Separate Left-Turn Phase Alternatives Study


The current evaluation process is limited in its scope and addresses only those locations with an existing dedicated left-turn pocket.  Many existing locations cannot accommodate a separate left-turn only lane without using an existing through lane or taking additional right-of-way.  In cases where this is impractical, a method needs to be developed to evaluate locations to determine if installing a left-turn phase with its sometimes negative affect on through traffic is feasible.
