Consistency of signal coordinate control models under different traffic conditions

Considering the different time that platoon reaches downstream intersection, this paper proposes corresponding stop and delay coordinated control models for under-saturated and over-saturated traffic conditions. With the cumulative arrival-departure diagrams, uniform stop and delay models for under-saturated and over-saturated traffic conditions are proved to be consistent and accurate by formula derivation. It provides a basis on deducing the stop and delay general formulae under signal coordinate control mode theoretically.
