Plans for the inner ring of the congestion charging zone are to be firmed up by the Greater Manchester Passenger Transport Authority (GMPTA) and the Association of Greater Manchester Authorities (AGMA) once local opinions regarding the placement of the boundaries have been sought.
AGMA deputy director Sir Richard Leese said: "Since proposals were initially announced, there have been detailed discussions with the highways authorities to make sure that natural community ties such as shopping areas and school catchment areas are not broken."
"We want to hear the view of communities, on where the inner ring boundary will sit, during our summer consultation."
Initial discussions will involve the placement of the Northern, Southern and South-eastern sections of the boundary.
Currently, the plans will see drivers charged during peak travelling hours depending on whether they are travelling from or into the zone. They will also be charged each time they cross the boundary in a 24-hour period.
Leese added: "We expect that only 20% of peak time drivers will actually pay any charge at all as they will not cross a ring in the direction of congestion. In fact we anticipate that only 1% of all daily drivers will pay the full £5 charge, with the average cost being less than £3 at current prices."
However, businesses affected by the congestion charging zone are appealing to have the charge capped in cases where drivers need to routinely cross the borders several times a day.
If the current plans are implemented, drivers will be charged £2 between 7am and 9.30am for entering the outer charging ring, which lies along the M60 ring road, and £1 for entering the inner charging ring.
They will also be charged £1 for crossing either ring heading away from the city centre between 4pm and 6.30pm.
