요약	Transportation has been one of the defining challenges of our age. Transportation decision makers are facing difficult questions in making informed decisions. Activity-based travel demand models are becoming essential tools used in transportatio
요약	In this dissertation, we explore a framework that develops the state-of-the-art generative activity-based urban mobility models from raw cellular data, with the capability of inferring activity types for complementing activity-based travel deman
요약	To do so, we first present a method of extracting user stay locations from raw and noisy cellular data while not over-filtering short-term travel. Significant locations such as home and work places are inferred. Along this pre-processing pipelin
요약	With the processed yet unlabeled activity sequences, we improve the state-of-the-art generative activity-based urban mobility models step by step. First, we designed a method of collecting ground truth activities with the help from short range d
요약	We apply the models to the data collected by a major network carrier serving millions of users in the San Francisco Bay Area. Our activity-based urban mobility model is experimentally validated with three independent data sources: aggregated sta
요약	One direct application of the urban mobility model is travel demand forecasting. Predictive models of urban mobility can help alleviate traffic congestion problems in future cities. State-of-the-art in travel demand forecasting is mainly concern
