Walking into me on a busy underpass

Description

I was walking in an underpass with no footpath and a man walks towards me in the opposite direction. I assume he has seen me and will make way for me, since I was closer to the wall of the underpass. Instead, he walks right into me in a way that can't possibly be accidental unless he was sight-impaired, and then keeps walking without a word of acknowledgment. I kept walking, and two seconds later I turned back and screamed at him "What the fuck do you think you're doing?" He never turned back, he kept walking, and I walked on since it was dark and I didn't know what else I could do about it and didn't want to pick a fight while no one else was watching.
