Increasing Intersection Capacity and Safety Through Innovative Intersections: Success Stories

Abstract: In the realm , the conventional approach of enhancing intersection and roadway capacity has been typically performed through major widening. However, creativity and innovation can yield significant savings in terms of right-of-way, utility, and construction costs. Particularly, our attention is drawn to the most problematic roadways characterized by high traffic signal density and all movements under signal controll. Amidst a diverse array of innovative intersection designs, a singular commonality emerges: the elimination of left turn phases from traffic signals. This seemingly simple alteration results in remarkable changes, redistributing substantial green time to vital through movements. Through compelling examples, this presentation illuminates the profound impact of eliminating traffic signal phases, showcasing its efficacy in comparison to the traditional approach of expanding pavement, revolutionizing intersection optimization strategies at constrained locations.
