    • Abstract:
      The first 511 service became operational in the Cincinnati/Northern Kentucky area in July 2001. Less than two years later, over a dozen services are operational across the country serving more than 40 million people who, in total, are currently calling 511 nearly 1 million times a month. Every service in operation provides some form of information associated with roadway conditions. With many of the services likely to have their preponderance of callers interested in roadway conditions, the quality of roadway-related content will in many cases dictate overall satisfaction with 511. The 511 roadway quality ?levels? discussed in this deployment assistance report (DAR) are for the basic 511 telephone travel information service. Roadway data quality needs vary greatly by application: traffic incident detection, long-range system-wide planning / modeling, oversize truck permit routing, construction project report analysis, long-range impacts of suburban development, etc. It is understood that all of these activities may need different levels of data disaggregation and quality. The purpose of this DAR is to provide, in a single document, the most up-to-date information on guidelines, state-of-the-practice, state-of-the-art, implementation experience and lessons learned related to gathering and providing quality roadway content over 511 services. The main audience for this DAR is the planners and implementers of 511 systems. 33p.
