Abstract
Traffic models demand large amounts of data some of which are: time to travel a given road length, which streets are restricted for which vehicles, the speeds along the given road and which street are one-way. GIS is a natural tool for handling most of these data as it can ease the work process and improve the quality control. The research used ArcInfo to carry out urban traffic network analysis of Abuja, the Federal Capital City of Nigeria. The methodology can be used on not only a simple street network analysis but it can support multi edge sources to model a complex multimodal networks. The research covers the following tasks: Choosing and developing the source workspace, identifying the sources and the role they will play in the network, modeling the connectivity, defining attributes and determining their values. In addition, it also highlighted the following analyses: finding the best route, finding the closest facility, finding the service area and creating the O-D cost matrix.
