GEOGRAPHIC INFORMATION SYSTEM (GIS) BASED HIGHWAY ASSET MANAGEMENT SYSTEM FOR MOTORWAYS: CASE STUDY OF MAJOR PAKISTAN’S MOTORWAYS

Abstract

Result of pavement condition survey, conducted by NHA in 2005, showed that 43% of existing NHA network has remaining service life (RSL) of0 to1 year. Asset replacement value of National Highway was estimated more than 600 Billion in 2005 by Road Way Asset Management Division. This largest investment is deteriorating at fast pace, main cause being increased axle loading and lack of maintenance.The study was carried out to develop GIS based Highway Asset Management System(GHAMS) for M-1 and M-3Motorways.Digitized database was established to develop Query Basedinterface on ArcGIS. The developed system, GHAMS, produced different outputs like thematic maps, graphs and charts that would assist authorities and decision makers to carry out maintenance/rehabilitation works of NationalMotorways timely and efficiently. Moreover, this query based system would lead to save intense pavement damages and subsequent high maintenance / construction cost.
