Is Age a Factor in Crashes at Channelized Right-Turn Lanes?

Several documents, including the recently published Federal Highway Administration 2014 Handbook for Designing Roadways for the Aging Population, states that older drivers have difficulties in turning their head to see upstream gaps in a merge situation. The objective of this study is to determine the relationship between crashes and channelized right-turn lane geometric characteristics with a specific consideration of the age of the driver.
