Evaluation of the impact of exclusive bus lanes on traffic in Tashkent

This study evaluates the impact of exclusive bus lanes on traffic in broader traffic networks over an extended timeframe. Using PTV Vissim to model existing traffic conditions, we introduced exclusive bus lanes and studied future traffic conditions considering a modal shift, as inferred from a binary logistic model developed using Stata. The findings reveal that, while exclusive bus lanes significantly enhance bus performance on designated streets, reducing travel time by 37%, they do not improve bus performance on other roads, as indicated by the unchanged levels of service (LOS) in the broader network. However, a modal shift analysis suggests a positive long-term effect on overall traffic, indicating that approximately 33% of car users may shift to using buses following the introduction of exclusive bus lanes. Origin-destination analysis revealed that exclusive bus lanes reduce intersection permeability, leading to congestion that varies based on the traffic flow direction.
