Develop a GIS-based Megaregion Transportation Planning Model

Few studies have focused on the development and implementation of megaregional transportation models. It is a big challenge to build such kind of models because they need to ensure theoretical soundness and methodological validity in academic and professional studies while at the same time to meet the expectation of public agency on the models for reliability, efficiency, and user friendliness. This study intends to fill the gaps to develop a geographic information system (GIS)-based operational model for megaregion transportation planning. It extends the spatial scale of a regional transportation model to megaregion, which accommodates larger areas, more passenger and freight trips, and more complex transportation networks. It aims to balance the priorities in both academic research setting and operational planning setting. It selects Texas Triangle, including Austin, Dallas, Houston, and San Antonio metropolitan areas, as an empirical case to demonstrate the procedure of analytical framework design, data inventory, model development, and model implementation. This study also estimates both personal access to employment opportunities and truck access to freight facilities in megaregion traffic analysis zone to facilitate transportation policy development in Texas Triangle.
