NCHRP Synthesis 381

STE developed a Falling Weight Deflectometer (FWD) Usage Synthesis for the National Cooperative Highway Research Program (NCHRP). These devices are used to measure pavement deflections in response to a stationary dynamic load, similar to a passing wheel load. The data obtained are used to evaluate the structural capacity of pavements for research, design, rehabilitation, and pavement management purposes.

Montana Department of Transportation (MDT) Ride Specification Review

STE reviewed MDT ride specification for flexible pavements and compared it with current literature and state-of-practice. An extensive survey of other Departments of Transportation (DOTs) was conducted and the results were utilized to provide recommendations to MDT for improving its ride specification.

Traffic Calming Guidelines

Many agencies are developing guidelines and policies for traffic calming. Traffic calming is a methodology to influence motorist behavior and prevent undesirable driving practices. Traffic calming is generally achieved with physical measures that reduce vehicle speeds, reduce traffic volumes, discourage through traffic on local streets, minimize conflicts between street users, and enhance the environment. The City of Sparks, Nevada, was interested in applying appropriate traffic calming with the goals of improving neighborhood safety and livability. This guide presents recommended traffic calming guidelines for the City of Sparks. The guidelines are applicable to new developments and existing neighborhoods. The guidelines contain descriptions of traffic calming measures, recommendations for use of specific traffic calming measures and recommendations for design of traffic calming measures.
