New Urban Streets - Fused Grid
The new urban reality is that cars are both necessary and, at times, undesirable.
Large, dense cities with high traffic volumes are opting for a new urban street type - pedestrian - and its close relative, managed vehicular acess only.
New technology comes to their aid; retractable, card activated bollards.
This combination produces a fused grid (see Wikipedia and photostream)configuaration: regular streets for all modes and special streets that are preferencial to pedestrian movement and enjoyment.
