To examine the potency of using a real-time control method for reducing environmental impacts we developed a two phase methodology: (1) constructing a real-time PT tactic-based control (TBC) system using three tactics: holding, skip-stops, and boarding limit, (2) designing a LCA process to evaluate the environmental impacts of the PT system before and after the operational use of TBC.

The two phases are explicated as follows. Fig. 1 shows the methodology.
