GIS Based Road Network Analysis: In the Case of Gondar City, North Gondar, Ethiopia
Abstract
Road network has been view as a major dynamic force in influencing quality of life and shaping cities all over the globe. Network analysis is an operation in GIS, which analyses the datasets of geographic network or real world network. Network analysis examines the properties of natural and manmade network in order to understand the behavior of flows within and around such networks and location analysis. The major problems of road network are poor road quality, a lack of pedestrian walkways, a low accessibility level, and narrowness. Lack of segregated bikeways, insufficient street parking, excessive use of off-street parking, poorly built road intersections, inadequate terminals for passenger and freight transit, difficult bus and taxiways, and a lack of adequate road network relative to the size of the city. Then to solve this problems this project to develop the main of objective of analyzes the road network in the study area. This project used primary and secondary sources of data, the primary data GPS point’s field observation and the secondary data received road network data from Gondar city municipality office. Based on these data the projectors develop different road connectivity models including the shortest route selection model to selection of closest facility service area. In addition to this the results show that the highest road network connectivity and accessibility area of the study Marakie subcity is the first ranked and the lowest ranked sub-city is Jantekel due to connectivity measurement parameters.
