Description

This paper analyzed the widely-used access management treatment in Rawalpindi/Islamabad, Pakistan: using U-turn instead of traffic signal or direct right turn. Data was collected from a very congested traffic signal at Khanapul traffic signal, Islamabad. The traffic signal was recently closed and traffic was diverted to newly constructed U-turns placed at downstream. Level of service, delay travel time and emissions were computed for both scenarios using Vissim and Synchro 9. It was fund that the provision of downstream U-turn was effective in reducing the delay and improving traffic operation.
