Safety Evaluation of Continuous Green T Intersections

CHAPTER 3. OBJECTIVES

The objective of the present study was to examine the safety effectiveness of CGT intersections in terms of crash frequency using a rigorous methodology. The propensity scores-potential outcomes framework described by Sasidharan and Donnell was used.(9) In this analysis, the safety performance of CGT intersections was compared with the safety performance of traditional, signalized T intersections. The following target crashes were included in the evaluation:

The 250-ft measurement was defined by Harwood et al. as the boundary for intersection-related crashes when assessing the safety performance of left- and right-turn lanes at three- and four-legged, stop- and signal-controlled intersections.(10)
