Get rid of the bus lanes that serve little purpose, other than causing tailbacks to other vehicles as two lanes merge into one. Next, rephase traffic lights. A good exampl eof this is Graet ancoats Street: If you are at a red light, the ones a few yards up are on green. As you approach the next ones, they have just gone to red. Introduce the "Green Wave" as they used to have in London (until they wanted the con charge and altered it) If you drove at 30 mph , the lights would be in your favour the full distance.
