*Informe “Practices in One-Lane Traffic Control on a Two-Lane Rural Highway TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 525: Practices in One-Lane Traffic Control on a Two-Lane Rural Highway identifies innovative practices and devices for establishing one-lane traffic control on rural two-lane highways. Temporary traffic control, also known as maintenance of traffic, is critical to minimizing congestion and maintaining mobility during planned and unplanned activities as well as providing a safe work zone for both road users and workers. Innovative examples of one-lane two-way traffic control operations at roundabouts and applications of temporary portable rumble strips and driveway assistance devices are also discussed in this synthesis, providing additional insights on the state of the practice.”:

*Informe “Evaluation of Innovative Approaches to Curve Delineation for Two-Lane Rural Roads The Virginia Department of Transportation has released a report that examines the effectiveness of a variety of active and passive curve warning and curve delineation systems on two two-lane rural roads to determine which is the most effective at reducing vehicle speeds and assisting lane-keeping. Run-off-road crashes are a major problem for rural roads, which tend to be unlit, causing drivers to have difficulty seeing or correctly predicting the road curvature.”:
