This study explores the usage of trajectory data for delay estimation at signalized intersections. With increasing traffic and restricted road space, urban traffic corridors are experiencing increasing congestion. Traffic signals are deployed to efficiently help the traffic to navigate through the nodes. The measure of effectiveness of signalized intersections is measured in terms of delay. Several methods and approaches are available to compute the control delay caused due to intersection. But while studying the operational efficiency and analyzing the safety aspects at signalized intersections, many times different methods and measures are employed for data collection responsible for collecting different dataset. But, development of trajectory data for study section enables us to study all the aspects concerning operations and safety with single dataset. A quick delay estimation method based on the trajectory data has been proposed and based on the literature study; six of the most commonly used delay estimation methods have been used. The results from six methods are then compared with the results of delay estimation from trajectory data. In addition, the shortcomings of the commonly used methods have been discussed in the result section.
