The objectives of the study were to develop guidance for the design of offset left-turn lanes used as a safety countermeasure, and to provide insight regarding the use of the NDS data to future users.application/pdfen-USIn CopyrightCritical gapAccepted gap lengthRejected gap lengthSafety surrogatesOffset left-turn lanesLogistic regressionPresentationhttp://www.apps.vtti.vt.edu/PDFs/ndrs-2014/Bauer-2014.pdf
