• Abstract:
  Modifying an existing intersection can improve both roadway performance and reduce emissions from vehicles moving through it. The Intersection Improvements Module of the Traffic Flow Improvements Tool estimates both performance metrics and emissions benefits for a single intersection for a project that: Installs a new traffic signal where a previous two-way stop or four-way stop existed before, Adds or modifies a signal’s turn phase (i.e., dedicated left-turn or right-turn signal), and/or Increases capacity by adding a left-turn lane at an intersection with a left-turn phase
