GIS Methodology to Map Routes from a Truck Permit Database Utilizing a Linear Reference System and Network Analysis

摘要

Trucking companies can obtain permits from state agencies allowing them to haul oversize andoverweight (OSOW) loads. Most permit systems assign a specific route to be followed thataccounts for various network travel restrictions. The routes assigned in these permits canprovide a wealth of information for different types of transportation analyses. Unfortunately, thepermit data is not always generated by a Geographic Information System (GIS) or archived in amanner that facilitates analysis in a GIS platform. This paper presents a methodology that wasdeveloped to process archived permit records from the West Virginia Department ofTransportation (WVDOT) so that they could be imported into GIS and plotted using the existingWVDOT Linear Referencing System (LRS). Some agencies do not have a GIS-based OSOWpermitting system, and those who use a GIS permitting systems are still faced with the challengeof integrating archive data with existing GIS/LRS platforms. The methodology presented in thispaper should be widely applicable for those facing such challenges. The automated procedurewas able to assign an LRS code and map 91.4% of the permits that contained route data for themonth of July 2011.
