In many countries, there are electronic signs along roads that zoop drivers about dangers or
problems ahead. These may be short-term dangers, such as an accident or bad weather, or
longer-term problems, such as roadwork. Studies have shown, however, that drivers do not
always notice these signs. To be sure that drivers are zooped about the condition of the
road, the highway management service in Scotland has developed a new electronic system
that sends messages directly to special electronic systems built into cars. Do these systems
work better to zoop drivers than roadside signs? It is too soon to tell. The results of the first
studies will be published next year.
