摘要：AbstractTraffic planning should focus on the promotion of public transport to ensure sustainability. Buses have a vital role to play in this as they optimize the use of limited road space by carrying more passengers, compared to personal vehicles. This study is aimed at systematically simulating the impacts of various bus priority measures with respect to existing conditions by evaluating travel time savings, various traffic performance indicators and reliability benefits to address transportation challenges such as delays. The results obtained from the developed simulation experiments in VISSIM and the comparison with the field traffic behavior confirmed that the developed models accurately represent the actual traffic nature with less than 10% margin of error. The evaluation of the validated bus priority models showed that the priority schemes reduce bus delays by a minimum of 21.32% at intersections and some of the strategies can easily be incorporated with less investment. Because of the simulated priority attributes, the modal shift assessment result showed that 62% of other mode users have high tendency to shift to buses; except for private car users in which 66% of the users have low mode shifting interest. Policy makers and transport planners should implement priority measures to reduce delays, improve service management and reliability, as they are low-cost with highly efficient traffic management that keep buses moving and boosting mobility in areas that attract many people.
