Urban mobility faces challenges such as high numbers of traffic fatalities including of children, and vehicles searching for parking taking up city traffic. Cooperative intelligent transport systems and services could help cities address these issues through ideas like comParking, which provides parking availability and guidance; comBus&Train, which provides public transit information and flexible scheduling; and comTraffic, which enables cooperative traffic control and vehicle priority to improve traffic flow. Partnerships are needed to realize the vision of a mobile city with cooperative mobility systems and services.
