Rail Capacity Improvement Study for Heavy Rail Transit Operations

New technologies such as moving block Communications-Based Train Control (CBTC) may offer more cost-effective and timely solutions than traditional plant upgrades for certain scenarios. The objective of this study is to offer a combination of considerations and evaluation tools pertaining to relevant means of capacity improvements (technology, operations, route, and vehicle upgrades), conventional and emerging. Guidance regarding the economics is offered to help balance the mix to minimize cost of achieving the level of capacity improvements required. To meet this objective, the Transportation Technology Center, Inc., has evaluated various aspects of the present capacity limitations vs. ridership for two large rail transit systems in the United States to determine capacity constraints and to identify areas where improved capacity might be needed.
