Road authorities regularly call for the provision of traffic impact studies (TIS) in order to assist in obtaining sufficient information to make decisions. The purpose of a TIS is to assess the effects of traffic caused by a proposed development and to identify improvements that may be required in order to ensure that the roadway system will operate at an acceptable level upon completion. Traffic impact studies concentrate on the evaluation of the operational impacts. However, one issue that is not generally explicitly addressed in a TIS is safety. This paper describes the development of safety impact study guidelines that have been completed for the Regions of Halton and Niagara in Ontario, Canada. The paper reports on methodologies by which the safety impacts of proposed developments can be assessed and offers commentary on how safety impact studies compliment traffic impact studies. It highlights how safety impact study guidelines are used to examine safety aspects of development submissions. For the covering abstract of this conference see ITRD number E211395.
