This research aimed to develop a quantitative-based model for determining the delay of pedestrian timing accommodation (PTA) into coordinated signals compared with the nonaccommodation (PTN) alternative. The idea for the research came from the need for a tool sought by practicing traffic signal engineers by which empirical judgments have chosen pedestrian accommodation. Practitioners can ascertain the best option (PTA or PTN) for a series of coordinated signals using the proposed model. The model was implemented into an open-source software available for general use. The proposed delay model was validated and its accuracy demonstrated using simulation. The model and related software will make it an easier and more systematic process for practitioners to choose between PTA and PTN at coordinated signals.
