Overview

This High-level Function shall plan the road based portions of trips.  It shall use road network and regular traffic information, plus weather and traffic perturbation information. If the trip is for HGV or freight vehicles the Function shall take into account route restrictions.  Any restrictions dictated by the cargo type (tunnels, residential areas, etc.) shall also be considered.  For emergency vehicles a detailed route and schedule shall be produced in the form of a 'green wave'.  Road trips for cyclists and pedestrians shall be produced by the Function using the road network data and related perturbations, but disregarding traffic incident information.
