The transportation industry is going through a resurgence. Everything is increasing: traffic, congestion, the percentage of connected cars on the road – even the number of pedestrians. Transportation agencies need to respond to these changes to improve public safety and make travel easier for drivers and passerby. Fortunately, the internet of things (IoT) can play a pivotal role in Vision Zero, a multi-national road traffic safety project aiming to put a stop to fatalities and serious injuries involving road traffic.
