Leffler, David (author), Burghout, Wilco (author), Jenelius, Erik (author), Cats, O. (author)The paper develops a simulation model and evaluates fixed versus on-demand operational designs of a station-based automated feeder service. The evaluation considers the operational cost and average passenger level-of-service trade-offs as well as distributional differences in waiting times. Two case studies are used to evaluate such trade...journal article 2021

Sampimon, Max (author)This project revolves around redesigning Demand Responsive Transport services for non-digital users. The Ombudsman has identified that in the past couple of years public transport (PT) operators are replacing fixed transit lines (FLT) by Demand Responsive Transport (DRT) services in low demand areas (OV-loket, 2017). DRT is more efficient,...master thesis 2020

Jorna, Nienke (author)Renewable energy sources like wind and solar, are intermittent, which means demand will not always match supply causing volatile and sometimes even negative electricity prices. For power companies it will be valuable to invest in technologies that can respond to those prices, which will result in an increasing flexibility of demand. However, to...master thesis 2020
