I misspoke and attributed the study of traders' perceptions of their customers mode of transport to the Irish Cycling Campaign. In fact, the Shopping Travel Behaviour in Dublin City Centre Survey (http://arrow.dit.ie/cgi/viewcontent.cgi?article=1035&context=civpostbk) was done by DIT and shows that traders overestimate the proportion of their customers who travel by car and underestimate the proportion who travel by foot or by cycle.
