Abstract

The study aims to analyse the road network in the central region of Abha City using geographical information systems (GIS) to identify the characteristics of the road network in terms of the degree of connectivity, circuitry, accessibility and density. Additionally, it analyses the relationship between the network lengths and population distribution. The study finds out variance in the length and number of roads at the level of residential neighbourhoods in the central region of Abha City. It further concludes that the intersection distribution of roads takes a south-eastern north-western direction and increased connectivity in the various districts of the central region of Abha. The connectivity of the majority of road networks increases by 60% while the circuitry in half of the central region of Abha is more than 50% with low efficiency of road connections leading to downtown.
Therefore, the study recommends that more road connections are to be built to create direct links between communities to raise the adequacy, efficiency, interconnectivity and integration of the network.
