This document analyzes transportation issues along a corridor in Nablus, Palestine from Al Kindy Secondary School to Al Badawi intersection. Data was collected on traffic volumes, patterns, and levels of service at intersections. Two intersections were found to have unacceptable level of service after 5 years. Installing traffic signals at these intersections is recommended to improve traffic flow and reduce congestion along the corridor.

importance due its location as an economical and educational center of the
north sector of the West Bank.
