This paper presents the results of safety impact assessment, providing quantitative estimates of the safety impacts of ten ITS which were designed to improve safety, mobility and comfort of VRUs. The evaluation method originally developed to assess safety impacts of ITS for cars was now adapted for assessing safety impacts of ITS for VRUs. The main results of the assessment showed that nine services included in the quantitative safety impact assessment affected traffic safety in a positive way by preventing fatalities and injuries. At full penetration the highest effects were obtained for the systems PCDS+EBR, VBS and INS. The estimates for PCDS+EBR showed the maximum reduction of 7.5% on all road fatalities and 5.8% on all road injuries, which came down to an estimate of over 2,100 fatalities and over 62,900 injuries saved per year in the EU-28 when exploiting the 2012 accident levels adjusted with the estimated accident trends.
