One of the distinguishing features of future autonomous cars is the ability to take into
account and communicate with traffic infrastructure. Thereby detection and recognition of
vertical traffic signing is an obvious requirement. Automatic recognition of traffic signs allows
to check driver’s reaction time, if it is necessary to react, and in that way to contribute to and
increase the road safety. It is especially important in the darkness when the retroreflective
sheeting materials on the traffic signs help to increase visibility. Unfortunately, environmental
conditions around the traffic signs exert considerable influence on the sign’s surface and alter
their retroreflective properties. Many scientists explored different impacts on retroreflective
properties of signs. Some impacts attracted more attention (such as detection distances and
deterioration with age), some impacts were studied by several scientists only (such as dew and
frost) and some factors were even omitted at all (e.g. the temperature during measurements of inservice signs). The paper is focused on the impact analysis of insufficiently explored factors
influencing retroreflective properties of traffic sings. The findings of this research can support
the development of further experimental research and could become a basis of reliable traffic
signs usage on modern and smart roads.
