Evaluation of low cost traffic calming for rural communities : phase II.

The main goal of the research described in this report was to evaluate countermeasures that agencies can use to reduce speeds as drivers enter rural communities located on high-speed roadways. The objectives of this study were as follows: Identify and summarize countermeasures used to manage speeds in transition zones; Demonstrate the effectiveness of countermeasures that are practical for high- to low-speed transition zones; Acquire additional information about countermeasures that may show promise but lack sufficient evidence of effectiveness; and Develop an application toolbox to assist small communities in selecting appropriate transition zones and effective countermeasures for entrances to small rural communities. The team solicited small communities that were interested in participating in the Phase II study and several communities were also recommended. The treatments evaluated were selected by carefully considering traffic-calming treatments that have been used effectively in other countries for small rural communities, as well as the information gained from the first phase of the project. The treatments evaluated are as follows: Transverse speed bars; Colored entrance treatment; Temporary island; Radar-activated speed limit sign; and Speed feedback sign. The toolbox publication and four focused tech briefs also cover the results of this work.
