There has been some complaining in the letters page of the Argus: the closure of the Old Shoreham Road to build cycle lanes has apparently increased journey times for some of those who like to commute the mile or two from Hove to Brighton by car. But it hasnt brought the city to a halt, and I think it shows us we don't really need these "arteries" for cars as much as we think we do.
I happen to live in the area affected near the railway bridge. Normally our street is a hectic 'rat run' for cars associated with the Old Shoreham Road traffic. Now, it's blissfully quiet.
My friends who drive cars tell me its a pain having to use alternative routes, such as the A27 bypass, to get from Hove to Brighton. But it's not really that much of a pain, a few minutes extra.
If we closed the Old Shoreham Road to car traffic, then the buses would run superfast into Brighton. And my friends might think of taking a bus to get to the other side of town. Or even, heaven forbid, a bike.
This is the kind of city planning used by the Dutch. Design the residential areas in 'cells' using one way systems to control traffic. To get between 'cells' by walking or cycling or bus, use the most direct route. But if you want to go by car, you have to use a longer, fast flowing bypass: you can't "rat run" through the residential streets (injuring people along the way). 37% of journeys in Holland are by cycle, only 2% in the UK. We need to change the way we design our cities.
I thought it needed an integrated city plan to work properly. We need the rapid buses AND we need to rearrange traffic priorities AND we cycling and walking routes... or maybe the way is to do it quietly, one street at a time...
