examples can support accident commissions and
decision makers supporting the assessment of
advantages and disadvantages of a planned
measure. It shows alternative possibilities and also
presents not suitable measures. The collection of
examples can additionally be used by road safety
auditors for the judgement of safety deficits in
planning.
The collection of examples could be downloaded on
the website of the Federal Highway Research
Institute (www.bast.de).
For the data collection nationwide 65 accident
commissions were contacted. 110 accident black
spots were selected and presented in the collection
of examples. The analysis showed that road
construction measures on average have a higher
measure impact, can reduce more accidents (and
personal injury accidents), avoid higher accident
costs and the effects are more significant than of
traffic engineering measures. Mostly road
construction measures can be used efficiently but
due to the high costs they mostly show a lower
benefit-cost-ratio in comparison to traffic
engineering measures.
The appendices in the original report include the
questionnaires used (Appendix 1), an overview of
the standard accident costs (Appendix 2) and the
costs of measures (Appendix 5), tabularizations of
deficits (Appendix 3) and measures (Appendix 4),
as well as a grouping of summary analyses of
effectiveness of measures and accident
development. Reproducing these appendices in the
existing publication has been rejected. They are
published in conjunction with the collection of
examples for the existing project on the webpage of
the Federal Highway Research Institute
(www.bast.de). References to appendices have
been maintained in the report for the information of
the reader.
