Duives, D.C. (author), Ton, Danique (author)Crowding is often analyzed using crowd dynamics variables. Yet, it is questionable whether quantitative variables fully describe the perception of crowdedness. This paper presents four case studies into the Pedestrian Level-of-Service (PLoS), featuring a 1) mass event, 2) shopping environment, 3) festival, and 4) touristic hotspot. The...journal article 2024

Alizadehsaravi, L. (author), Moore, J.K. (author)Bicycles are more difficult to control at low speeds due to the vehicle’s unstable low-speed dynamics. This issue might be exacerbated by factors such as aging, disturbances, and multi-tasking. To address this issue, we developed a prototype ‘balance assist system’ with Royal Dutch Gazelle and Bosch eBike Systems at Delft University of...journal article 2023

Das, Subasish (author), Tawhidur Rahman, Md (author), Kabir, Nuzhat (author), Oviedo-Trespalacios, O. (author), Dey, Kakan (author), Mahmud Hossain, Md (author)Children are one of the most vulnerable population groups in traffic crashes. Child safety seats (CSSs) can reduce the severity of crash outcomes for children. The use of CSSs has significantly increased in the U.S. over the last 40 years, but the use of CSSs in popular ridesharing services (RSSs), such as Uber and Lyft, is not widespread. This...journal article 2023
