Grey Models for Short-Term Queue Length Predictions for Adaptive Traffic Signal Control

no code implementations29 Dec 2019 Gurcan Comert, Zadid Khan, Mizanur Rahman, Mashrur Chowdhury

Thus, the objective of this study is to develop queue length prediction models for signalized intersections that can be leveraged by ASCS using four variations of Grey systems: (i) the first order single variable Grey model (GM(1, 1)); (ii) GM(1, 1) with Fourier error corrections; (iii) the Grey Verhulst model (GVM), and (iv) GVM with Fourier error corrections.
