Project Details

Title:Safety Effects of Protected and Protected/Permitted Left-Turn Phases
Principal Investigators:Juan C. Medina
University:University of Utah
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-495
RH Display ID:151197
Keywords:intersections, left turn phase, pedestrian flow, performance evaluations, permissive phasing, safety management, sight distance, signalized intersections, speed


The primary objective of this research project is to estimate the safety effects of left-turn phases for different conditions and provide operational recommendations. The operational recommendations will be in the form of a framework that demonstrates how the results of this research can be incorporated into a performance-based analysis of operational and safety trade-offs associated with different left-turn phasing alternatives.
