N2  - Seventy-three local government traffic engineers in Melbourne were shown a film of 27 traffic sign installations and asked to judge whether, in their opinion, the sign was required at that particular location. The level of consistency in the responses was the primary aim of the study, plus the relationship, if any, to response measures found in previous studies. Respondents were, for most sites, inconsistent in their responses, i. e. not in agreement as to the need for a sign. In addition, there appeared to be a bias in that many respondents tended to nearly always respond 'yes' or 'no' for all signs presented. A detailed analysis of the responses showed that Indicated Level of Response, a measure of perceived necessity for the sign, was not significantly correlated with the Reported Level of Sign Information, i. e. the ratio of driver responses mentioning correct sign information to the total number of reports for that site.     <p>Language: en</p>
