  • 1. DRAFT 2pi™ Traffic System Feasibility Study© Two Phase Enhanced At-Grade Intersection™ 2pi™ Evaluation Study - Findings & Conclusions. In order to evaluate the 2pi™ Traffic System effectiveness and applicability, a series of comprehensive traffic operations and comparisons were performed utilizing as baseline data on previous studies. These base studies are the Traffic Impact Study (Draft) Version-1 of August 24, 2006 and the Priority Treatment Plan (Final) of August 24, 2006 prepared by: STV Incorporated in association with: City Works, Katz & Associates, Katz, Okitsu & Associates, Teshima Design Group and URS Corporation. Naturally, methodologies applied in the studies vary. Therefore, only final results were considered when performance and measures of effectiveness (MOEs) were compared. As explained in the methodology chapter of this study two main, among others, traffic operation analysis software was utilized: the Static: Highway Capacity Manual (HCM) and the Dynamic: VisSim™, a visual language for mathematical modeling and simulation. At the core of this study is the critical PM peak hour traffic, transit and pedestrian operations forecasted for the targeted year 2030. Ten intersections along the identified segment on Nobel Drive from Lombard Place (ID. #1) in the east end to Villa La Jolla Drive (ID. #10) on the west end of the Super Loop are included in this study.

  • 2. DRAFT 2pi™ Traffic System Feasibility Study© Two Phase Enhanced At-Grade Intersection™ 2pi Geometry and Operative Characteristics: The “typical” Intersection: In a typical four phase two way street intersection geometry, vehicles are queued in three phases, and move only in one. Left turns have a significant impact on the operation and performance of signalized intersections. The conflicts between left and through traffic movements yields low capacity and poor coordination, increasing delays and emissions. Pedestrian crossings further increase the points of conflicting, additional phases are required in order to provide pedestrian crossings with an acceptable level of safety. The Two Phase Enhanced At-Grade Intersection™ System (2pi) The 2pi™ unique characteristic is the physical treatment and time management of vehicles and pedestrians. Conflicts of opposing left turn movements are eliminated by crossing the left queuing vehicles lanes on the left side of the road at all four approaches prior to the intersection. This is achieved when cross road traffic is moving, at that time vehicles turning left queue in four advance crossing points. Left turners are transited to the left side of the road, crossing the opposite through traffic lanes without conflicting traffic flow. Then vehicles proceed to travel parallel and simultaneously to opposite oncoming through traffic lanes. After queuing, during only one phase, vehicles complete the left turn connection unobstructed. Pedestrians, through traffic, and right-turn vehicles negotiate the intersection without left turn conflicts, which were previously diverted. The same replicates in all four approaches. These among others physical, geometric and operational characteristics define the differences between the “standard/typical” geometry at intersections and the “2pi™” traffic system. Improvements in performance, capacity and overall traffic management as well as environmental impacts are considerable. This first assessment study in a build-up urban area like University City in La Jolla and in particular along the Super Loop Transit Project allows for the review the 2pi in a vast universe of space-geometric constrains and traffic operation conditions. Based on preliminary conceptual design it yielded valuable measurements of effectiveness and applicability in a specific studied project. The opportunity to compare the results of this 2pi™ study with recent and comprehensive studies like the Traffic Impact Study (Draft) Version-1 and the Priority Treatment Plan previously mentioned constitutes an added value. The following summarized findings, measures of effectiveness (MOEs,) LOS, Travel Time Savings, graphics and tables depict the results of this study and a comparison report with data from the previous studies as baseline.
