If the road is wide, (two or more traffic lines per traffic direction) and a central reservation exists or can be provided, traffic signals can be installed in a not aligned pair. This design permits to provide staggered green time for pedestrians (one side can be green while the other is red), The pedestrian needs to wait in the central reservation for the second crossing, improving the possibility to coordinate vehicle traffic between intersection, with a reduction of stops, fuel consumption, and reduced car emissions.
