The phase 1 of the VeSPA research package “road safety gains resulting from datapooling and structured data analysis" has been terminated and the reports of the five subprojects as well as the final synthesis report are established. The results of the first phase led to a focused design of phase 2 on measures and potentials with a concentration on only two subprojects. The main goal of the research project "Research Package VeSPA: TP1-M Measures and potentials in the field of road users" is to combine the factors that affect accident events and to detect interactions among those effects in order to formulate measures to increase the safety on roads in Switzerland. The groundwork is based on structured data analysis on the VeSPA data set.
