The economics of crowding in rail transit [PDF]

open access: yesJournal of Urban Economics, 2017
Abstract We model trip-timing decisions of rail transit users who trade off crowding costs and disutility from traveling early or late. With no fare or a uniform fare, ridership is too concentrated on timely trains. Marginal-cost-pricing calls for time-dependent fares that smooth train loads and generate more revenue than an optimal uniform fare. The

Short-term passenger flow forecast for urban rail transit based on multi-source data

open access: yesEURASIP Journal on Wireless Communications and Networking, 2021
Short-term passenger flow prediction in urban rail transit plays an important role because it in-forms decision-making on operation scheduling. However, passenger flow prediction is affected by many factors.
