A hybrid strategy for real-time traffic signal control of urban road networks [PDF]

, 2010
The recently developed traffic signal control strategy known as traffic-responsive urban control (TUC) requires availability of a fixed signal plan that is sufficiently efficient under undersaturated traffic conditions. To drop this requirement, the well-
