Josh Auld, CTS Fellow, will present a seminar entitled "Activity Planning Processes in the ADAPTS Activity-Based Modeling Framework", Tuesday, November 17th
Download: "Activity Planning Processes in the ADAPTS Activity-Based Modeling Framework"
This presentation describes the representation of the activity planning process utilized in a new activity-based microsimulation model called the ADAPTS (Agent-based Dynamic Activity Planning and Travel Scheduling) model, which dynamically simulates activity and travel planning and scheduling. The model utilizes a dynamic activity planning framework within the larger overall microsimulation system, which is a computational process model that attempts to replicate the decisions which comprise time-dependent activity scheduling. The model presents a step forward in which the usual concepts of activity generation and activity scheduling are significantly enhanced by adding an additional component referred to as activity planning in which the various attributes which describe the activity are determined. The model framework, therefore, separates activity planning from activity generation and treats all three components, generation, planning and scheduling, as separate discrete but dynamic events within the overall microsimulation. The development of the planning order model, which determines when and in what order each activity planning decision is made is the specific focus of this paper. The models comprising the planning order framework are developed using recent survey data from a GPS-based prompted recall survey. The model development, estimation, validation, and its use within the overall ADAPTS system are discussed. A significant finding of the study is the verification of the transferability of the activity planning order model.
Josh is a PhD student in the department of Civil and Materials Engineering at the University of Illinois at Chicago (UIC). His primary research interest is in the field of travel demand modeling, specifically focusing on activity-based modeling approaches. His current research focuses on activity-based modeling using a behavioral process-based approach. This involves collecting and analyzing activity-scheduling and travel information to understand the underlying decision processes and integrating these processes into the full travel demand model. His advisors are Dr. Abolfazl (Kouros) Mohammadian (Civil and Materials Engineering) and Dr. Peter Nelson (Computer Science).
