Article Citation - WoS: 2Citation - Scopus: 2Slow Motion in Corona Times: Modeling Cyclists' Spatial Choice Behavior Using Real-Time Probe Data(Univ Minnesota, Center Transportation Studies, 2024-11-11) Kourtit, Karima; Osth, John; Nijkamp, Peter; Turk, UmutThe recent COVID-19 pandemic has provided a renewed impetus for empirical research on slow and active modes of transportation, specifically bicycling and walking. Changes in modal choice appear to be sensitive to the actual quality of the environment, the attractive land use and built environment conditions, and the ultimate destination choice. This study examines and models the influence of cyclists' health concerns during the pandemic on their spatial destination and route choices. Using a large real-time dataset on the individual daily mobility of cyclists in the province of Utrecht, the Netherlands, collected through GPS-linked sensors on bikes (VGI, or volunteered geographical information), the analysis employs spatial regression models, Shapley decomposition techniques, and spatial autocorrelation methods to unveil the backgrounds of changes in spatial behavior. The results reveal that the perceived wellbeing benefits of bicycling in green areas during the pandemic have significantly influenced cyclists' choice behavior, in particular route and destination choice.Article Citation - Scopus: 1Flexible and Ecofriendly Keypad Based on Paper and Pencil(IEEE-Inst Electrical Electronics Engineers Inc, 2023-11) Er, Sahane Firdevs; Kalabey, Nurefsan; Hah, DooyoungPencil-on-paper electronics has gained growing interests as cost-effective, ecofriendly, flexible, and light-weight devices for various applications. In this letter, a flexible keypad employing pencil-on-paper capacitive touch sensors is presented. Spiral-type interdigitated sensors are interconnected via steel threads as well as graphite paths to constitute a ten-button keypad. Passivation of the sensors by means of acrylic paint coating works as protection against deterioration from bending, folding, and extended usage. Backing of the keypad with silicone provides extra durability. Sensor reading is administered by Arduino boards. The same manufacturing method is used to scale up the system to a 44-button keyboard. Functionalities of both systems are successfully demonstrated, and effectiveness of the passivation is verified.
