I we have to, then I would raise the bicycle lane (green boxes) where motorists would make the right turn, forcing the motorist to slow down. If the motor vehicles don't slow down, they get a jolt from the raised crossing, so they don't do that again.
Don't forget to provide input to the City. They can sometimes be convinced to improve bad design if they get enough public feedback. For example the Port Union bike lanes went from paint to physically separated after public feedback. Painted bike lanes aren't good enough on a street with a 50 km/h speed limit like Martin Grove.Bikes lanes aren't support to cross live traffic lanes like that, period. It's appalling we're still designing crap like this.
Keeping cyclists on the right is safer if the intersection is designed properly, ie. where turning drivers encounter cyclists at a right angle. Protected intersections are best. A forced merge at an intersection is always a bad idea and guaranteed to turn off people who are "interested but concerned" about cycling, which is the majority. Which of course defeats the purpose of this project.There is no perfect answer, if you keep the bikes in the right lane then vehicles turning right will cut them off. I actually prefer the way it's handled above, as long as there is lots of green paint, poles etc etc. In the rendering above I would keep painting a bit further east..
