Dr. Rahul Raoniar
Roads kill. I research why - and how to change that.
For over a decade, I've studied the small decisions - a glance, a hesitation, a missed signal - that separate a safe crossing from a fatal one. My research spans pedestrian behaviour, child safety, driver psychology, and crash risk across India and the United States.
I believe the best science doesn't stay on the page - it changes how we build streets and protect the people who use them.
