Upcoming GIS in Transportation Webcast
Crash Location Tool: Recording and analyzing crash information
Sharon Hawkins of the Arkansas State Highway and Transportation Department (AHTD) will discuss AHTD’s Crash Location Tool, which provides the Department with a convenient way for law enforcement across the state to enter log mile locations and roadway information when recording crash information. The simple methodology and easy to use Google Earth format makes AHTD’s crash location database more accurate and safety analysis more precise. AHTD is also using an Incident Analyst tool to locate crash event Hot Spots/Crash Densities, Repeat Incident locations and produce finished maps and graphs that provide a quick, complete visual aid of the tabular crash data.

GIS Winter Newsletter
Now Online
The Winter GIS in Transportation Newsletter is now available here. This newsletter features an article by Eric Leaming and Brett Juul of Oregon DOT (ODOT), and Robert Kirkman of HDR, Inc. They discuss how upgrading ODOT's Excel-based Work Zone Traffic Analysis (WZTA) tool to a GIS-focused, web-based tool has delivered long-term organizational benefits.
Also included is an editorial by Ryan Buck of the Washtenaw Area Transportation Study (WATS) on how cloud technologies are revolutionizing the data creation and sharing process.

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.

Report on Applications of GIS to Highway Noise Analysis
Now available online
FHWA sponsored a research study to investigate current uses of GIS to support highway noise analysis. The final report from the study is now available here. A text-only version is also available here.
The report presents eight case studies that illustrate how select state Departments of Transportation are using GIS and geospatial tools for highway noise analysis. Major findings compiled from case studies are expected to support GIS and noise practitioners identify examples of noteworthy practices, consider the pros and cons of GIS applications for noise, and determine how these applications might be best utilized.
