Best practice
One of the main objectives of SafetyNet is to develop a best practice for analysis of linked data, more precisely for the analysis of the combination of accident data with exposure data and/or safety performance indicators. Analysis of such complex datasets is not always as straightforward as one might think it is. Several issues related to complex dependencies in time and space come into play.
The best practice for analysis of complex road safety data structures is provided in two inter-connected SafetyNet reports on the subject:
These two reports provide best advise on how to chose and apply statistical techniques that are part of two broad families of data analysis: Multilevel Modelling which is dedicated to the analysis of hierarchically structured data, and Time Series analysis which is dedicated to overcoming dependency-issues in time-related data.
