Demonstration of another "old school" signal timing strategy intended for a grid of alternating one-way streets.

Annotations can't be added to videos now, so here are the offsets of all the intersections (in percent), west-to-east, on each street going from top to bottom:
{25, 0, 75, 50}
{50, 75, 0, 25} * seen in the initial view
{75, 50, 25, 0} * seen in the initial view
{0, 25, 50, 75}
