Scottish roads too safe :: EclectEcon

White lines will be removed, or, rather, not repainted.

Read about the natural experiment that supports this policy in this story in the Scotsman:
Although white centre lines can greatly assist drivers on major unlit rural roads, research in Wiltshire has shown that when white centre lines on lit roads within a 30mph speed limit were not replaced, traffic speeds and accidents were both reduced. It is, therefore, proposed that a similar experimental policy should be adopted in Aberdeenshire when roads with street lighting within 30mph speed limits are resurfaced or surface dressed.
Thanks to EclectEcon for the link. Read his analysis here.
