Building on previous research a conceptual framework, based on potential conflicts analysis, has provided a quantitative evaluation of ‘proneness’ to red-light running behaviour at urban signalised intersections of different characteristics. The results provided evidence that the commonly used violation rates could cause improper evaluation of the extent of the red-light running phenomenon. The application of the conceptual framework was then tested on a signalised intersection. Further investigations were carried out using a traffic micro-simulation model, to explore geometric design, traffic volumes and driver behaviour characteristics that significantly affect red-light running and thus to improve the prediction capability of the proposed potential conflict model. A degree of consistency in the measured and simulated red-light running was observed and the conceptual framework was shown to have promise. The microsimulation is at its early stages of the development. In a quest to deliver safer junctions future work will delve deeper into the geometric characteristics of the junction, traffic conditions and signal control which significantly influence the red-light violation.
