20 Nov 1969TL;DR: In this article, a vehicle guidance and control system for providing information concerning the speed and direction of movement of a vehicle along a predetermined path on a roadway is presented, where the path is defined by a plurality of spaced, permanently magnetized elements located along the roadway.
Abstract: A vehicle guidance and control system for providing information concerning the speed and direction of movement of a vehicle along a predetermined path on a roadway. The path is defined by a plurality of spaced, permanently magnetized elements located along the roadway. Vehicle mounted sensors respond to the magnetic fields of the elements and produce electrical signals representing the speed and direction of movement of the vehicle with respect to the path. In one embodiment, the electrical signals are employed as control signals in a closed loop electromechanical guidance system for the vehicle. By varying the pattern of magnetic polarization of the elements, binary information can be transferred from the roadway to the vehicle. With suitable data processing equipment in the vehicle, traffic information, such as, speed limits, directions, accident information, exit directions and the like can be visually presented to the vehicle operator.

TL;DR: The system has been designed to help the visually impaired by responding intelligently to various situations that can occur in unrestricted natural outdoor environments when walking and finding the destinations by using the main functions of people detection, text recognition, face recognition.
Abstract: In this paper, we present a walking guidance system for the visually impaired pedestrians. The system has been designed to help the visually impaired by responding intelligently to various situations that can occur in unrestricted natural outdoor environments when walking and finding the destinations. It involves the main functions of people detection, text recognition, face recognition. In addition, added sophisticated functions of walking path guidance using Differential Global Positioning System, obstacle detection using a stereo camera and voice user, interface are included. In order to operate all functions concurrently, we develop approaches in real situations and integrate them. Finally, we experiment on a prototype system under natural environments in order to verify our approaches. The results show that our approaches are applicable to real situations.

TL;DR: An overview of route guidance systems is provided, a portable device that provides advice to the driver on the route to take from his current position to this destination based on real-time traffic information is described and the TravElGuide concept is compared against routes guidance systems in operation or under development elsewhere.
Abstract: The Ministry of Transportation, Ontario, is actively pursuing the assessment and possible development of TravElGuide, a route guidance system that will offer most of the benefits of more advanced systems but at significantly lower cost. The present concept includes a portable device that provides advice to the driver on the route to take from his current position to this destination based on real-time traffic information. Transit users can find out about the expected arrival time of buses at their stop. The system does not include an on-board vehicle location or navigation capability but rather relies on the driver to act as the navigator. This significantly reduces cost without significantly sacrificing functionality. This paper provides a brief overview of route guidance systems, describes the TravElGuide concept and compares it against route guidance systems in operation or under development elsewhere.
