    Impacts of two EasyWay core services for traveller information, travel time services and co-modal services were analysed by the EasyWay VIKING evaluation group in 2012. The goal of the synthesis was to find out how extensively the services have been analysed, and what the main impacts are. European databases, such as 2DECIDE, and national evaluation databases were used to collect the relevant ex-post impact evaluation studies. The analysis included altogether 17 travel time services and five co-modal information services. In general, better network distribution was reported due to travel time information services. Three of the analysed studies on VMS impacts reported on similar driver diversion rate of about 25% in case of long delays on the main route. Overall, EasyWay was really lacking impact results of co-modal (including both private and public modes) TIS. The analysis of impacts was based on only five found ex-post evaluation studies
