TRANSIT AGENCY LIGHT RAIL INCIDENT RESPONSE BEFORE AND AFTER ICM DEPLOYMENT: STRATEGIES AND CONSTRAINTS

摘要

As part of the U.S. Department of Transportation's ICM Initiative, Dallas Area Rapid Transit (DART) purchased new automatic passenger counter (APC) technology for their light rail system to provide passenger counts in real-time to their train control center and to provide data to the Integrated Corridor Management (ICM) decision support system. By gaining access to real-time passenger counts and location, DART hopes to respond more effectively to unplanned incidents on the rail network by enabling more responsive service adjustments such as bus bridging and additional consist deployment. This technology also allows DART to respond to mode shift recommendations that are part of the larger ICM project along the US-75 corridor. This paper summarizes how DART responded to rail incidents before the introduction of ICM, addresses what has changed after ICM deployment, and identifies constraints to optimum responses.
