Study: “Shared Space” Slows Drivers While Letting Traffic Move Efficiently
The idea behind "shared space" street design is that less can be more. By ditching signage, traffic lights, and the grade separation between sidewalk and roadbed, the shared space approach calms traffic and heightens communication between drivers, pedestrians, and cyclists.

Highway Boondoggles: Widening I-95 Across Connecticut
Last year Congress passed a multi-year transportation bill. Like previous bills, it gives tens of billions of dollars to states every year to spend with almost no strings attached.
