Abstract
The eastern region of Nablus city has witnessed a remarkable development in terms of
governmental and private buildings during the last ten years. This has led to an increase in the
traffic flow presented by noticeable congestion.
Moreover, the same area also witnessing a large movement of pedestrians and vehicles with
the early morning and afternoon hours, since it connects eastern villages of Nablus with the
city. Furthermore, the existing of the government ministries which are distributed to three sites
in that area, in addition to a public park and more than ten schools, are all contributed in the
existence of traffic congestion in the area.
Furthermore, there is a desire from Nablus municipality to establish a commercial center and a
police station next to the Childhood Happiness Park (Isa’ad Al-Tuffolah). This area can
therefore be considered as one of the most city vibrant regions.
This development and vitality requires good traffic management, redesign some intersections,
and developing a future traffic plan. Also proposing a pedestrian traffic plan, where some
citizens and school students need to cross streets with a width of more than 30m in order to
reach their destinations.
In GP1, the team has studied the existing and the future conditions in the area with different
scenarios such as constructing a bridge and applying BRT system (Bus Rapid Transit). These
conditions are primary related to the Intersection Capacity Utilization (ICU) level of service,
which represents delay on intersections.
After data has been collected (inventory study and counting vehicles) and using Synchro 10
software, the team has selected the best scenario between studied scenarios, which was a
combination of changing some movements in the network, applying the BRT system and
applying the proposed bridge. This selection was chosen relating to the measure of
effectiveness report from Sycnhro 10 software, which gives the least delay and least emissions
between scenarios.
In GP2, the methodology included collecting data such as master plan and contours map from
municipality. Then the team has redesigned Othman intersection within the available Right of
Way (ROW) and designed the proposed bridge using two softwares, Infraworks and Autocad
Civil3D. For the overpass, a conceptual cost estimation per meter square of decade is proposed
for pavement and precast concrete.
Also, the team installed a traffic signal at the ministry of education intersection. The cycle
length was optimized by Synchro 10 software.
