Fuel-efficient route choice

Fuel efficient route choice is a navigation system where optimisation of route choice is based on lowest total fuel or energy consumption instead of the traditional shortest time or distance travelled. The system is expected to take into account static information like trip length and speed limits. Also road gradients and curvatures can be taken into account, if such information is available. The most advanced version of fuel-efficient route choice would take into account dynamic real-time information about congestion and traffic incidents from probe vehicles or other sources.
