Guidance lamellas are part of tourist information signs, which are positioned mostly on the
roads in urban areas with the purpose of guiding to important buildings and tourist
destinations. They are set up in sets, up to seven guidance lamellas in the individual set at the
most.
Slovenian regulations comprise of only general provisions regarding guidance lamellas, which
are definitely in sufficient for establishing a unified lamellar system throughout the country.
In the MSc Thesis were above all on the basis of rules of perceiving traffic signs (human
factor) by the participants in road traffic studied and proposed practical solutions for the
following segments of the guidance lamellas: shapes and sizes, fonts, direction arrows and
symbols. Grey colour for guidance lamellas with commercial contents has also been defined.
For 50 symbols, legislated for the use on the guidance lamellas, the verification was
performed by a survey to verify their recognition among the drivers in Slovenia. The finding
indicates that certain symbols should be changed or even abolished.
The maximum permissible number of guidance lamellas in the individual set, which enables
adequate perception to the driver has also been verified. The verification was done by
theoretical method and time measurements of drivers reactions in the field.
