Intelligent Transportation Systems
An Intelligent Transportation System is an advanced application which aims to provide innovative services relating to different modes of transport and traffic management and enable users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks.
Traffic Management Centers
Traffic Management Centers (TMCs) serve as the mission control for an urban area’s major street and highway network. This one location monitors traffic signals, intersections, and roads and proactively deploys traffic management strategies to reduce congestion and coordinate state and local authorities during special events and emergencies.
Vehicular Communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure.
Architecture of Intelligent Transportation Systems
Electronic Toll Collection
Electronic Toll Collection is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card.
Public Bicycle Sharing System
Public Bicycle Sharing System is a service in which bicycles are made available for shared use to individuals on a short term basis for a price or free.
Many bike share systems allow people to borrow a bike from a "dock" and return it at another dock belonging to the same system.
Docks are special bike racks that lock the bike, and only release it by computer control. The user enters payment information, and the computer unlocks a bike. The user returns the bike by placing it in the dock, which locks it in place.
