A two-phase signal system is installed at the intersection described in Problem 8-1, with channelized left-turn lanes and shared through and right-turn lanes. Using a suitable diagram, determine the possible conflict points. Indicate the phasing system used.
What will be an ideal response?
The recommended phasing for the intersection configuration shown below
consists of two phases: one for westbound traffic (left and through, one for
westbound traffic (through) and eastbound traffic (through-right), and one for
