摘要:The use of assistance systems aimed at reducing road fatalities is spreading, especially for car drivers, but less efforts have been devoted to develop and test similar systems for powered two-wheelers (PTWs). Considering that over speeding represents one of the main causal factor in road crashes and that riders are more vulnerable than drivers, in the present study we investigated the effectiveness of an assistance systems which signaled speed limit violations during a simulated moped-driving task, in optimal and poor visibility conditions. Participants performed four conditions of simulated riding: one baseline condition without Feedback, one Fog condition in which a visual feedback was provided so as to indicate the participants when a speed limit (lower than that indicated by the traffic signals) was exceeded, two post-Feedback conditions with and without Fog respectively, in which no feedback was delivered. Results showed that participants make fewer speeding violations when the feedback is not provided, after one month, and regardless of the visibility condition. Finally, the feedback has been proven effective in reducing speed violations in participants with an aggressive riding style, as measured in the baseline session.
