Connected Vehicle Applications

Connected vehicle applications are being developed to address real-world problems. The following table depicts significant transportation challenges and identifies how the connected vehicle vision and applications are intended to address them.

Safety Problem Imagine: Image of a vehicle with green half circles indicating transmission of data.
  • 37,261 deaths/year (US)
  • 5.8 million crashes/year (US)
  • Direct economic cost of $230.6 billion
  • Leading cause of death for ages 4 to 34
  • Your vehicle can "see" vehicles you can't see
  • Your vehicle informs you of roadway conditions and hazards that you can't see
  • Your vehicle knows the speed and location of approaching vehicles
Connected vehicle safety applications are designed to increase situational awareness and reduce or eliminate crashes through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) data transmission that supports: driver advisories, driver warnings, and vehicle and/or infrastructure controls. These technologies may potentially address up to 82 percent of crash scenarios with unimpaired drivers, preventing tens of thousands of automobile crashes every year (further research will incorporate heavy vehicle crashes including buses, motor carriers, and rail).

Mobility Problem Imagine:  
  • Traffic congestion $87.2 billion annual drain on the U.S. economy...
    • 4.2 billion lost hours
    • 2.8 billion gallons of wasted fuel
  • Managing the transportation system as if you knew where every vehicle (automobiles, trucks, motor coaches, and transit vehicles) was in real time
  • Planning for growth patterns as if you could see complete traffic patterns around development
  • Planning travel as if you knew real-time options on all roads, transit, and parking along your route
Connected vehicle mobility applications provide a connected, data-rich travel environment. The network captures real-time data from equipment located on-board vehicles (automobiles, trucks, and buses) and within the infrastructure. The data are transmitted wirelessly and are used by transportation managers in a wide range of dynamic, multi-modal applications to manage the transportation system for optimum performance.

  Environment Problem Imagine:

  • 2.8 billion gallons of fuel wasted each year
  • 22% CO2 emissions from vehicles
  • Managing your system for environmental and weather events as if you knew specific information about the road and vehicle
Connected vehicle environmental applications both generate and capture environmentally relevant real-time transportation data and use this data to create actionable information to support and facilitate "green" transportation choices. They also assist system users and operators with "green" transportation alternatives or options, thus reducing the environmental impacts of each trip. For instance, informed travelers may decide to avoid congested routes, take alternate routes, public transit, or reschedule their trip — all of which can make their trip more fuel-efficient and eco-friendly. Data generated from connected vehicle systems can also provide operators with detailed, real-time information on vehicle location, speed, and other operating conditions. This information can be used to improve system operation. On-board equipment may also advise vehicle owners on how to optimize the vehicle's operation and maintenance for maximum fuel efficiency.

Connected vehicle technology and policy underpin the successful development and deployment of these applications by:

  • Providing a platform for interoperability, security, and access that is based on a logical, systems approach.
  • Distinguishing the appropriate boundaries that effectively leverage public-sector funding versus private-sector financing and market opportunities.
  • Defining minimum governance requirements that use regulatory actions only when fact-based evidence (based on field testing and evaluation) points to its effectiveness.
  • Identifying options for resolving institutional issues that enable successful deployment and sustainable market development and growth.
  • Providing a platform for effective technology and knowledge transfer.

The following are the specific connected vehicle applications research areas:

  • Safety:
       
    Vehicle to Vehicle Communications for Safety
       Vehicle to Infrastructure Communications for Safety
  • Mobility:
     
     Real-Time Data Capture and Management
       Dynamic Mobility Applications
  • Environment:
       
    Applications for the Environment: Real-Time Information Synthesis (AERIS)
       Road Weather Applications for Connected Vehicles
