"fin"ally?

A new router could fix the problem if it happens to choose a different channel than the old router and one that is not so heavily used by neighbours. Personally, I use an app on my Android (WiFi Analyzer) that tells me the best channel to put my router on to avoid neighbours' channels.

The need to monitor traffic info in real time is demonstrated by the fact that it is already done here in UK. The data captured is non-personal and relates to the cell location of the mobile (i.e. it is detected as on a Motorway (freeway) or other major road and the speed at which the mobile is travelling. The results of the analysis basically shows that mobile cellular phones on a major road that are travelling slowly or not at all indicates a traffic jam. This is called "floating car data". The results (i.e. knowing where the traffic jams are) is then fed to motorists over a number of media so that they can replan their route to avoid the jam. Media incluse radio (as you say) but more importantly is also fed to real-time navigation devices already fitted to many cars, or available as after-market add-ons (e.g. TomTom Go). The important thing is that this can be done without the cost of installation and maintenance of road sensors/traffic cameras.
