Dynamic Speed Control
Speed is a critical factor to consider when looking at how vehicles fill available road capacity.
Legal speeds are determined largely with safety in mind. However, on urban roads and mortorways,
speed has an incidence on traffic flow. On crowded roads, sudden decelerations, uneven accelerations
and differences in individual vehicle speeds can all trigger congestion. Slower, more even speeds and
less erratic driving behaviour can all increase flows on roads while avoiding or postponing sudden
flow discontinuities.
