Public agencies involved in the management of transportation facilities resist efforts to integrate the operation of transportation management systems if that integration is perceived to involve a loss of local control and autonomy. A peer-to-peer wide-area computer network between the involved Transportation Management Centers is proposed as a solution to this institutional problem. The proposed network does not require central data processing or storage. Any agency on the network can collect and synthesize real-time data for any purpose, and perform real-time regional transportation management functions using the same system capabilities as are needed for local functions. The network supports continuous exchange of second-by-second monitoring and control messages among TMCs. All integration of operations is achieved by implementation of joint operating plans developed cooperatively by the involved agencies. Any agency's system can act as the "master" when needed in implementing such coordinated plans. Such a system isplanned for implementation as part of the Silicon Valley Smart Corridor project in California.
