Apart from the direct effects, it should be noted that the sum of all
these time periods shows the delay imposed on a bus by a bus stop.
This in turn affects the commercial speed of the bus service – the
distance divided by the total travel time between any two points
of the route – because it adds to the time taken to operate from the
start to the end of a bus route.
