Abstract

[automatically translated] Even in Italy, as happens in other countries for decades, variable message signs (VMS) are finding an increasingly wide dissemination, both in urban and suburban; they let you send, in real time, information of any kind to motorists passing along the streets where these panels are placed. The messages cover news concerning the state of the roads (congestion conditions, roadblocks to accidents, road works) and various information (tourist signs, updating news, advertisement, ect.). The memory shows the results of a joint research that the University of Cagliari and Brescia have developed on the issues of road signs, analyzed through the application of the principles of the discipline of human factors. In the application presented here, it has been evaluated the quality of perception of messages, sent via PMV, by a set of surveyed drivers immediately after the transit below the panels. Data were analyzed using multivariate techniques, which have allowed the identification of the main variables that influence the perception by drivers. In particular there was the goal to reach the definition of the PMV management mode through the identification of more effective rules of textual composition of the message. The results have highlighted how these messages are, in general, little read and understood by drivers, because not always the structure and composition of the text shown in the device satisfies the basic criteria of the discipline of human factors. This is compounded by the fact that almost always the PMV are kept constantly active without immediate interest to send messages (such as, for example, greetings, penalties for infringements, general notices on the Highway Code), creating a kind of lack of interest in reading for addiction to useless information. The analysis, however, result as a sparse text and with few indications may prove more effective and comprehensible to the user. Directions pleonastic in the message, although supported by copious bibliography, have complicated and made more difficult to read and the subsequent storage of the message. penalties for infringements, general notices on the Highway Code), creating a kind of lack of interest in reading for addiction to useless information.
