed model formulation, and assumptions are described and subsequently the technique is illustrated with an empirical example relevant to traffic safety research.
