My approach is to learn the road traffic patterns. I have one of these type of roads on my commute.

At main intersections, and/or when approaching an intersection where it is common for several cars to turn right at each light cycle, then I take the lane. When not approaching one of those intersections, but instead just a slew of small intersections with occasional turners, I share the lane, but I'm in full-vigilance mode, easy on the speed, ready to break.
