The only solution to Bristol's congestion problems is a congestion charge with the main arterial roads into the city's central area made clearways.
It's a chicken and egg situation tho...
You can't start imposing a congestion charge unless there's both a viable and reliable public transport option in place to take those drivers off the road first
Was a completely different situation in London where it's been introduced... they have not just the tube and London Overground, but probably the most comprehensive bus service in the country. When I moved to London myself for a while, owning a car wasn't even a consideration as it made no sense vs the public transport options
Moving back to Bristol it soon became apparent that not just to commute every day for me but to get pretty much anywhere i'd need a car
