Author’s Bio

I’m Rahul Raoniar, a fifth-year doctoral student, pursuing research in Transportation System Engineering (Department of Civil Engineering) at Indian Institute of Technology Guwahati. I love learning new things every day. Currently, I am working with Prof. Akhilesh Kumar Maurya on pedestrian risk-taking behaviour at intersection crosswalks. Prior to arriving at IIT Guwahati, I have earned a master’s degree in Transportation Engineering from Central Road Research Institute (CSIR-CRRI Lab, Delhi, India) and worked as a Trainee Scientist in CSIR-CRRI for consecutive 3 years; where I have studied the performance of Delhi’s transport systems.
