In response, the DDOT\u2019s Research Program led the development of DDOT\u2019s Traffic Calming Policies and Guidelines to assist in understanding residential traffic issues and, where appropriate, do something about them, all with the broader goal of neighborhood livability. The policies and guidelines, and the Traffic Calming Program it created, was a product of a coordinated effort among HUTRC staff, DDOT officials, Advisory Neighborhood Commission (ANC) representatives, and residents of the City. The handbook outlines the traffic calming process, from requests to implementation to monitoring. However, it does not provide guidelines for design and installation purposes. Specific details including possible height, width, slope, signs, etc., of traffic calming measures (TCM) needs to be developed for implementation in the City. The design guidelines will be a resource to design engineers as they consider the best solution to traffic calming problems on a case-by-case basis. In developing this document for the District of Columbia, HUTRC reviewed existing and available traffic calming design guidelines from other jurisdictions. The guidelines also took into consideration both national (e.g., MUTCD) and the City\u2019s local design standards and guidelines.133
