Expectations We expect to get a quantitative analysis of this
intersection during its peak hour We expect ~5% of the vehicles to
make a U- Turn on Cumberland We expect a minimum wait time of 2
light cycles to get through the intersection

expected. The majority of vehicles sat through a maximum of 1
cycle.
