Abstract
The road network, which forms the backbone of the transportation system in the Palestinian territories, suffered seriously from damage and difficulty of use. A clear example on an important part of this network is the bypass road around Jenin city. The importance of the bypass road comes from connecting the Nazareth Street with Az-Zababida village passing throw many intersections. These intersections serve several villages such as Al-Jalama, Arrana, Deir Ghazala, Beit Qad, Deir Abu Daif, Aba, and Umm At-Tut. Furthermore, this road serves the Arab American University and Haddad Tourism Village because it facilitates the arrival of people coming from the occupied lands in 1948, through Al-Jalama crossing. The road will serve Tubas city and the near agriculture areas by transferring their crops to Al-Jalama crossing in order to export them to the occupied lands in 1948 instead of going to Tulkarm or Qalqilia. The road is classified as a rural-arterial road. It is a two lane paved road and it, similar to many Jenin roads, lacks basic safety requirements and it is in a relatively in bad condition. The road experiences several distresses, which causes structural and functional failure of the road. Another problem is the bad drainage conditions of this road, which often causes flooding on the surface of the road or in other cases the drag force of the water makes large holes beneath the surface of the road leaving the pavement suspended in the air in a dangerous way. This project studied the road focusing on the evaluation of its existing condition and go through geometric design issues based on AASHTO standards and exploring its future prospects. The study also include some traffic studies based on Manual of Traffic Studies and the Highway Capacity Manual, and pavement design based on AASHTO design procedure. The expected outcome is a new design of the road including the expansion and the changing of the alignment of the road, if needed, a solution for the drainage problem, and a proper design and traffic control of major intersections in order to ensure an efficient and safe traffic flow.
