During roadworks on the busy Rembrandtlaan in Voorburg, a full road closure was not an option. The challenge lay in technically planning and executing a temporary traffic situation in which traffic was guided past the worksite in phases. This project centred on the technical realisation of a traffic control installation (VRI) that accounted for flow timings, safety margins and local traffic intensity.
To arrive at a working system, we first measured traffic intensity on location and captured drone footage to get an accurate overview of the situation. Based on this data, I calculated the required intervals for the traffic lights.
A key factor was determining the exact travel time between the traffic lights and adding a safe margin, ensuring vehicles would never meet in the middle of the narrowed section. We applied the official guidelines for temporary traffic measures (TVM) throughout.
The centrepiece of the delivery was a large scale model (approx. 160x40 cm) representing the Rembrandtlaan to scale. I technically drafted the complete road markings and applied them to the model by hand to create an accurate representation. The simulation was made interactive using an Arduino setup.
I produced the traffic lights using the laser cutter from wood, working from an existing technical drawing. We then soldered the lights and connected them to a breadboard integrated into the model. By programming the Arduino with our calculated intervals, we were able to physically demonstrate the operation and safety of the proposed traffic situation.
