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

GIS Fall Newsletter
The fall GIS in Transportation Newsletter is now available here. This newsletter features an article by Warren Kron, GISP, and Justin Priola, GISP, of the City of Baton Rouge and Parish of East Baton Rouge (City-Parish), LA. They describe the conversion of the City-Parish's GIS road network to a linear referencing system (LRS). In addition, Charles Fay of the Transportation Research Board, and Omar Smadi of the Iowa State University, highlight the importance of using GIS as a tool to integrate, analyze, and visualize data from the second Strategic Highway Research Program naturalistic driving study.

Upcoming GIS in Transportation Webcast
Iowa DOT: Snow Plow Tracking from Start to Finish
Please join the Federal Highway Administration (FHWA) for its 21st installment in a quarterly series of webcasts highlighting applications of geospatial technologies in transportation.
The webcast will take place on January 15th from 2-3 PM ET.
Eric Abrams, Geospatial Infrastructure and Coordination Manager, and John Hart, Senior Transportation Engineer of the Iowa Department of Transportation, will discuss the departmentís implementation of a snow plow tracking system capable of collecting locations, quantities and environmental conditions. The webcast will explore the initial project concept, how the concept evolved and was implemented, and lessons learned from the project. It will also address how Iowa's linear referencing system made tracking easier, and how truck hardware and leveraging web services helped with disseminating information. The webcast will include a live demonstration of the system.
To access the webcast, please see the information listed below:
The intended audiences for this webcast series are planners and GIS practitioners from State Departments of Transportation, Metropolitan Planning Organizations, FHWA Division Offices, and State and Federal resource agencies.
If you would like highlight one of your agency's geospatial applications in an upcoming webcast, please contact Paige Colton (firstname.lastname@example.org or 617-494-2361). Information on previous webcasts can be found here on FHWAís GIS in Transportation website.

GIS Fall Webcast
Summary now online
A summary of the fall GIS in Transportation webcast is now available here.
Bryan Semore of the Tennessee Department of Transportation (TDOT) discussed and demonstrated the DOTís new web-based roadway information management system. TDOT has a rich history of deploying technology to help manage critical infrastructure facilities. For example, TDOTís Tennessee Roadway Information Management System (TRIMS) provided tremendous benefit to TDOT by performing complex data maintenance as well as roadway analytics. However, the cost of deploying and maintaining this largescale client/server based application was a big challenge. To address these issues, TDOT decided to create E-TRIMS - a new web-based application with the same analysis capabilities in a modernized format. E-TRIMS provides a customizable map interface with "Road Finder" query capabilities, allowing output on the map or as a tabular report, as well as thematic maps and charts. In addition, E-TRIMS allows users to perform and save any number of queries and change map settings for future use or access by other DOT users.

Case Studies in GIS for Internet Portals
Now available online
FHWA sponsored a research effort that investigates the experiences of transportation agencies in the deployment of Internet-based mapping portals based on GIS. The report summarizing this research is now available here.
The report presents background information, a series of case studies, and a summary of conclusions given the experiences of the Kentucky Transportation Cabinet's Interactive Mapping Program; New York State DOT's Oversize/Overweight Pre-Screening Tool; Georgia DOT's GeoTRAQS; Iowa DOT's Snow Plow Portal; and Kansas DOT's KGATE system.
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.
