The rise of ride-sharing services like Uber and Lyft – essentially taxis booked at the click of a smartphone button – and apps like Waze, which uses real-time traffic data to find the quickest routes for drivers, is dramatically changing how people get around, and affecting the very way in which traffic moves through a city.
 Communication between riders and drivers, between different vehicles and between cars and infrastructure is bringing transportation into a new era, according to Allan Clelland, senior vice president at Iteris, a company developing new transportation technology.
