Characteristics Analysis of Bus Stop Failure Using Automatic Vehicle Location Data

Automatic Vehicle Location in Public Bus Transportation System

For a number of years vehicle fleet tracking systems are in use in companies operating large number of vehicles in the field. Proliferation of cheap and compact GPS receivers had the effect that Automatic Vehicle Location (AVL) systems today almost exclusively use satellite based locating systems. This paper presents characteristics of realized city bus transit traffic in the city of Niš. Since...

Efficient location by using data envelopment analysis

So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...

Automatic Vehicle Location Systems

In this article, a single application is suggested to determine the position of vehicles using Geographical Information Systems (GIS) and Geographical Position Systems (GPS). The part of the article material included mapping three dimensional coordinates to two dimensional coordinates using UTM or LAMBERT geographical methods, and the algorithm of conversion of GPS information into GIS maps is ...

Failure Mode and Effects Analysis Using Data Envelopment Analysis

Validation of Automatic Vehicle Location Data in Public Transport Systems

Performance metrics for public transport systems can be calculated from automatic vehicle location (AVL) data but data collection subsystems can introduce errors into the data which would invalidate these calculations, giving rise to misleading conclusions. In this paper we present a range of methods for visualising and validating AVL data before performance metrics are computed. We illustrate ...
