Chapter One: INTRODUCTION AND SCOPE
3/17
Advantages of the System
Reduce the truck traffic
Improve safety
Enhance Efficiency
Improve Air quality
Help Private shippers (FedEx, UPS, U.S. postal service )
Reduce adverse environmental impacts such as emissions and noise
The proposed UFT line:
• Transports standard air crates • One end of the line is the airport
Delta/United cargo terminal• The other end is a warehouse off the
secured airport area
Chapter Two: Identifying Terminal Points
