GIS Webcast: Vermont Agency of Transportation - Making Right-of-Way Accessible
A summary of the summer GIS in Transportation webcast is now available here. Nina Safavi and Ryan Cloutier of the Vermont Agency of Transportation (VTrans) discuss the development and application of VTransí Right-of-Way (ROW) Viewer, a web-based GIS application that allows users to view all of the agency's ROW data in one location.

Geospatial Data Collaboration: Tools for Data-Sharing
Recording now available
A recording of the Geospatial Data Collaboration: Tools for Data-Sharing webcast is now available here. During the webinar, FHWA highlighted how transportation agencies are developing GIS-based screening tools, data libraries, information portals, and other geospatially based tools that support improved data-sharing, coordination, and more effective decision-making. The presenters provided specific examples of noteworthy practices and initiatives from State Departments of Transportation (DOTs). Staff from these agencies answered questions about their noteworthy practices and initiatives during a Q&A panel at the end.

GIS Spring Webcast
A summary of the spring GIS in Transportation webcast is now available here. Laurie Goudy, Mike Sheffer, and Erin Lesh of the Maryland State Highway Administration (MDSHA) discuss the agencyís Enterprise Geographic Information System (eGIS), a geospatial data portal that allows internal agency staff to quickly and easily access an array of geospatial data and mapping applications for data-driven analysis and decision support.

GIS Spring Newsletter
The spring GIS in Transportation Newsletter is now available here. This newsletter features an article by Geno Koehler and Jim Conlon of Illinois DOT, who discuss the DOTís new over-dimension and overweight permitting system, called the Illinois Transportation Automated Permit (ITAP). In addition, Gary Baker of the U.S. DOT Volpe Center considers how the transportation field can realize the full potential of GIS technologies.

The Interoperability of Computer-Aided Design and Geographic Information Systems in Transportation
Report now available
As transportation agencies increasingly work toward streamlining their business processes, they face a variety of challenges in seeking to improve the interoperability of GIS and CAD. The Federal Highway Administration (FHWA) sponsored a research effort to explore the status of GIS and CAD integration and interoperability in the transportation field, and the report is now available here.
The report discusses how the following agencies use GIS and CAD together, how they use GIS-CAD interoperability to meet their needs, and the challenges, lessons learned, and benefits encountered by these agencies while implementing interoperable systems and striving toward full integration. The agencies include:
Kentucky Transportation Cabinet
Anne Arundel County, Maryland
Iowa Department of Transportation
Santa Clara Valley Transportation Authority
New Mexico Department of Transportation

Assessment of the GIS Needs and Obstacles in Traffic Safety
The Federal Highway Administration has recently released a report, available here, that explores the use of GIS for safety decision making at the state and local level, and considers opportunities for FHWA to use this technology to improve highway safety. The report found that while states are not generally using the full capabilities of modern GIS software to support advanced safety data analysis, most States are looking forward to enhancing their GIS and making use of advanced techniques in the future. States are aware of the MAP-21 requirements for statewide basemaps and a linear reference system that includes all public roadways, but cite administrative and technical barriers to success. The report includes recommendations for FWHA to help agencies overcome these challenges including tools, marketing and training, and research to fill gaps in knowledge.

Uses of Cloud Technologies for Geospatial Applications
Report now available
Great potential exists in using cloud technologies to support GIS applications, but their use is still evolving. To explore this in more depth, the Federal Highway Administration sponsored a research effort to investigate transportation agenciesí GIS and cloud computing initiatives. The report summarizing this research is now available here.
The report presents background information, a series of case studies, and a summary of conclusions based on the following initiatives:
Idaho Transportation Departmentís IPLAN
Maryland Department of Transportationís Miss Utility Tracking System, interactive mobile applications, iMap Application templates, and Enterprise GIS system
Ohio Department of Transportation and Mid-Ohio Regional Planning Commissionís Location Based Response System programs
Utah Department of Transportationís UPlan
Washtenaw Area Transportation Studyís (WATS) long-range transportation plan deficiency maps and Mi Community Remarks application, and interagency data sharing initiative

FHWA Geospatial Data Collaboration (GDC)
GDC is a new initiative for geospatial data-sharing sponsored by FHWA. The initiative encourages transportation agencies to use geospatial tools to share data, increase collaboration, and improve the quality and speed of transportation decision-making.
