Develop long-term vision and goals for agency’s ITS program and ensure timely completion of long lead-time activities to support future ITS initiatives.
Chattanooga Area Regional Transportation Authority's experience in deploying transit ITS
- Develop and update agency’s ITS concept of operations plan annually to ensure having a current roadmap for agency’s ITS program. In 2004, CARTA prepared a System Overview Update report, which is akin to a Concept of Operations plan, to document a long-term vision of how agency wanted to use ITS. The report included the following key items:
- A Chattanooga Regional Transit ITS Overview Diagram that depicted the current and planned ITS technologies 
- Vision and goals
- Descriptions of deployed ITS technologies
- Descriptions of ongoing and planned procurements
- An implementation schedule
- Formulate and utilize agency’s long term vision for ITS program to take advantage of relevant funding opportunities. Having a documented long-term vision helped CARTA take advantage of short-term opportunities that arose. For example, CARTA was approached by the University of Tennessee (UT) at Chattanooga with funding to support the installation of arrival time signs at several bus stops on CARTA routes in the UT Chattanooga campus. At the time that this opportunity became available, CARTA did not have all of the systems in place to support real-time bus arrival time information. Realizing that real-time arrival time information was consistent with its long-term plans, CARTA re-organized its planned deployment activities to fast-track those items needed to support arrival time signs.
- Identify and understand agency’s goals for ITS program and sequence the long lead-time activities early enough for their timely completion to support the long-term goals. First, understanding the long-term goals helped CARTA ensure that all the necessary preliminary activities were completed to support the long-term goals. This was particularly important with regard to long lead-time items with a long lifetime, such as bus purchases. For example, in 2006 CARTA added requirements that bus purchases include multiplex systems to better support the agency's plans for automated vehicle monitoring (AVM). A bus with multiplex system allows the AVM to perform enhanced monitoring of more devices than a bus without a multiplex system can do. The AVM system on older CARTA buses monitors fewer devices than the system on those purchased after 2006.
