Traffic management

Traffic management  - Energy efficiency optimised intersection control

The traffic management element of FREILOT will optimise the traffic control system to reduce heavy vehicle fuel consumption.

The fuel consumption of a motor vehicle is determined by its speed and acceleration. In urban areas speed is of lesser importance while acceleration, due to many stop-go cycles or slowing at intersections and roundabouts, is the main factor responsible for high fuel consumption.

Optimising traffic control for maximum fuel efficiency would aim to minimise congestion and vehicle stops at signal-controlled intersections and roundabouts.

To achieve this goal several innovative measures are implemented to locally improve coordination and avoid heavy goods vehicle stops through selective detection (by size or by vehicle/fleet identity) and priority at individual signalised intersections.
