Evaluating Alternative Operations Strategies to Improve Travel Time ...

SHRP 2 L11: Final Appendices
QuickZone Traffic Delay Estimation Tool (2001-ongoing)
The purpose of QuickZone is to develop estimates of work zone traffic delays. It also allows the
estimates of the cumulative impact of multiple concurrent work zones (including delays and
economic impacts on travelers and local businesses) under sequential flagging operations, partial
closures, long durations of full closures, and a series of periodic full closures with a signed detour.
QuickZone also supports construction cost and delay cost trade-off analyses.
511/Travel Information Services Assessment (2003-ongoing)
This is a methodology to quantify the mobility benefits of travel information services (including
511) using archived traffic sensor, travel advisory, and weather data. The methodology has been
applied to assess benefits of traveler information services in locales across the country. The most
recent study provided quantitative support for Utah DOT to enhance Salt Lake City’s 511 from an
advisory to a travel-time based service. Similar work has been initiated with the MTC in San
Francisco.
Urban Congestion Reporting (2002-ongoing)
The purpose of the Urban Congestion Reporting is to monitor and report monthly congestion in
20+ cities across the nation and characterize trends as well as contributing factors (weather,
accidents, special events, etc.). Measures were developed that describe the intensity, duration and
day-to-day variation in congestion, as well as a series of graphical one-page summaries for traffic
managers and decision makers.
ITS Deployment Site
The ITS Deployment Statistics Web Site (http://www.itsdeployment.its.dot.gov) is administered by the
Research and Innovative Technology Administration (RITA) who coordinates the U.S.
Department of Transportation's (DOT) research programs and is charged with advancing the
deployment of cross-cutting technologies to improve the Nation’s transportation system. As
directed by Congress in its founding legislation, RITA leads DOT in:
• Coordinating, facilitating and reviewing the Department’s research and development
programs and activities;
• Advancing innovative technologies, including intelligent transportation systems;
• Performing comprehensive transportation statistics research, analysis and reporting; and
• Providing education and training in transportation and transportation-related fields.
As part of the ITS Deployment site, RITA provides access to data that were gathered by the United
States Department of Transportation (USDOT) Intelligent Transportation Systems (ITS) Joint
Program Office (JPO) to measure the level of ITS deployment in 108 metropolitan areas (78 of the
Nation’s largest metropolitan areas plus 30 of the nation’s medium sized metropolitan areas) and
the 50 states. It generally includes survey data from 2004 through 2007 on various topics such as
the following:
• Arterial Management
o Characteristics of Signalized Intersections
o Roadside Technologies to distribute en-route traveler information
o Information Dissemination to the Public
• Freeway Management
o Freeway Surveillance
