Evaluation of Centre Line Marking on Driver Behaviour

Road crashes are one of the main topics of discussion in the field of transportation nowadays. Studies have proved that driver behaviour is a contributing factor in over 90% of road crashes. As a result, it is required to identify how the driver behaviour varies with safety improvement measures to reduce crash rate. One of the safety improvement measures is delineation of paths for vehicle movement using road markings. The effect of centre line marking on drivers is investigated by studying the position of vehicles on two-lane two-way highways, both at straight sections and at horizontal curves, using a before-and-after study. Data were analysed using tools like traffic distribution analysis, conflict energy distribution, scatter plot analysis and ANOVA test. From traffic distribution plots, it is found that at most of the locations, vehicles that move through the centre of the carriageway shifted their path towards their own lanes after centre line marking was drawn. A linear trend is observed between speed and lateral position of the vehicles. The significance of each vehicle type with respect to speed and lateral position at particular lateral position ranges and speed ranges respectively were also analysed, and in most of the cases, it was found significant. Finally, model was developed for estimation of lateral position of vehicles. The data and analysis results can be used for road safety analysis, identification of improvement measures, as an input into the microscopic traffic simulation models and for developing local logics aimed at advanced driving assistance modelling (ADAM).
