JOHNSON CITY, TENNESSEE INTELLIGENT TRANSPORTATION SYSTEMS (ITS) PROJECTS

In 1995, the City of Johnson City via the Johnson City MPO began implementation of a series of Intelligent Transportation Systems (ITS) projects with the sponsorship of the U.S. DOT and Tennessee DOT. This effort involves development of several transportation management systems elements with ITS capabilities in the State Route 381 (State of Franklin Road Med-Tech) and Interstate 26 Corridors. The projects involve multiple phases, described as follows:


Traffic Signal Improvements Map	Cable Channel 17 - Johnson City Traffic Information Daily

Phase I (1995-1997)

Conducted an operational test of an automated parking management system on the campus of the Mountain Home Veterans Administration Center.Instrumentation of automated parking detection systems on at the VA for three lots, using fiber optic, video, and ultrasonic sensors with information displayed on variable message signs.

Preparation of baseline studies for Med-Tech Corridor mobility factors, parking cost/benefit analysis, and user preferences.

Development of on-line, real-time interfaces between GIS mapping and data display and analysis and the parking management system.

Design of new city-wide traffic signal system with new controllers, software and signal equipment with pedestrian access and emergency management features.

Phase II (1998-2004):

Development of automated traveler information systems (ATIS) capabilities, including public access television, traffic monitoring, web-based information services and planning for a regional incident management system.

Upgrading and linkage of the City’s traffic signal monitoring system (Siemens-ACTRA) to GIS and other ITS elements.

Construction of new traffic signal network at 37 major intersections including mast arms and new controllers. Construction of Phase I of fiber optics network. Installation of video cameras at SR 381/US 11E Intersection for signal timing and actuation.

Design of Phases II and III of fiber optics backbone network to interconnect signal systems along major corridors in Johnson City as well as form the backbone for video, traffic sensor devices, and other ITS/incident management features to be installed in later phases of ITS project. The North State of Franklin Road traffic management system with signal upgrades and fiber connections will be under construction in 2004.

Phases III and IV

Will explore continuing development of these capabilities, plus additional elements including Incident Management along the I-26 corridor. As reported by the Johnson City Press, numerous tractor-trailer accidents have closed Interstate 26 for extended time intervals, and needs for an incident management system for the Johnson City area have become more acute since I-181 became part of the Interstate 26 system in 2003. Incident management planning is being coordinated via a Project Impact grant from FEMA. Discussions are underway to create a system of permanent message signs for placement on the I-26 Corridor between Asheville and Johnson City. A fiber optic network connecting the Traffic Management and Emergency Management Centers with E-911, the Transit Operations Center, and Public Safety and Public Works Departments located in City Hall is planned for 2004. Institutional collaboration and interagency agreements will be needed to facilitate the Incident Management System. The TCRP report, "A New Vision of Mobility" is an outstanding reference guide for new interagency partnerships.
