A general linear model framework for traffic conflicts at uncontrolled intersections in greater Cairo

• Combined with other data sets, the traffic conflict technique is an efficient tool for analyzing traffic safety problems at specific sites. The objectives of this paper are to identify the roadway variables that affect traffic conflicts at uncontrolled intersections in greater Cairo, and to develop mathematical models of conflict rates with the road variable. Alternative statistical methods of analysis based on the general linear model framework are discussed. This framework provides a flexible range of statistical models for representing response of mean conflict rates on design variables of interest and for selecting the distribution of conflict rates within individual classification cells. A special field survey was launched to collect data required for model calibration. Provision of some significant countermeasures for improving road safety levels are presented.
