Feasibility Study of Integrating WVDOT Linear Referencing System Center Line with Statewide Addresses and Routing Information

摘要

State DOTs use road centerlines to manage extensive transportation system data such as road physical conditions, traffic measurements, and highway projects. The WVDOT has recently completed a GIS base map project to create a linear referenced road centerline, and wants to develop a single, comprehensive, statewide road centerline dataset that can serve the entire DOT GIS needs. The objective of this project is to review technical issues regarding the feasibility of road network integration in West Virginia which incorporates linear referencing, addressing, and routing capabilities. This study reviews existing transportation models and identifies implementation issues as well as DOT needs. The study shows that the revised/improved UNETRANS data model can be successfully implemented accommodating WVDOT RIL system requirements. Using the advantage of Edit and Publish geodatabase design practices, the DOT can continuously develop and perfect the data model and migrate from the old system in stages. Creating and maintaining a statewide dataset that includes the attributes (e.g., one way roads, turn restrictions, etc.) required to support full automated routing (traversing) would be challenging and costly. The DOT should approach the routing requirement as a long-term project and develop an action plan.
