Introduction Nablus is one of the largest Palestinian urban areas
with its important sites. Moreover, it’s ahead quarter
of the largest Palestinian university.
Nablus city, one of the main commercial centers in the
West Bank.

The main locations that we have in the project are
The combined intersection which consists of two intersections, the first one is As-Salam Mosque intersection and the intersection of Hamdi Kanaan Street with Prince Mohammad Street.
Entrance of West Nablus Complex for shared-taxis to cities. Al- Arz intersection. Western Entrance of Nablus Municipal Complex. Intersection near the Entrance of West Nablus Complex for
shared-taxis to villages.
Intersections traffic manual count studies

Video recording supplementary traffic studies
• The team will supplement the manual intersection counting with video recordings
![Page 16: Introduction Study area Existing problem Objective Methodology Results and Conclusions Recommendations.](https://reader038.fdocuments.us/reader038/viewer/2022110213/5697bff01a28abf838cbac87/html5/thumbnails/16.jpg)
The locations of cameras

The team conduct the level of service analysis in order
to evaluate the performance of the intersections.
the team use HCS program in order to determine the
level of service at specific intersections.
Level of service an analysis studies

Synchro is used to provide traffic analysis, optimization, and simulation applications
Traffic simulation

Data AnalysisThe collected data are used to calculate :
Peak Hour(PH) Peak Hour Volume (PHV) Peak Hour Factor (PHF) Percent of Heavy Vehicle (HV) Determining vehicle classification of through and turning
movements at intersections.
These data used to determine the level of service
![Page 20: Introduction Study area Existing problem Objective Methodology Results and Conclusions Recommendations.](https://reader038.fdocuments.us/reader038/viewer/2022110213/5697bff01a28abf838cbac87/html5/thumbnails/20.jpg)
Growth factor The team use this equation to determine the growth factor
Vf =Vi (1+r) n
Then the value of growth factor value =4.49 %
This value used to predict the volumes in the study area after five years.

Design Criteria For a design speed of 50 Kmph
Super elevation (e)=4%
Friction factor (f) =0.155
Minimum horizontal radius =101m

Proposed Solutions to Solve Study Area Problems
Building an underpass (tunnel) which connects Haifa Street with Hamdi Kanaan Street.
Proper separation shared taxis that enter and exit Nablus Municipal Complex.

Design of proposed separation
• The team designed the separation lane in order to facility the movement of vehicle and pedestrian and to reduce the congestion in the vital street.

Recommendations Transfer the West Nablus Complex for cities and West Nablus
Complex for villages and examine the use of these sites for parking.
Another solution recommended is change Al-Jed intersection from unsignalized to signalized intersection because has a high traffic volumes.
