    Abstract

    A major component of neighborhood design is the road network and their efficiency However, little attention has been given to neighborhood alleyways in assessing network efficiency. This study highlights the necessity of studying both streets and alleyways when assessing network connectivity efficiency. Taking Dubai as a case study, the research evaluates eleven neighborhoods with different streets and alleyways systems designed during different growth periods. The focus is placed on the efficiency of different street layouts and explores the contribution of alleys (sikkak in Arabic) to that efficiency. A Pedestrian Route Directness (PRD) test is used to assess the efficiency of each neighborhood street layout along two scenarios. In the first, alleys are not included as part of the street network; in the second one they are considered. Findings show that there is a decreasing trend in road efficiencies in Dubai neighborhoods and a decline in the presence of alleys. Additionally, alleys improved all road networks once added to the network showing an improvement in average PRD values, network densities, and plots passing the test.
