One of the local tv stations here did a great story on traffic light phasing. They first had viewers email them their worst bottlenecks and where they felt traffic lights hampered their commutes. After several weeks of collecting angry emails, they narrowed it down to a handful of intersections. Then they interviewed a local DOT person, and then brought them out to the worst intersection the viewers identified. The reporter said they spent about 30 minutes working on the lights and signaling. The reporter did say that traffic was flowing better and there were less cars backed up at the light after the DOT person corrected some of the signaling issues. Of course they ended the story by lamenting about how many traffic lights there are in the city and clearly the DOT have an uphill battle in keeping every intersection flowing well, but said they spend a lot of time at least trying to monitor the bad intersections.
