تقييم و تحسين الأداء المروري لمعظم التقاطعات الرئيسة في مدينة غزة باستخدام برنامج سيدرا

Abstract EN

Gaza City suffers from traffic congestion in many places, which is concentrated at major intersections.

One of the reasons of the problem is that the selection of traffic control and geometric design at intersections are not scientifically based.

The design is not based on any traffic software, but it is based on trial and error.

Therefore, the objective of the study is to analyze the traffic performance of the major intersections (35 intersections) in Gaza City and to study various alternatives to improve traffic performance.

The methodology is based on collecting information from documented sources; where field survey was carried out including geometric and traffic data.

This was followed by an analysis of current traffic situation and studyingthe alternatives using SIDRA program.

The results of the analysis of traffic data at these intersections and through representation of these data on the spatial map using GIS technology showed that the most densely populated area is located in the middle of the city and that Omar Elmukhtar- Eljalaa intersection has the highest volume of traffic.

The results also showed that Elrasheed-Elthalith intersection has the lowest traffic volume.

The results of the analysis of the various traffic control alternatives at the intersections showed that the current traffic control at about 60% of the intersections (21 intersections) is not the best control.

The results revealed that the control at 11 intersections should be priority control; at 14 intersections should be roundabout; and at 10 intersections should be traffic signal.

Some of the recommendations that came out of this study are that there is a need for the concerned authorities to apply the outputs of this study and to repeat this study for other cities in the Gaza Strip.
