Intelligent Transportation Systems

Visualizing Advanced Embedded Video and Vision System, In-Cab Multifunction Display SystemsIntelligent Transportation Systems (ITS) can be defined as the application of advanced information and communications technology to surface transportation in order to achieve enhanced safety and mobility while reducing the environmental impact of transportation. 

Transportation

Modes of transport include air, rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles and operations. Transport infrastructure consists of the fixed installations including roads, railways, airways, waterways, canals and pipelines and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and seaports. Vehicles traveling on these networks may include automobiles, buses, trains, trucks, people, helicopters and aircraft. Passenger transport may be public, where operators provide scheduled services, or private.

Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) Communications

Functional Safety Standards For Road Vehicle, Railway Applications, Tractors And Machinery, Earth-Moving MachineryVehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) Communications are an emerging type of networks in which vehicles and roadside units are the communicating nodes; providing each other with information, such as safety warnings and traffic information.

The US Department of Transportation (DOT) is soliciting (FOA DTFH61-13-RA-00004) applications for cooperative pre-competitive projects designed to enable the successful deployment of vehicle-to-infrastructure (V2I) crash avoidance and driver information applications in passenger vehicles. Projects will last 60 months; estimated total program funding is up to $45 million.

V2I applications are those applications which vehicle-based sensors and vehicle-to-vehicle (V2V) communications are not considered adequate for development of information, alerts, or warnings for drivers. These V2I applications require additional information from the infrastructure to be enabled. These applications, however, are vehicle-based, in that they are programs resident in the on-board equipment of the vehicle.

The on-board systems use information from vehicle-based sensors, V2V communications, and V2I communications to determine if information, alerts, or warnings should be provided to the driver. Learn more>

Applications

Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) Communication networks will provide a wide range of applications with different characteristics. The possible applications in the following categories:

  • Safety: Warnings on entering intersections, warnings on departing the highways, obstacle discovery, school zone warning, sudden halts warnings, reporting accidents, lane change warnings and other applications that provide information to the driver
  • Mobility: The development of vehicle-to-infrastructure mobility applications and associated technologies for increasing overall transportation system efficiency and improving individual mobility
  • Positioning: The performance of GPS positioning in challenging environments (e.g. urban canyons, tunnels, etc.). The existing and new technologies might be adapted to support the GPS positioning requirements of connected vehicle safety applications
  • Traffic Management: Variable speed limits, adaptable traffic lights, automated traffic, intersection control, accommodating ambulances, fire trucks, and police cars, driver assistance systems, pricing and payments.
  • Driver Assistance Systems: Parking a vehicle, cruise control, lane keeping assistance, and road sign recognition
  • Policing And Enforcement: Surveillance, speed limit warnings, restricted entries and pull-over commands
  • Pricing And Payments: Toll collecting and parking payments
  • Travel-Related Information: Maps, business locations, car services and gas stations
  • General Information Services: Web surfing, file downloads email and gaming


In-Vehicle Display and Embedded Technologies

Intelligent Embedded Video and Vision Systems Engineering and ServicesRecent advances In-Vehicle Electronics and Displays have led to a move toward fewer, more capable computer processors on a vehicle. A typical vehicle in the early 2000s would have between 20 and 100 individual networked microcontroller/programmable logic controller modules with non-real-time operating systems.

The current trend is toward fewer, more costly microprocessor modules with hardware memory management and Real-Time Operating Systems. The New Embedded System with Advanced Embedded Video & Vision platforms allow for more sophisticated software applications to be implemented, including model-based process control, artificial intelligence, and ubiquitous computing.
