The Netherlands has about 5,000 traffic light controllers (TLCs), of which 350 now are iTLC (intelligent traffic light controllers).
Several hundred iTLCs are in preparation to be connected to the data exchange system that is available in The Netherlands.
Connecting Intelligent Traffic Light Controllers (iTLCs)
The implementation is not going as fast as initially expected. We see that, especially in large cities, it takes more time. The reason behind this is that it is new, and everything new and being done for the first time often takes more time than expected.
In addition, the matter is complex, plus the standardisation takes time. Normally, traffic lights are depreciated over 15 years. It is foreseen that at least 1,000 more iTLCs will be added by 2023.
A smart intersection sees traffic arriving earlier. This helps to regulate the flow in more detail or to give the fire service and ambulance free rein. Alternatively, other special traffic groups can also be given priority. Think of a bus with a delay or a heavily loaded truck that can better continue driving to save fuel and reduce emissions.
Live traffic data
Traffic Live Exchange (TLEX) from Monotch, a platform for live traffic data, provides the data connection between all iTLCs and road users in the Netherlands. The realisation of TLEX arose as a collaborative project between Monotch and Swarco as part of the Partnership "Talking Traffic".
The idea of Talking Traffic is that the traffic light “talks” back: the driver sees whether the light is green or red on an in-car or mobile device. It shows you how long you have to wait depending on the traffic rules.
