stakeholders requires the underst<strong>and</strong>ing of each stakeholder s needs for the surface operations. A methodology for collecting<br />

<strong>and</strong> expressing these needs has been discussed. Designing a common communication infrastructure also requires the proper<br />

integration of various communications <strong>and</strong> networking technologies. A reference model of an integrated airport surface<br />

communication systems has been proposed to meet the needs of all stakeholders.<br />

Strategies for Reducing Driver Distraction from In-Vehicle Telematics Devices: A Discussion Document<br />

Apr. 2003; 34 pp.; In English<br />

In-Vehicle Telematics refers to devices incorporating wireless communications technologies in order to provide<br />

information services, vehicle automation <strong>and</strong> other functions. Transport Canada is concerned that in-vehicle telematics devices<br />

are a threat to road safety because they increase driver distraction <strong>and</strong> cause an increase in distraction-related crashes. This<br />

concern is based on a substantial <strong>and</strong> mounting body of evidence indicating that using these devices impairs driving<br />

performance.<br />

This paper presents a control scheme for a micro-stepped two-phase linear stepping motor drive using a three-phase<br />

voltage source inverter. The purpose of this scheme is for cost reduction, since all the control loops are executed digitally <strong>and</strong><br />

a st<strong>and</strong>ard three-phase voltage source inverter is used. A space vector PWM is presented for the control of two-phase motors.<br />
