Dynamic Traffic Management 12 June 13 th, 2006 Dynamic Route Information Panels since 1990
Dynamic Traffic Management 13 June 13 th, 2006 Dynamic Route Information Panels since 1990 • For: – on route information – major incident information and response • Several assessment studies: – In 'normal' conditions, 8 -10% of drivers reacts on information – Network performance may increase with 0 -5% – Drivers satisfied, more comfort, less stress • Different implementations and tests: – Queue length – Traveltime – Graphical
