Moving Beyond the Automobile-Road Diets
What’s a road diet? Quite simply, traffic-calming expert Dan Burden responds , “A road diet is anytime you take any lane out of a road.”
The first time people hear about a road diet, their initial reaction likely goes something like this: “How can removing lanes improve my neighborhood and not cause traffic backups?” It seems counter-intuitive, but taking away lanes can actually help traffic flow smoother while improving safety for everyone.
Road diets are good for pedestrians: They reduce speeding and make vehicle movements more predictable while shortening crossing distances, usually through curb extensions or center median islands. They’re good for cyclists: Many road diets shift space from car lanes to create bike lanes. They’re good for drivers: Less speeding improves safety for motorists and passengers, and providing left-turn pockets allows through traffic to proceed without shifting lanes or waiting behind turning vehicles.
And here’s something to keep in mind during this era of lean budgets: Road diets are a highly-effective infrastructure improvement that can be implemented quickly and at low cost.
