• Abstract:
  In this project, Florida International University researchers had a primary goal of evaluating the safety impact of converting two-way left-turn lanes (TWLTLs) to raised medians. On the face of it, such a conversion would have an obvious, positive effect on safety; however, configuration changes on one section of a roadway can have an unexpected effect on adjacent sections. In addition, the presence of medians changes how people access local businesses and how businesses receive and send out shipments. Therefore, the researchers evaluated a number of effects of conversion to gain a larger picture of its impact.
