Conversion from night-time flash back to regular phasing seems effective in reducing night-time crashes.

WebbProtected only left-turn phases may reduce delay for turning vehicles but are likely to increase overall intersection delay. Protected-permissive left turn phases can offer a good compromise between safety and efficiency but could limit available options to maximize signal progression during coordination unless innovative displays are used. WebbThis paper presents a new approach for developing guidelines for the installation of a protected left-turn phase at signalized intersections when permissive-only left-turn operation is present. The goal of the approach is to maintain intersection traffic operation at optimum efficiency. Three analyses are presented and discussed.
