Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: Comparable Systems Analysis


In-Vehicle Motorists Services Information Systems (IMSIS)


IMSIS provides:

  1. Broadcast information on services/attractions.
  2. Access to a services/attractions directory.
  3. Destination coordination.
  4. Message transfer capability.

Broadcast Services/Attractions Information

Broadcast services/attractions information provides travelers with information that might otherwise be found on roadside signs. It may be very similar to the services and attractions information typically given on signs; but it will be displayed inside the moving vehicle.

Services/Attractions Directory

This capability provides information about motels; hotels; automobile fuel/repair; and emergency medical, entertainment, and recreational services. Using this capability, the driver can access relevant information concerning businesses or attractions.

Destination Coordination

The destination coordination function enables the driver to communicate and make arrangements for the final destination. This may include restaurant and hotel reservations.

Message Transfer

The message transfer capability allows drivers to communicate with others. Currently, this function is implemented by cellular telephones and CB radios. In the future, ATIS systems may improve upon this technology by automatically generating preset messages at the touch of a button and by receiving messages for future use. Message transfer might involve both text and voice messages.
