Belgium has intelligent traffic lights already. You can't use an app system like this without existing smart traffic light infrastructure.
This just allows for better traffic flow management by predicting influxes of traffic along long roads.
But, more importantly, it allows traffic planners to analyze popular sources/destinations on the road map. If 90% of cars turn left at a certain traffic light but only because the traffic light before it takes forever to turn green, they can tweak the scheduling to divide traffic more evenly.
The obvious downside, of course, is that this data will quickly show individuals when analyzing patterns in remote areas.
