Almost every community planning document stresses the need to achieve a mode-shift away from the private automobile towards a more sustainable and equitable transportation network. That's easy if you're starting from scratch, but in established locations less so. With endless money, and no regard for neighbouring residents, its also easy, but how do we go about de-prioritizing the car, with little money, without changing the road footprint. Here are two concepts close to my home along with some notes...
The Existing Condition
Partially Protected Bike Solution
Fully Protected Bike Solution
Which Would you Choose?
It will take a lot of courage to implement the fully protected option and restrict existing vehicle movements much more than at present, but this is what it will take across a wide network to make cycling truly safe enough for all ages and abilities.
In this case, I think the partially protected solution would be easier to "sell", but it still present concerns for inexperienced cyclists. Its a huge improvement on the existing condition but may may not attract the ridership of the truly protected solution. Cyclists could still make the two stage left turns by illegally using the pedestrian crosswalks and sidewalk corners for safe refuge.
