My only advice would be to get off your bike and walk it across that intersection just like a pedestrian. For some odd reason, cars see you better if you are walking your bike than when you are riding it.
When I have particularly dangerous intersections to cross, I always opt to become a pedestrian for that situation. It's all about safety and survival.
Yes, do request that they change the light interval. Get a friend to make a little video of you walking across as a pedestrian, to show how short the light is.
Put it up on youtube and show it to the right people when you make your request.![]()
