Decision-Making Guide for Traffic Signal Phasing
Few resources provide information related to selecting the most appropriate traffic signal
phasing for the
various geometric and operational situations encountered in the field. This is especially true
for left-turn
signal phasing decisions with respect to the level of control for the left-turn movement
and
whether left turns should precede or follow the main through movement.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 284:
Decision-Making Guide for Traffic Signal Phasing
is designed to give professionals designing or operating
signalized intersections the tools they need to provide safe and efficient overall operations,
considering
both crash risk and movement delays.
