Abstract (Summary)

The primary and most fundamental purpose of transportation planning is to support decision-makings for transportation systems with data and information. Models are extensively used in the transportation planning process in order to forecast future travel patterns and develop efficient future transportation systems. Travel demand modeling is at the heart of the transportation planning process. It is used to estimate the distribution of travel demand or traffic flows made on alternative transportation systems in the future. The last century witnessed the transition in the focus of the transportation planning process: from capitalintensive investment to policy domains and inventory-based planning that focus on operation and management. Throughout the years, travel demand modeling has been evolving to respond to the emerging planning contexts. Among all these evolutions, the most significant one is from the aggregate four-step method to the disaggregate and activity-based perspective.

This thesis is dedicated to the design and implementation of an activity-based modeling framework for Singapore, specifically focusing on the comprehensive development of the framework and moving the state-of-the-art into empirical and innovative implementations. (Abstract shortened by UMI.)
