Current road signs confront a fundamental issue: are signs displayed in different devices
(posted, on-board, painted or electronic) making the most of the same design rationale?
Convergent design principles help drivers enjoy an easier coding, learning and retrieval of
the schemes enhancing comprehension. This paper focuses on posted road signs (painted vs
electronic) that locate events and how well they complement each other. Fixed signage must
be the starting point (the scheme formed) to investigate how electronic devices (the new
information) can functionally locate variable events or situations.
The paper presents preliminary data regarding a sample of 39 participants. The experimental
task consisted of 27 blocks of traffic signs. Electronic-adapted traffic signs were shown to
all participants; however, only one group was exposed also to fixed (painted) signs. A 3x2
mixed design was used (experimental condition as inter-group factor and event location as
intra-group factor), and in addition, the design also included a working memory measure as
a covariate. Comprehension rates were high in all formulas of event location. As previous
studies, time response showed higher means when the variable event is located ‘between’
two referents. Moreover, ‘working memory (WM) span’ showed a marginal significance
with time response. This result leads to an interesting question about the consideration of
influence of individual differences in WM capacity when designing complex traffic
messages. Overall, results highlight the importance of understanding how complex traffic
messages are encoded, processed and de-encoded, and the limits human WM may pose.
