Successful implementation of bridge operator solution in Drechtsteden (Holland)
Ferranti has successfully delivered a solution for the bridge operators of Prins Hendrikbrug in Drechtsteden (Holland). The bridge operators are responsible to open the bridge when a ship wants to pass through, effectively stopping all traffic crossing the bridge. Public transport buses also end up in the queue which causes delays.
The solution uses the same real-time information of the buses that is used for displaying information to travelers. A screen displays the upcoming passage of buses that cross the bridge. The displayed information is specifically designed for the bridge operators (only the necessary information and using colors) so they can see in a glance whether they should wait with opening the bridge or not.
Recently a study was performed with cameras to measure the effect of this information panel on the delays of the buses crossing the bridge: The number of buses arriving within two minutes of opening the bridge, has reduced from 47% to 22%, showing a significant reduction of waiting time for the passengers.
A short movie that was broadcasted on regional television, shows the screen in action:
