Abstract
The objective of this paper is to document the development of an automatic procedure for routing of industrial freight vehicles such as oversized vehicle and hazardous material carrying vehicles on congested urban transport networks in Geographical Information System (GIS). The use of a network routing procedure within a GIS environment is one of the distinctive features of the proposed work. The study area selected for the present work is Greater Mumbai. As a first step of the work, complete GIS database is prepared in GIS-T software: TransCAD. Two modules namely oversized vehicle routing module and hazardous material carrying vehicle routing module were developed by using the script language (source code) of TransCAD. The objective of the first module is to develop an automatic procedure for routing a oversized vehicle by considering the width of road, type of road, vertical clearance restrictions under flyovers and adequacy of bridges as constraints. The objective of the second module is to find a path having less human exposure along the route. For this purpose two types of buffers are created for each and every link-one is a buffer of severe intensity and second one is of less intensity. The module will find the path having minimum human exposure along the severe buffer area. Finally, these modules are attached to the GIS map so that user can run these modules by selecting the origin and destination nodes with a click of a mouse button and gets the best path satisfying all requirements as output.
