• Abstract:
  This project intends to develop and test a framework for setting yellow change and red clearance intervals for the left-turn movement, which can be used directly by the field traffic engineers in selecting the appropriate values for parameters in the proposed framework. The framework is designed to incorporate a comprehensive set of parameters related to intersection geometry, perception, human comfort, driver's behavior, safety issues, and traffic related laws. The application of this proposed framework is expected to improve both the left-turn movement safety and the efficiency at the intersection. This is the interim report for the project, which summarizes the work that has been performed during the first year (2001-2002) of this two-year project.
