New research by academics at the University of East Anglia (UEA), University of Kent and University of Lincoln, suggests that insights from behavioural science can help inform the design of road signs to bring about changes in driver behaviour.Research in behavioural science has demonstrated how even very minimal cues or ‘nudges’ can sometimes have a powerful influence on human behaviour and decision-making. In this study, the researchers applied this approach to examine whether simple visual and written cues could be used to encourage drivers to switch off their engines while waiting at railway crossings.
