Stability and Comfort in Mobile Robot-Pedestrian Interactions
Alireza Jafari, Hong-Son Nguyen, Yen-Chen Liu
Mobile robots in public spaces must ensure pedestrians' comfort, and yet empirical studies of walkers' subjective safety are rare. Many classical navigation algorithms do not disti…
Empirical Pedestrian Safety Assessment in a Mobile Robot Using a Predictive Social Force Model
Alireza Jafari, Yun-Hao Tsai, Yen-Chen Liu
Mobile robots are going to share the sidewalks with pedestrians. They must ensure their objective safety and respect the walkers' subjective safety/comfort. Computationally efficie…
Empirical Prediction of Pedestrian Comfort in Mobile Robot Pedestrian Encounters
Alireza Jafari, Hong-Son Nguyen, Yen-Chen Liu
Mobile robots joining public spaces like sidewalks must care for pedestrian comfort. Many studies consider pedestrians' objective safety, for example, by developing collision avoid…
Perceived Time To Collision as Public Space Users' Discomfort Metric
Alireza Jafari, Yen-Chen Liu
Micro-mobility transport vehicles such as e-scooters are joining current sidewalk users and affect the safety and comfort of pedestrians as primary sidewalk users. The lack of agre…
Dynamic Modeling and Stability Analysis of Balancing in Riderless Electric Scooters
Yun-Hao Lin, Alireza Jafari, Yen-Chen Liu
Today, electric scooter is a trendy personal mobility vehicle. The rising demand and opportunities attract ride-share services. A common problem of such services is abandoned e-sco…
