Speed Management Safety Website â¢ Source: https://safety.fhwa.dot.gov/speedmgt/. â¢ Date: last modified April 2019. â¢ Publisher: Federal Highway Administration. â¢ Description: This website provides links to several publications and tools along with ongoing research. Speed Management ePrimer for Rural Transition Zones and Town Centers â¢ Source: https://safety.fhwa.dot.gov/speedmgt/ref_mats/rural_transition_speed_zones.cfm. â¢ Date: January 2018. â¢ Publisher: Federal Highway Administration. â¢ Description: The Speed Management ePrimer for Rural Transition Zones and Town Centers reviews speeding-related safety issues facing rural communities and discusses the basic ele- ments required for data collection, information processing, and countermeasure selection by rural transportation professionals and community decision makers. The ePrimer is presented in six distinct modules developed to allow the reader to move between each to find the desired information, without a cover-to-cover reading. Traffic Calming ePrimer â¢ Source: https://safety.fhwa.dot.gov/speedmgt/traffic_calm.cfm. â¢ Date: FebruaryÂ 15, 2017. â¢ Publisher: Federal Highway Administration. â¢ Description: The ePrimer presents a review of traffic calming practice in eight modules. The ePrimer presents: â A definition of traffic calming, its purpose, and its relationship to other transportation initiatives (like complete streets and context-sensitive solutions). â Illustrations and photographs of 22 different types of traffic calming measures. â Considerations for their appropriate application, including effects and design and instal- lation specifics.

The document contains strategies based on research related to managing speed through setting and enforcing speed limits and guidance on reducing speeding-related crashes. The document includes specific goals, objectives, and action items for speed management. The report also includes priority areas that transportation professionals are encouraged to focus on. However, over the past 5Â years, the topic has evolved to the extent that specific content for each of these elements needs to be updated. A recent FHWA study is developing an updated version.

Guidance for setting speed limits is provided, and case studies are included. The guidance also discusses speed zones including advisory, school zones, work zones, variable speed limits, and transition zones. This includes guidance for when speed transitions are needed and the setting of transition zone speeds.
