Abstract

Medina, the second Holy City for all Moslems, has recently experienced remarkable growth in all fields of activities. Major changes have resulted in its urban development pattern which influenced the shape of road network and traffic patterns and characteristics. Three comprehensive traffic Studies have been performed to evaluate and forecast traffic volumes in Al-Medina Al-Munawara. The first was by Robert Mathew and Johnson Co. in 1971. The second was by the Group of Arab Consultants for Development and Reconstruction in 1978 while the third was a review study by the World Bank in 1984. Although these studies have collected a valuable amount of data about road and traffic, each study has some deficiencies where traffic forecasts by all studies are not valid at the present time . Moreover, some links have been added to the road network like Manakhah tunnel and the two way bridge in the first ring road which makes quite urgent, the need for futher study and analysis in both the short and long terms. The paper reviews the previous studies, analyses the data, surveys the existing situation of the network and intersections, evaluates the traffic and road conditions and suggests appropriate steps towards developing two appropriate transportation planning strategies, short and long terms, to achieve improved traffic operation in the Holy City of AL MEDINA AL-UNAWARA.
