The operational efficiency of any traffic facility including that of a signalized intersection is indicated by the Level of Service (LOS). The method recommended by Highway Capacity Manual for signalized intersection LOS analysis uses delay as the service measure and does not incorporate the users’ perception. As LOS is a measure of customer satisfaction, it is important to incorporate the users’ perception into LOS analysis. In this framework, an extensive user perception survey has been carried out at three intersections in Gujarat, India. Using a sample of 1170 respondents, this research studies how the users perceive the LOS at signalized intersections. Importance-satisfaction analysis was carried out to identify the most important and satisfying factor. Through the analysis, the authors found out that the waiting time at the signal followed by the pavement surface quality are the most important and least satisfied factor by the users. By estimating the ordered probit model, authors found that users not only consider delay but also considers a multitude of factors while evaluating the LOS perception at signalized intersection.
