Communicate road information to citizens
communicate road information to SatNavs and Phones in order to warn about potential hazards on the road ahead
I reckon that the simplest solution is the following : - gather real-time data from roads, such as average speed of vehicles, presence of traffic jams, roadworks or slow moving vehicles such as tractors. - crunch that data and then send the most appropriate information to a driver's satnav device ( it could also be a phone ). This information could be a recommended speed or potential danger ahead.
People usually make mistakes on the road because they go too fast and don't anticipate anything that is ahead.
