Riverside Traffic Lights Totally out of sync.

The sequence is wrong so traffic going around the roundabout is clogging it up before it can exit. Its simple logic that if you let too many cars onto the roundabout before they can clear it smoothly, then it becomes a self jamming system even with moderate traffic. You need to look at the timing sequence urgently as its crap at the moment.
