An increasing number of 511 systems share boundaries and / or have significant travel in between them. This is also true along major travel corridors throughout the country. Callers in one metropolitan area may wish to dial 511 to find information not just for their local travels, but for their entire trip, which might include traveling through other metropolitan areas or regions and crossing state borders. This Deployment Assistance Report (DAR) is an outgrowth of the System Considerations section of the Consistency Guidelines. The purpose of this DAR is to offer 511 implementers technical advice on how to deal with callers who logically want information on transportation facilities and services outside of the area served by the 511 system. With the overlap and varied boundaries of agencies regions, travel patterns and the unknowns of cellular routing, 511 deployers need to look beyond their borders to make 511 a success with the traveling public. If 511 developers, deployers and operators accomplish regional interoperability through data sharing, then we may achieve national interoperability ultimately as well. This national interoperability may ultimately yield a 511 system where the caller may be asked, "City and state, please." Whether considering a call transfer or a data transfer option, the current expectation is not for full national availability of information via a local 511 service rather for full information availability within a region plus relevant travel corridors to and from the region. For those implementing systems, this DAR is intended to provide you with the best information available on options for call transfers and data sharing. These are the primary means available today to provide information from outside your region to callers
