Customization of a Mobile Field Data Collection Application and Linear Referencing System to Support Geospatial Data Collaboration

Under a previous research project, Project # SPR-2253, “Development of the Digital Design Environment (DDE) ProjectWise™ – Phase 2,” the Connecticut Department of Transportation (CTDOT) initiated and accomplished significant work towards customization of a web-based editing application to facilitate field data collection of geospatial data assets, specifically road network characteristics. This application was known as the Mobile Asset Verification and Roadway Inventory Collection tool, otherwise known as “MAVRIC”. Field data collection of roadway geometry and asset information, and more specifically, simultaneous multi-asset editing/collection (otherwise known as “parallel data collection”), is a critical component of timely management of the geospatially accurate road network and associated attribution (e.g., lanes, shoulders, curbs, intersections, intersection approaches, etc.). This foundational data of the road network is the backbone upon which the CTDOT’s GIS is built, and a requirement under 23 CFR 924.17 for the Model Inventory Roadway Elements (MIRE) and All Roads Network of Linear Data (ARNOLD). The initial project targeted field data collection utilization and was successful in meeting the project goals. This next phase of the project looks to build upon the lessons learned during the first phase, incorporate additional customization to meet the needs to expanding CTDOT stakeholders, take advantage of additional technological advances CTDOT has made since the completion of the first project, and utilize the customized solution to help CTDOT personnel to enhance the overall quality and completeness of its critical roadway datasets, while providing metrics on time and resource savings that can be expected through implementation of a similar system. For the different types of data collection, a fully configurable customized application is needed.
