Transit Operation Decision Support System (TODSS) Demonstration

Many transit agencies have installed fleet management systems (i.e., Automatic Vehicle Location (AVL) / Computer Aided Dispatch (CAD) Systems) to support real time operations. These systems generate large quantities of data and dispatchers often do not have enough time to digest the data for decision making in a normal operating environment and/or they are unable to recognize patterns of operational problems. Transit Operations Decision Support Systems (TODSS) are systems designed to support dispatchers and others in real-time operations management in response to incidents, special events, and other changing conditions in order to improve operating speeds, reduce passenger wait times, and restore service when disruptions occur. As part of a joint Federal Transit Administration (FTA) and Intelligent Transportation System (ITS) Joint Program Office (JPO) effort, the "Core Functional Requirements For Identification Of Service Disruptions And Provision Of Service Restoration Options" was completed in May 2003. However, no transit fleet management system in the U.S. currently incorporates the TODSS core functional requirements for either service disruption identification or provision of service restoration options. This project Implements and tests the viability of the core requirements in a prototype TODSS system. Project outcome: The prototype TODSS was accepted and became operational in March 2009. The core functional requirements were validated, and the system is producing many benefits including a drastic reduction in the number of data messages (e.g., service disruptions) to dispatchers and the provision of uniform service restoration responses by dispatchers within and among Pace's divisions.
