- 摘要：AbstractTo quantify the effect of unnecessary motorist hesitation in free right-turn channels and its impact on engineering delay models, the authors observed peak-hour operations at two free right-turn channelized intersections in Utah County, Utah. Regression analysis demonstrated that perceived vehicle conflicts would significantly increase individual vehicle delay at free right-turn channels, and that existing traffic prediction models did not adequately describe this delay. On average, motorists yield about 2seconds for each conflicting vehicle. This finding raises questions about the validity of current delay assumptions for free rightturn channels, or indicates the driving public may need more adequate signage. © 2011 Published by Elsevier Ltd.
