Allow drivers to turn left on red lights (similar to how traffic lights work in the US) or build left turn 'sliproads' like the one between Asda and Lichfield Rd.
Remove unnecessary sets of traffic lights like the one outside Stafford Leisure Centre as you can cross at the Esso garage set.
Get the filtering and timing on all traffic lights changed accordingly as some of them are shocking.
Change Beaconside into a dual carriageway, build your proposed new road between the Fire Station and Walton on the Hill that may help with the gridload that is Lichfield Rd and Weston Rd as traffic tries to head East via Radford Bank, continue it along your proposed route down to the M6 south junction roundabout.
Create a one way ring road around the Stafford town centre using Queensway, Newport Rd up until Station Rd along Tenterbanks/Chell Rd where it reconnects with Queenway, thereby using the existing road capacity in a flowing pattern, but some journeys may be made longer as a result that may promote walking/cycling.
The current proposed road through Doxey may help with the new planned housing.
