• Abstract:
  The Federal Highway Administration (FHWA) organized 26 states ; to participate in the FHWA Low-Cost Safety Improvements Pooled ; Fund Study as part of its strategic highway safety plan support ; effort. The purpose of the study is to evaluate the safety effectiveness ; of several low-cost safety improvement strategies through ; scientifically rigorous crash-based studies. One of the strategies ; evaluated for this study was the installation of center two-way leftturn ; lanes (TWLTLs) on two-lane roads. This strategy is intended ; to reduce the frequency of head-on crashes and rear-end crashes ; involving a turning vehicle. The safety effectiveness of this strategy ; has not been thoroughly documented previously; therefore, this ; study is an attempt to provide an evaluation of TWLTLs through ; scientifically rigorous procedures.
