• Abstract:
  We extended existing algorithms for estimating latent traffic state from loop detector and connected vehicle to account for spill back effects. The traffic state estimates are input to adaptive traffic signal control algorithm which dynamically updates splits and offsets. Splits are determined based on the proportionally fair rule, and the offsets are set to maximize through-band while taking into consideration the shockwave effect. The algorithm is implemented for two signalized corridors (Fig 1) in PTV VISSIM and the output emission is measured and compared against the output of a regression-based model derived using output from EPA MOVES under the same input data.
