With the integration of the Road Traffic Accident Register in the Management Information System for Roads and Road Traffic (MISTRA) of the of the Swiss Federal Roads Office (FEDRO), it is possible to link accident data with data of other FEDRO registers. This newly created pool of data allows detailed analysis of various factors on accident rates. The proposed research package “road safety gains resulting from datapooling and structured data analysis" consists of 7 sub-projects and is divided into two phases. The scientific sub-projects examine the fields of persons/society, situation/infrastructure, vehicle, weather, medical consequences and economic costs.
Main results of the subproject 005 are quantified relationships between weather and road accidents. As a first step, the existing data will be analyzed and improved with respect to their relevance to the topic. Relevant indicators will be prioritized in a multidisplinary team. Potential interdependencies between individual variables are analyzed and evaluated on the basis of indicator variables according to their statistical relationships.Thereafter, the statistical correlations are evaluated by meteorological and road traffic experts.
The found results will be prepared for re-use and documented in the research report, which includes a description of the underlying methods. At the data level, a comprehensive meteorological data will be developed, which includes spatially and temporally distributed data about sunrise and sunset.
