Automatic vehicle location (AVL) for transit operation
2000 10th Mediterranean Electrotechnical Conference. Information Technology and Electrotechnology for the Mediterranean Countries. Proceedings. MeleCon 2000 (Cat. No.00CH37099), 2005The purpose of the AVL system is to monitor the location of buses. Knowing the location of a bus enables the operator to manage the bus fleet more efficiently and to provide their customers with up to the minute information on bus arrivals and departures.

AVLN 2000 automatic vehicle location and navigation system
Conference Record of papers presented at the First Vehicle Navigation and Information Systems Conference (VNIS '89), 2003This prototype system is being tested at the University. The positioning component consists of a GPS Trimble TANS (Trimble Advanced Navigation System) receiver, a pair of Nu-Metrics odometers, and a map-matching module, all integrated by a seven-parameter state vector Kalman filter to yield continuous positioning of the vehicle.

Automatic vehicle location Dallas test results
27th IEEE Vehicular Technology Conference, 1977The FCC allocation of a wide band channel at 900 MHz for an Automatic Vehicle Monitoring (AVM) service presented the opportunity to Hazeltine to develop a vehicle locating system that can support 5,000 vehicles with high location accuracy information and rapid two-way data message transmissions. The system is configured to have variable up-date rate of

Multipath and ducting tolerant location techniques for automatic vehicle location systems
26th IEEE Vehicular Technology Conference, 1976This paper discusses various methods of improving the accuracy of a linear least squares solution algorithm which is commonly used in Time Difference of Arrival (TDOA), hyperbolic location systems. Topics considered include methods of generating a useful weighting matrix and a residue examination scheme as the basis for rejecting data contaminated by ...

Transit User Perceptions of the Benefits of Automatic Vehicle Location
Transportation Research Record: Journal of the Transportation Research Board, 2002An attitudinal survey on transit riders’ perception of the importance transit users place on features of an automatic vehicle location (AVL) system is reported. Onboard surveys and on-time field checks were conducted in the cities of Manitowoc and Racine, Wisconsin, to determine how users in those cities perceive their transit systems and how well each
