When I was in Singapore a few years ago I saw how their congestion charges worked. All the cars avoided the zone like the plague during the day. This caused severe traffic jams just outside the zone and then a huge 6:30 rush into the zone when the charging period ended. Traffic didn't move any faster, it just moved the problem somewhere else. Does you city have congestion charges? Do they work?
