Title: Entropy Maximizing Gravity Model of Passenger and Mobility Fleet Origin-Destination Patterns with Partially Observed Service Data
Accession Number: 01764110
Record Type: Component
Abstract: Mobility-as-a-Service systems become increasingly important in the context of smart cities, with challenges arising for public agencies to obtain data from private operators. Only limited mobility data were provided to city agencies, which are not enough to support the decision-making of agencies. This study proposed an entropy maximizing gravity model to predict origin-destination patterns of both passenger and mobility fleet with only partial operator data. An iterative balancing algorithm was proposed to efficiently reach the entropy-maximization state. With different trip length distributions data available, two calibration applications were discussed and validated with a small-scale numerical example. Tests were also conducted to verify the applicability of proposed model and algorithm to large-scale real data of Chicago TNC. Both shared-ride and single-ride trips were forecasted based on the calibrated model, and the prediction of single-ride has a higher level of accuracy.
