This report describes the results of an effort to implement and analyze the performance a vehicle control system using control state information obtained from a carrier phase Differential Global Positioning System (DGPS) aided Inertial Navigation System (INS). Keywords: Vehicle Positioning...

This paper reports on the first phase of the location technology evaluation for probe vehicles. Two technologies were evaluated, Global Positioning Systems (GPS) and the cellular phone tracking technology developed by US Wireless. Although GPS has shown great potential for vehicle probes, much...

This document focuses on a Field Operational Test (FOT) to develop an integrated information system for transit and traffic management and for traveler information that relies on Global Positioning System (GPS) equipped buses as probe vehicles. The document provides the evaluation plan for the...

This report describes a simulation model developed to evaluate the impact of using Intelligent Transportation Systems (ITS), such as Global Positioning Systems (GPS) for bus tracking, on controlling buses in wide-area transit networks. Control strategies with ITS will be compared against those...

This paper is a compilation of three reports written over the 1993-96 period in the development and testing of a cadastral surveying and mapping methodology to support land registration. The sections cover (1) fieldwork to evaluate options for cadastral surveying and mapping in Albania, (2) the...

This report documents the institutional issues that have faced the Orange County probe project, a multi-agency project designed to equip a fleet of buses with Global Positioning System (GPS) based tracking equipment and to use tracking data for multiple purposes. The usefulness of the data...

Defense R&D is usually considered as an economic burden, implying an eviction effect on civilian R&D and perverting the national systems of innovation. If arms production benefits nowadays from advanced civilian R&D, the flow of technology was not always in the same direction–especially in the...

Information and communication technologies (ICT) for health or eHealth solutions hold great potential for generating systemic efficiencies by strengthening five critical pillars of a health system: human resources for health, supply chain management, health care financing, governance and service...
