Why is the transport sector important?
Transportation is important for multiple reasons such as economic activity and mobility.

What else do we need to know to track efficiency in transports?
What is the split between passenger
transport and freight transport?
How much energy is spent in my country
to transport one passenger on a
distance of one kilometer?
Is it more intensive to travel in my
country – by bus, car or train?
How does it compare to other countries
in my region?

With additional data we can see where energy is used

5km + 5 km = 10 v-km
6 passengers * 5 km = 30 pkm
pkm/vkm = 30 / 10 = 3 p/v
