Monitoring traffic lights

Sensors in the traffic lights themselves and loops in the road calculate various information about the traffic lights, such as waiting time and how many vehicles run red lights. This is displayed in a dashboard.

Goal and impact

The purpose of this algorithm is to test and control the traffic schemes.

Considerations

These algorithms provide insight into traffic and traffic flows at a traffic light. The disadvantages of this algorithm is that it can sometimes give false reports. A failure of a loop, for example, can give an unjustified report of a redditor.

Human intervention

The algorithm collects the data and presents it in a dashboard. This data is used by municipal employees to review and monitor traffic policies and settings.

Risk management

The municipality complies with applicable legislation regarding disclosure of data to third parties and data retention.

Legal basis

The Road Traffic Act 1994 (WVW) is the basis for all traffic rules. The basic principle here is the smoothness and flow of traffic and that no one should cause a nuisance or danger on the road.

Operations

Data

Sensors of traffic lights, loops in the road

Technical design

Traffic lights collect data and through the algorithm this is translated into information about the traffic light. This data appears in a dashboard.

For more information on the information collected, see also algorithms Intelligent Traffic Control Installation (iVRI) at traffic lights and traffic light installations.

External provider

The supplier is Technolution, the application used is MobiMaestro STATS.

Similar algorithm descriptions

  • Whereas ordinary traffic lights register by detection loops (sensors in the road) that traffic is passing over, 'smart' traffic lights additionally register via apps what kind and how much traffic is coming. This allows traffic lights to see traffic "arriving" earlier and thus determine how long the traffic light is on green.

  • Intelligent traffic lights can detect various mobilities with sensing loops and push buttons and connect to in-car systems and navigation apps. To see traffic "coming" at an earlier stage and regulate it even smarter.
