Description

Hyperloop is a new mode of high-speed mass transportation not only able to reduce transit times but also afford passengers an on-demand experience. In contrast to traditional mass transportation systems that update fixed operating schedules year by year, the Virgin Hyperloop Mass Transportation System (VHOMTS) can dynamically redistribute vehicles in real time to minimize the passenger wait time even in the highest demand peaks and reduce its service expenditures in downtimes without impacting passenger experience. To do so efficiently, the VHOMTS uses prediction of passenger origin-destination demand in the next hours.

Patryk Oleniuk and Sandhya Raghava show the process for the creation of Virgin Hyperloop One’s passenger origin-destination demand prediction model for driving simulation and analysis of system performance under a wide range of operating conditions and real-time vehicle redistribution.

They explore historical data gathering, data transformations, and pattern analysis, as well as model selection and training using recent DNNs and compare it with other conventional methods. You’ll understand the architecture and methodology the company used to train on GBs of demand data, perform distributed training of thousands of models, sweep multiple model parameters in parallel, verify, and save them for future use. And you’ll cover selected topics from feature engineering, such as the impact of weather and surrounding events on the prediction accuracy.

To substantiate the impact of the demand prediction, they present a set of case studies for prospective Hyperloop markets. The advantages of a forecast-based versus purely reactive scheduling system are quantified in terms of passenger wait times and system use using simulated operations. Patryk and Sandhya’s methodology for passenger origin-destination demand modeling could also be applied to other modes of transportation, like cars, scooters, or cargo.
