An Offline Framework for the Diagnosis of Time Reliability by Automatic Vehicle Location Data
IEEE Transactions on Intelligent Transportation Systems, 2017Time reliability problems are unavoidable, owing to the stochastic context in which bus services are operated. Therefore, characterizing their reliability and understanding possible sources of unreliability provides an opportunity to keep buses on schedule and/or maintain planned headways.

Regularity diagnosis by Automatic Vehicle Location raw data
Public Transport, 2012Bus regularity is a crucial factor for high frequency public transport systems, because it represents a relevant measure of quality of service for both users and transit agencies. Low regularities for users are associated with bunching phenomena or large gaps between buses, which result in low attractiveness of the service for transit agencies ...

Integrated automatic vehicle location systems
IEEE Aerospace and Electronic Systems Magazine, 1997The state-of-the-art transportation management system integrates automatic vehicle location, in-vehicle systems, customer information networks, and management information systems. As advanced technologies are integrated into transportation systems, the transit system becomes more efficient and reliable, which, in turn, makes it more attractive to users.

Programmable GPS Receiver for Automatic Vehicle Location
2006 IEEE International Conference on Automation, Quality and Testing, Robotics, 2006Automatic Vehicle Location (AVL) systems are a very usefull tool for vehicle fleet management. The transport operators have the possibility to be informed about their vehicles locations. A dispatcher achieves voice and data communications with mobile terminals, installed on vehicles. The mobile terminals send their position data to the dispatcher.

Evaluating dispatching consequences of automatic vehicle location in emergency services
Computers & Operations Research, 1978Abstract Automatic vehicle location (AVL) systems present to the dispatcher of emergency response units (e.g., police cars, ambulances) the estimated real time locations of units within his service area. Building on a recently developed hypercube queuing model, this paper presents a Markov process model for computing the operating characteristics of ...
