Visual Feedback Effectiveness in Reducing Over Speeding of Moped-Riders Tagliabue, Mariaelena Di Stasi, Leandro Luigi Moped-riding simulator Alert feedback Active warning systems Two-wheel drivers Long lasting learning effects The use of assistance systems aimed at reducing road fatalities is spreading, especially for car drivers, but less effort has been devoted to developing and testing similar systems for powered two-wheelers (PTWs). Considering that over speeding represents one of the main causal factors in road crashes and that riders are more vulnerable than drivers, in the present study we investigated the effectiveness of an assistance system 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 visual feedback was provided so as to indicate to the participants when a speed limit (lower than that indicated by the traffic signals) was exceeded, and 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 1 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. 2021-04-14T10:38:00Z 2021-04-14T10:38:00Z 2021-03-11 journal article Tagliabue M, Rossi R, Gastaldi M, De Cet G, Freuli F, Orsini F, Di Stasi LL and Vidotto G (2021) Visual Feedback Effectiveness in Reducing Over Speeding of Moped-Riders.
