The geographic information systems are applied in the transportation analysis of AlMada’an city about 30 km southeast of Baghdad city in Iraq. Cities suffer from traffic jams, especially during peak hours. These traffic jams increase in special circumstances such as blocking a certain road for maintenance, security reasons, or during religious events. The work required the establishment of the street layers of AlMada’an city and addressing all the problems and errors that accompany the work to reach the construction of an integrated transport network with all network details. Alternatives and hypotheses included the blocking of a particular road and searching for an alternative road that represents the easy path between two ends. Geomedia Transportation analysis software is used in this application to solve the problems and achieve the aims of the study. Many cases and trials were applied for different road segments in the network to check the application efficiency. The test reflects excellent results everywhere, so we suggest using the application to help local government to find alternatives before blocking any road to avoid crowds. Also, we suggest using the software when entering the street layers into a GIS where its techniques help builds a network.
