Traffic Signal Strategies for Oversaturated Conditions

项目名称：	Traffic Signal Strategies for Oversaturated Conditions
摘要：	Increasing traffic volumes are worsening congestion in Kentucky�s major population centers. On many arterials traffic demand exceeds capacity, restricting mobility. Standard signal timing practices, which seek to maximize greenbands through an arterial system, may not operate effectively during oversaturated conditions, due to queue spillback and blockages that can prohibit vehicles from arriving at downstream signals during the greenband. Several methods to address oversaturated signal timing methods have been proposed and used by others including gating, offset weighting, and reverse progression. While these methods show promise they also typically require extensive data collection and analysis. An efficient methodology is needed to let engineers identify and diagnose oversaturated conditions and implement countermeasures using current signal timing practices and available data.
