Abstract Poor service quality is one of the major causes for declining share of buses in urban India. Improvement of bus travel time by implementing bus priority measures at intersections is well regarded as an effective instrument to improve bus service by reducing the travel time. However, only a few research works have been reported in the literature on bus priority strategies in Developing countries such as India. This paper documents an experience of using micro-simulation software VISSIM© to evaluate the impact of providing Queue Jump Lane (QJL) as a bus priority strategy for three representative four-arm isolated signalized intersections in Kolkata, India. The study shows that QJL is expected to be beneficial even in a heterogeneous traffic environment that is prevalent in Indian scenario. The effectiveness of QJL is found to be influenced by various factors such as traffic volume, vehicle composition and road geometry. The study encourages further investigations in terms of validation of results based on field implementation of QJL and identification of the domain of applicability of QJL in signalized intersections of urban India.
