Arizona, United States
The Arizona 511 Model Deployment included a number of key enhancements to the previous statewide 511 system. The previous system became operational in March 2002 when Arizona Department of Transportation (ADOT) converted the ten digit telephone information system to 511. The enhanced 511 system became operational the following year (December 2003) and provided a number of enhancements including a redesigned telephone interface and voice recognition system, and new types of content including information on arterial streets, airports, weather, transit services, and local events. The Federal Highway Administration sponsored an evaluation of the Arizona 511 Model Deployment which included cost data collection and analysis.
The total capital cost of the Arizona enhanced 511 system was approximately $1,412,000 with annual operating costs for the first year at approximately $293,000. Annual operating costs for future years are estimated at $210,000. Federal funding for the model deployment totaled $1.14 million. Remaining funding came from ADOT and their 511 partners.
The table below and subsequent tables excerpted from the report provide additional cost component details.

With respect to recurring cost, the cost to operate the enhanced system in the first year was about twice as much to operate the pre-enhanced system. The increase in cost is attributed to program management support. This cost is expected to decrease in future years as less ADOT staff time and consultant support is required. The major cost drivers for the pre-enhanced system and the enhanced system are the phone charges and T-1 line rentals. The table below highlights operating cost expenditures and costs for future operations.
