ABSTRACT
This paper presents a study on quantifying the exact impact of state estimation error on adaptive traffic signal control. The exact impact of state estimation error can be derived using the vertical queuing model and dynamic programming. The vertical queuing model, albeit a simplistic assumption, can be defined unambiguously, and when used to describe the system dynamics in the dynamic programming formulation, enables an exact global optimum to be computed. We further present a model to estimate the impact of state estimation error on multiple cycles of traffic signal operation, which will then be validated by the results obtained from the dynamic programming process based on the vertical queuing model.
