Implementation of wider lane lines to improve sight distance from opposing left-turn lanes
PS Byrd, PT McCoy, G Pesti… - Transportation research …, 2000 - journals.sagepub.com
Vehicles turning left at intersections from opposing left-turn lanes often restrict each other's
sight distance. Previous research has developed guidelines for offsetting opposing left-turn
lanes to provide adequate sight distances. Implementation of these guidelines at existing
intersections typically involves reconstructing the left-turn lanes. However, the results of the
before-and-after studies presented demonstrate that increasing the width of the lane lines
between left-turn lanes and the adjacent through lanes also can be used as a means of …

Sight distance availability is an important factor affecting safe traffic operations at
intersections with unprotected left-turn movements. In such situations, drivers must choose
adequate gaps in the opposing through traffic stream to complete left-turn movements.
These left-turn movements can be further complicated by the presence of opposing left-turn
vehicles. The opposing left-turn vehicles can greatly reduce the left-turn sight distance
available. The University of Nebraska-Lincoln, in cooperation with the city of Lincoln, city of …
