|Issue Date: ||23-Aug-2007|
|Abstract: ||An urban road maintenance management system has been developed in this study. The seeks, among others, to address the non motorized transport peculiar need of the road network in Tamale,
A road condition survey was undertaken in 2004/2005 on the Tamale road network to collect primary data for the development of the system. Road definition, inventory, defect and NMT lane data were collected. The data was used to develop an MS Access 2003 desktop database and also update a digitized Tamale road network map in GIS environment. Visual basic.net programming language was used for the decision support tool development. Cost of treatment of different road defects were studied from the maintenance unit of the
Department of Urban Roads and the Department of Feeder Roads and questionnaires on agency
and road user perception of the destructive nature, cost of repair and effect on riding comfort of various defects were also administered to engineers in these agencies and road users. Coupled with work from literature, a customized pavement rating form was developed to calculate the pavement condition index (PCI) of road links.
The system recommends appropriate treatments in relation to the PCI of every link and ascertains its condition assessment. Based on the PCI category, the functional classification, economic factor and the traffic level of the road, the urgency of the treatment of one link over another was generated. Customized thematic ArcGIS maps were developed capable of displaying the different road classes, pavement types and the number of the different functional classes of roads within the Tamale network was established as 64, 149, 430 and 495 respectively for A, B, C and D roads. Maps on location of drains, culverts, traffic lights and other road inventories could be shown. Reports could also be saved, emailed and exported MS excel, PDF, CSV document, text document, graphic document, etc. for further analysis|
