Abstract:

This report reviews an Oregon research effort to identify ways to calm operating speeds as the vehicles transition into developed suburban/urban areas from rural roads. Drivers of vehicles approaching the urban environment have few visual cues to reduce their speeds until their vehicles are well into the more urban environment. This report specifically reviews a simulator study for rural-to-urban transitions. The study included two pilot studies and one full scale study. The scenarios evaluated were ones that either physically or perceptually narrow the road at these transition locations. The specific transition treatments included in the full scale simulation were:

•Layered landscape

•Gateway with lane narrowing

•Median treatment only

•Median with gateway treatment

•Medians in series with no pedestrian crosswalks

•Medians in series with pedestrian crosswalks.

Though all enhanced speed reductions were minimal, the scenarios with the most effective speed reduction results included the median treatments (particularly the medians in a series or the treatment combined with a gateway). The layered landscape treatment and the gateway with lane narrowing treatment did not result in statistically significant speed reductions.
