Traffic Calming and Speed Reduction on Rural Highways in Population Centers

Current practice for setting or amending speed limits on rural highways through population centers is to conduct a speed study and set the limit based on the observed behavior of drivers. When residents request a review of the speed limits in hopes of a speed reduction through their area to improve safety or increase the perception of safety, Nebraska Department of Transportation's (NDOT’s) hands are currently tied without justification or precedent to lower the speed limit beyond the 85th percentile speed observed. This research is intended to broaden the set of tools available to NDOT to design and implement traffic calming treatments on two- and three-lane highways in rural communities. Preferred treatments for use by NDOT will be identified, some of these treatments will be implemented in the field, and case study data specific to Nebraska will be obtained. As part of the work to produce the final report for this project, deliverables will include generating details and standard plans for use on future projects, as well as the generation of informational brochures for use by NDOT when communicating with residents.
