Cable Propelled People-Movers?An Idea Whose Time Has Come Again
Cable-propelled transportation systems have been in use throughout the world for more than a century. Today, a completely automated cable-propelled transit system has been developed through...

The H-Bahn, a Fully Automatic People Mover System
The H-Bahn suspended cabin system is the contribution of the Siemens - DUEWAG joint development venture towards solving the problem of economical public transportation. This track-bound...

Unique Features of Automated People Mover Systems
This paper identifies the characteristics and unique features of the automated transit system presently being installed in the central business district of Detroit, Michigan. This system...

Human Interface Design of an APM Control Center
The control center of an Automated People Mover (APM) system is a man-machine system. Both software and hardware aspects of the design of the monitor room that directly affect ease of...

Detroit's DPM Maintenance and Control Facility
The Maintenance and Control Facility (MCF), a single building complex for the Detroit Downtown People Mover (DPM) system, incorporates the people mover system's transit vehicle...

Alternative Procedures for Investigating Failures
Failures of engineered structures continue to occur. This is despite rapid advances in engineering theory, new, more sophisticated methods of analysis, and streamlined techniques for preparing...

Failure Information Needs in Civil Engineering
If we are to learn from failures of engineered facilities, failure information must be in a useful form, and it must reach those who can effect improved practice. This paper discusses,...

Ensuring Quality Construction
This paper describes the US Army Corps of Engineers' efforts at procuring quality construction: 1) a three-phase approach (preparatory, initial, follow-up) was developed to...

Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...

Avoiding Disputes: The Construction Manager's View
Avoiding and minimizing contract disputes, from the construction manager's (CM) point of view, begins during the preliminary planning and design stages and continues throughout...

Construction Inspection?The Last Line of Defense
Construction inspection, or a quality assurance program, is typically the last line of defense in relation to claims for the constructed project. The quality assurance team should be a...
