Traffic light control systems: an overview
00.002
Creating a traffic light control system starts with a detailed analysis of the traffic situation. We collect data such as traffic intensities, queue lengths, journey times, and key policy objectives to determine which movements have priority, especially during busy times. We also look critically at the layout of the intersection, such as lanes and facilities for cyclists, pedestrians, and public transport, to create an appropriate design.
In the next step, we develop the light control, always assuming a completely conflict-free design: safety is our highest priority. We calculate cycle times and green time distribution and adjust the design if necessary, for example with a separate turn lane or bus lane. We repeat this process until traffic flow and waiting times for all road users are in line with the set priorities. The trade-off between safety and traffic flow is always customised.
Finally, we add vehicle-dependent operation, which we test and optimise with microsimulations. Using intelligent detection systems, we adjust the duration of the green phase to traffic density and detect public transport and active road users. In this way, we create a traffic light regime that is both safe and efficient.
We developed the traffic light arrangements for the following locations:
TML also designs traffic light control systems through a framework contract with the Agency for Roads and Traffic. Cities and municipalities can sign up to have us draw up their control systems. For more information, contact Ruben Corthout.

We developed the traffic light arrangements for the following locations:
- The Royers lock in Antwerp (22056)
- Tremelobaan in Keerbergen (24019)
- The N715 in Houthalen-Helchteren (22048)
- The intersection between Wommelgemsteenweg and Eikenlaan in Wijnegem (22007 and 25019 (follow-up study))
- RO Nieuwpoort N34 Kustweg (22018)
- Matenstraat in Niel (24073)
- The intersection between the N32b and Krommebeekstraat in Vossemeren (19068)
- Antwerp (15106)
