[Carfreeliving] Residential Driveways restrictions

[Dave Snyder]

All good points. When I saw it in Berlin, it *seemed to* work, with 
very few if not zero driveways, and plenty of space so that 
passengers could open their doors without banging cyclists, and 
adherence to the parking lane without having to put up barriers. That 
might not work here.



>Dave, even if there are 0 driveways (not sure how we'd achieve that 
>in a city that is nearly 100% built out) putting a bike lane/path 
>between parked cars and the sidewalk is a questionable idea at best. 
> Every intersection, you have cyclists popping out from behind a row 
>of parked cars, reducing their visibility and creating even greater 
>conflicts with turning vehicles and vehicles crossing 
>perpendicularly at the intersections.  Also, trash accumulates more 
>easily in that space and is more difficult to clear, especially 
>since you'd have to put up a barrier along the left of the lane to 
>keep parked cars out.  If a passenger opens their door, where does 
>the cyclist veer to avoid that if there is a raised sidewalk or 
>street furniture/trees to their right?  Pedestrians will spill into 
>the space, along the midblock sections as they stroll along and at 
>the intersections while they stand in the street/on the path waiting 
>to cross.  Making left turns legally and predictably is more 
>difficult.  Cyclists who use the street to avoid these conflicts 
>will be pressured to "use the path!"
>
>The problems this design creates outnumbers the problems it solves.
