Abstract

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 redlight 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
