Investigate an Appropriate Spatial Resolution for Large-scaled Pedestrian Travel Demand Model

摘要

It might be impossible to define an optimal spatial resolution. Although a finer spatial resolution is beneficial for model accuracy and sensitivity, there may not be a singular solution that fits various types of policy studies. As a result, the appropriate spatial resolution highly depends on the research questions that the model aims to address, the run times that the model shall not exceed, and the availability of spatial data needed to implement. Therefore, the aim of this paper is to try to balance these considerations and understand the various tradeoffs involved by testing various spatial scales for MoPeD for the Portland region.
