abstract="The techniques of cost-benefit analysis are used to develop a method for determining criteria for the introduction of traffic accident countermeasures. The method which, with suitable variations, can be applied to a range of problems, is described in general terms and an example is presented of the application of the method to the determination of the need for median barriers on a divided highway. The example provides data which are consistent with the warrant devised for the NCHRP in U.S.A.<p />",
