    The objective of this study was to assess the experiences of users before and after testing three selected systems in three iMobility Challenge events. The data was collected via questionnaires given to users - many of whom were experts in ITS or vehicle technology - who were testing the following technologies: emergency braking, Traffic Light Assistant and Park Assist systems. In total, 42 users participated in the demonstration and responded to the questionnaire. The results of the analysis indicated that the participants considered the systems more useful after than before the demonstration and were also more likely to pay for the systems after the demonstration. Participants' perceptions of the accuracy and timeliness of information provided by Traffic Light Assistant were higher after than before the demonstration, as were their perceptions of ease of use of the system.
