The humble traffic signal is gaining some new responsibilities.
Excellent story and it is very exciting the direction that traffic management is taking. There is of course some optimism when it comes to V2V communications. There are not currently any international standards and in fact many of the systems currently going into new cars are only capable of communicating with other cars of the same brand.
When looking at the effect of these V2V systems, there is a critical mass required in order to have any effect and of course most people don’t regularly buy new cars. Having said that, research by TomTom in the UK a few years ago suggested that if 5% of cars on a highway positively changed their behavior due to real time information, it could benefit as much as 15% of traffic, even if the latter don’t have car navigation with real time traffic in them.
