Blackspot remediation and options for improving the process

This article discusses how blackspot programs have produced positive safety benefits over the years. The cost effectiveness of these programs is also presented in the article. The article notes that because of the criterion for identifying a site as an accident blackspot is typically so small of a number that the selection of sites by this means gives different results from one time period to another. Some ways in which the blackspot remediation process might be improved are also discussed. There is a shortage of credible indirect measures of risk or safety other than speed and the development of such quantities would greatly improve the understanding of how safety varies on the highway network.
