Managing Speed on Low-Speed Urban Streets

Sunday, January 07, 2018, 9:00 AM-12:00 PM, Convention Center 2018
Eric Donnell, Pennsylvania State University; Hermanus Steyn, Kittelson & Associates, Inc. (KAI), presiding
Sponsored by Standing Committee on Geometric Design; Standing Committee on Operational Effects of Geometrics; Standing Committee on Access Management; Standing Committee on Highway Safety Performance; Standing Committee on Traffic Law Enforcement; Standing Committee on Pedestrians; Standing Committee on Bicycle Transportation; and Standing Committee on Public Transportation Planning and Development

Urban streets are designed to offer accessibility and safety for all users, so low posted speed limits often are established to facilitate these objectives. Operating speeds on these streets often exceed the posted speed limit, however. This workshop introduces the topic of target speeds to urban street design so that operating speeds are consistent with the posted limit, roadway context, and modal mix. Quantitative tools to achieve these objectives will be introduced, along with a case study.
