Investigate An Appropriate Spatial Resolution For Large-Scaled Pedestrian Travel Demand Model, Qin Zhang, Kelly Clifton, Rolf Moeckel

Civil and Environmental Engineering Faculty Publications and Presentations

An appropriate spatial resolution plays a significant role in any travel demand models. It directly impacts the level of detail of model input data, outcomes, and sensitivities (Castiglione et al., 2014; Moeckel and Donnelly, 2015). Compared to motorized or bicycle travel, pedestrian trips occur over a shorter travel distance and they are sensitive to environmental conditions at a much finer grain. Thus, it is important for models to set an appropriate spatial resolution to capture variations in walking conditions, leading to better representation of pedestrian demand over space (Gehrke and Clifton, 2014).
