  • New mixed-methods papers on pedestrian interactions with bicycles and cars

    Two new open-access papers from the REACT Lab examine public perceptions of comfort and safety for pedestrians interacting with cars and bicycles in unsignalized crosswalks.

Welcome to REACT Lab at UBC

React Lab is a group of researchers dedicated to finding ways to make our transportation systems more effective, sustainable, equitable, and healthy. Our current research focuses on utilitarian bicycle and pedestrian travel analysis and modeling (speed and route choices, facility and network design, comfort and safety, energy expenditure, air pollution uptake, and more). We do this work on the unceded lands of the Coast Salish nations, with the guiding values of integrity, rigor, creativity, and empathy.
