Drivers' perception of LOSs at signalised intersections

This study considers driver perception to assess further the level of service (LOS) at signalised intersections. Motorcycle riders and car drivers are the main focus of this investigation. Videos of different LOSs were pre-recorded and later presented to the respondent in the survey. An ordered probit model was used to estimate the effects of important factors on the driver's perception toward different LOSs at a signalised intersection. The results obtained from the model demonstrate that trip-, socioeconomic-, road-related characteristics (e.g., pavement condition, geometric design, traffic control), and weather conditions are all significant variables influencing the driver's perception towards different LOSs at a signalised intersection. Our results can provide a reference when planners and other authorities assess the LOSs at signalised intersections.
