A COMPARISON OF SOME STATISTICAL TECHNIQUES FOR ROAD ACCIDENT ANALYSIS

At the TRRL (Transportation Road Research Laboratory)/SWOV (Institute for Road Safety Research, The Netherlands) Workshop on Accident Analysis Methodology held in Amsterdam in 1988, the need to establish a methodology for the analysis of road accidents was sated by all participants. Data from different countries cannot be compared because there is no agreement on research methodology, data collection, and analysis. This paper discusses the background of linear and log-linear models used to analyse accident data, and the model assumptions. Two relevant and fundamentally different classes of models exist. They are called design oriented and object oriented models. Two different types of generalized linear models, both object-oriented, are used by SWOV and TRRL. The qualitative data analysis models used at SWOV are primarily descriptive and useful for model exploration. The generalized linear interactive modeling technique used at TRRL has stricter assumptions, but is better suited for model testing. In order to compare these models, a number of analyses were carried out on roundabout data from TRRL.
