Highlights A reinforcement learning-based agent model is developed for travel demand forecasting. The method is capable of learning and imitating people travel behavior from unlabeled GPS data. A synthetic dataset is generated and evaluated by comparing with real mobility dataset.

    Abstract Understanding individual and crowd dynamics in urban environments is critical for numerous applications, such as urban planning, traffic forecasting, and location-based services. However, researchers have developed travel demand models to accomplish this task with survey data that are expensive and acquired at low frequencies. In contrast, emerging data collection methods have enabled researchers to leverage machine learning techniques with a tremendous amount of mobility data for analyzing and forecasting people’s behaviors. In this study, we developed a reinforcement learning-based approach for modeling and simulation of people mass movement using the global positioning system (GPS) data. Unlike traditional travel demand modeling approaches, our method focuses on the problem of inferring the spatio-temporal preferences of individuals from the observed trajectories, and is based on inverse reinforcement learning (IRL) techniques. We applied the model to the data collected from a smartphone application and attempted to replicate a large amount of the population’s daily movement by incorporating with agent-based multi-modal traffic simulation technologies. The simulation results indicate that agents can successfully learn and generate human-like travel activities. Furthermore, the proposed model performance significantly outperforms the existing methods in synthetic urban dynamics.
