A thing that would work in at least the Netherlands, Belgium, 
Switzerland, Austria, Germany, France, Great Britain, Denmark, Sweden, 
parts of the US (and probably numerous other countries I never have 
visitied): Mark route reations with

     for the operation times

     for at least 6 services per hour on workdays from typical local
     breakfast time to one hour after typical local dinner time,
     3 services per hour on saturdays, sundays, and bank holidays

     if the service is subject to clock face scheduling

     if there is at least about one service per hour all over the day
     (again berakfast to after dinner)

     if the service has limited operation times (school buses, peak hour
     services, stadium extra service, night buses, and so on)

     as it exists. It is unfortunately ambiguous whether peak interval or
     longest interval is indicated, but people may like to continue
     information here

Using pairs of
with this or other suffixes can be given as advice for people who want 
to refine the information further.

Note that this information is usually stable for decades: It derives 
from the number of rolling stock divided per travel time. Lifetime of 
rolling stock is typically between 15 years (buses with internal 
combustion engines) and 25 to 50 years (trainsets), and 1:1 replacements 
are also quite common.

The rationale for breakfast to one hour after dinner is that both 
business and touristical activity take place within that time window.
People outside that time window will know how and where to get better 
adapted and more precise information.
