Abstract:
Focusing on the optimal redesign and analysis of congested intersections, specifically
examining the Kernal Sher Khan Shaheed Road (KSKSR) in Islamabad. Due to its
strategic importance and increasing traffic volumes, the KSKSR has experienced
significant congestion, leading to delays, increased vehicle operating costs, and negative
environmental impacts. The project employs traffic simulation modeling using PTV
VISSIM software to evaluate the current operational conditions and propose alternative
solutions for improving traffic flow and reducing congestion. The study encompasses key
intersections along the KSKSR, analyzing both pre- and post-rehabilitation scenarios to
assess the effectiveness of recent improvements implemented by the Capital
Development Authority (CDA) and the National Logistics Cell (NLC). By comparing
these scenarios, the project aims to provide evidence-based recommendations for further
enhancements, including potential changes in U-turn locations, safety measures, traffic
efficient measures like Actuated Signals, Protected Phasing etc. The findings indicate
significant improvements in traffic flow, reduction in congestion, travel time at the
studied intersections, demonstrating the value of simulation-based analysis in urban
traffic management. This research contributes to optimizing urban transportation systems,
ultimately enhancing mobility and quality of life for residents and commuters of
Islamabad/Rawalpindi.
