Chattanooga, Tennessee is a city of about 170,000 people (about 500,000 in the metropolitan area) located near the Tennessee-Georgia border. The Chattanooga Area Regional Transportation Authority's (CARTA) provides transit services for the City of Chattanooga and portions of nearby counties. CARTA serves this area by providing fixed-route bus service (16 routes), curb-to-curb transit for people with disabilities (Care-A-Van), a free electric shuttle in the downtown area, an incline railway up historic Lookout Mountain, several parking garages, and management for much of the on-street parking in the downtown area. It is a moderate-sized transit organization in a moderate-sized community. In 2003, CARTA undertook an ITS project, SmartBus, which entailed introduction of many interdependent technologies across the entire range of CARTA operations:
- Various network technologies were deployed to provide connectivity across CARTA's fixed and mobile assets
- Technologies were deployed to help automate and modernize many field operations, such as automatic passenger counters and new bus fare boxes
- Technologies were deployed to help automate and modernize many back office operations, such as new dispatch and revenue management systems
- A data warehouse was developed to consolidate data collected during CARTA operations, and reporting tools were created to take advantage of this data warehouse
The deployment was challenging and susceptible to risks of failure. Effectively managing the risks, CARTA successfully implemented the SmartBus technologies over a period of 6 years, from 2003 to 2009, with most of the deployment completed. In November 2009, the Intelligent Transportation Systems Joint Program Office (ITS JPO) of the United States Department of Transportation (U.S. DOT) published an independent evaluation report documenting CARTA’s experiences in planning and implementing the SmartBus project. Presented below are lessons learned from CARTA’s experience that could be beneficial to other mid-size transit agencies’ planning for implementation of ITS program.
