Automatic vehicle location system implementation
Proceedings of Position, Location and Navigation Symposium - PLANS '96, 2002Since August, 1994 the Phoenix Fire Department's new computer-aided dispatch system has been making dispatch recommendations based on current unit locations. This has been made possible by tightly integrating an automatic vehicle location (AVL) system with the dispatch system.

Fleet management with automatic vehicle location
36th IEEE Vehicular Technology Conference, 1986A dispatcher can improve a fleet's productivity by knowing where each vehicle in the fleet is located. This productivity gain is independent of whether reduced fleet costs, increased tonnage capacity, safe delivery of secure cargo or less down time due to distracted drivers is management's goal.

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.

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

Multiobjective Model for Locating Automatic Vehicle Identification Readers
Transportation Research Record: Journal of the Transportation Research Board, 2004The problem of locating automatic vehicle identification (AVI) readers on a transportation network is one worth considering. AVI readers are strategically located to catch a maximum number of trips and cover a maximum number of origin-destination (O-D) pairs using a minimum number of AVI readers.

Time and frequency applications to automatic vehicle location
Proceedings of the IEEE, 1972A newly emerging field of fleet vehicle command and control in the urban environment is discussed. The urban environment and economic considerations present a major challenge to the development of a location system which is of major interest to the time frequency community.

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

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 ...
