Development of the bases for the quantification of the effects of safety deficits and safety gains (VSS2005/302)
Overview
Background & policy context:
In the context of the development of the road safety audit procedure it showed up that together with the evaluation of the determined safety deficits/gains the quantification of the effects of these deficits/gains is appropriately on the road safety.
Thus a quantitative evaluation can take place, which indicates direct changes for the accident frequency and accident weight. It is also basis for a monetary evaluation.
Objectives:
The aim of this research was, based on known research reports, to search, to analyse and to develop tools for the quantification of the effects of safety-relevant differences and changes in context of a road safety audit.
Methodology:
Provision of the project results is made by a systematic evaluation of studies, expert reports, appraisals and literature documentation regarding quantified relationships between variables of the system and the traffic flow as well as other influencing factors and variables such as accident frequency, severity and types of accidents. A large selection of such documents is known. The desired relationships can respectively be filtered out by appropriate evaluations, analyses and calculations of the mentioned documents.
