Examples of UTMC in Action
Local authorities with UTMC have more control over their road network. Some examples of what they can do are:
Advise
By monitoring how long it takes a vehicle to pass two ANPR cameras and then dividing the time by the distance between the cameras, an average speed can be measured and used to inform motorists via VMS how long it will take them to reach a destination, or to set diversions. Example by Envitia: VMS in Aberdeen . Example by IDT: Car park counting in Aberdeen
Warn
Wind detectors attached to a bridge give drivers of high sided vehicles warnings before they cross. The warning messages are displayed on VMS signs activated when wind speed thresholds are exceeded. Example by Siemens: Bridge VMSs offer wind warnings .
Guide
By linking parking guidance systems to a common database traffic control room operators can inform motorists via strategic VMS about the current state of car parks; especially useful for special events like carnivals when normal use is exceeded. Example by Motts MacDonald: Car Park Guidance in Edinburgh
Previously these systems would have been impracticable due to the sheer volumes of data processing and the operator time needed to apply constant manual updates.
