As long as you accept that a free right turn, followed by a u-turn, followed by another free right turn, is faster than waiting for the light at the intersection.
on-topic: seems to me that the problem is more with the highway not being able to handle the volume of traffic. Sure, you can make it less attractive for people to use the parallel road but that does little more than shift the problem elsewhere. In addition, these measures often hinder the residents themselves and emergency services as well, and depending on the choice of measure, can even increase problems. When they put speed bumps at the intersections in our area, we started to see an increase in structural damages in houses, as buses and trucks late in the evening had no trouble getting over those at normal speed, and just transferred energy from the bump, into the ground, and out to the houses.
