Where Willingdon meets Hwy 1 takes the cake for me. I believe it is statistically one of, if not the worst, for accidents.
Coming from North Van and trying to get to Canada Way to pull into the electrcian building parking at BCIT was a fine art. For BCIT students at that end of the campus, we had/have to go across three lanes and squeeze into a left turn-only lane, which was always backed up 100+ feet before the off ramp in the morning.
So you have:
-Massive amounts of traffic pouring off Hwy 1 impatiently wanting to get past you, frequently squeezing around you illegally on both sides if you slowed down at all
-Approximately 100 feet to make four lane changes on a very busy road, that is going downhill after the highway overpass (poor visibility and high traffic speed)
-A huge line up of cars that don't want to let you in, since letting you in may mean sitting there for another long light (usually 2-3 lights minimum wait).
You have to be super alert and ready to pounce at any small opening or else you just piss everyone off. People were actually pretty good at letting me in, but I found the trick was to be very assertive and stick my hand out the window to hand-signal as well as regular signalling. Then of course a thank you wave after I force my way in.
Most people just futilly sat in the left most regular lane getting honked at and fingered for minutes until some kind soul took pity on them.
My dad used to work for Electronic Arts in the old building on the corner there and said he'd see at least one accident per day from his desk.
