This paper summarises a report on the design and application of speed humps in the USA, that is being proposed as a recommended code of practice of the Institute of Transportation Engineers (ITE). The proposed recommendations are made in the following chapters: (1) introduction; (2) guidelines for speed hump use; (3) community relations and administrative procedures; (4) design and construction considerations; (5) monitoring and evaluation; (6) other considerations; and (7) source materials. There is a discussion of the differences between speed humps, which have a gentle profile, and speed bumps, which have a very sharp profile, and summarises the results of speed hump research and testing. Some factors are listed that have research and testing. Some factors are listed that have resulted in unsatisfactory experience of speed humps, followed by their removal. Monitoring activities and evaluation processes are identified and discussed, that are needed to understand fully the impact and effectiveness of hump use. Other issues include: (1) legal issues; (2) coordination between humps and pedestrian crossings; (3) incorporating humps in new street designs; and (4) the ability of humps to meet enforcement and maintenance needs.
