TitleBlackspot remediation. Part 2: Options for improving the process [DRAFT]
AuthorsHutchinson TP
Year2012
TypeJournal Article
AbstractPart 1 of this paper noted that because the criterion for identifying a site as an accident blackspot is typically so small a number, 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 discussed. (The empirical Bayes method. Randomised trials. Administrative processes. Should the evidence from the crash record and from the site inspection be more independent? Geographical databases as a source of characteristics of crash sites.) It may be better to increase the weight given to expert judgment, assisted by objective measurements of traffic and perhaps by a formal process of safety audit. There is a shortage of credible indirect measures of risk or safety other than speed: development of such quantities would greatly improve the understanding of how safety varies over the road network.
