Mathematical Modeling of Airport Pavements
Theories for analyzing rigid pavements are presented. The emphasis is on the choice of the proper models for the pavement and for the subgrade, and on the correct mathematical formulation...

Unified Constitutive Model for Airport Pavements
A unified constitutive model that allows for significant behavioral characteristics of materials and interfaces in airport pavement is implemented in a nonlinear finite element procedure....

Reliability-Based Analysis and Design of Flexible Airfield Pavements
This paper illustrates, a new reliability-based procedure to analyze existing pavements and design new pavements that is being developed by the U.S. Air Force. The procedure uses a rigorous...

Pavement Design Considerations for Heavy Aircraft Loading at BAA Airports
BAA operates seven airports in the United Kingdom. Two of them, Heathrow and Gatwick, handled 61 million passengers in 1991 with 543,000 air transport movements, 25% by wide-bodied aircraft....

Durability of Asphalt Mixture
Five asphalts were used in a laboratory testing program to establish a relationship between mixture properties and the binder properties. These five asphalts were used to make Florida...

Ft. Campbell Airfield Emergency Reconstruction
The air deployment from Fort Campbell, Kentucky to Saudi Arabia in support of Operation Desert Storm in the summer and fall of 1990 involved several hundred C5 and C141 aircraft loaded...

Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...

Measurement and Analysis of Airside Pavement Roughness at the Dallas/Fort Worth International Airport
In May 1990, Dallas/Fort Worth International Airport management contracted with Harding Lawson Associates to implement a pavement management system for that airport. In this implementation,...

A Marketing Analysis of an Old Concept: the Horizontal Elevator-Monorail
The objective of this research is to define an efficient and cost effective concept for an Automated People Mover (APM) System. Current solutions are relatively expensive to install, have...

Active Guideway Systems
Many automated people movers which have been developed or studied in France or in other countries belong to the category of active guideway systems. This paper describes characteristics...

Comparative Analysis of Different Systems for a New Rail Line in Copenhagen, Denmark
A new Mass Transit System is to be built in Copenhagen, Denmark. The Copenhagen Public Bus Company, HT, and the Danish State Railways, DSB, have each carried out feasibility studies. Conventional...

Technological Innovations: Opportunities to Reduce Costs
This paper presents a comparative study of an automatic dedicated single track people mover and an automatic dedicated double track people mover. The study examined both `system' and infrastructure...

Integrating Waiting Time in the Design of a Transportation System for Short to Intermediate Distances
This paper addresses passenger perceptions of short to medium distance public transportation systems. The concept of the weighted total transportation time (WTTT) is introduced, integrating...

A Public Transport System Based on Light Electric Cars
This paper presents the concept under development in France of a novel transportation system based on fleet of small public cars under supervision from a central computer. These public...

Concept of a Polycentric Metropolitan Area with Automated People-Movers
The general equation of mobility is used to understand the development of urban systems. Using iterative methods it is shown that the town planning criterion used currently gives rise...

TRANS-GRAPH?Advanced Software for Simulation Modeling of Automated People Mover Systems
TRANS-GRAPH is an integrated system of proprietary computer software designed specifically to enable comprehensive system analysis of automated people movers. The TRANS-GRAPH software...

Jacksonville's ASE Crosses the River
After over three years of operation, the Jacksonville (Florida) Automated Skyway Express (Skyway) downtown people mover system is expanding. The Jacksonville Transportation Authority (JTA),...

The Von Roll Monorail at Merry Hill, U.K.
In June 1991 a Von Roll monorail commenced operations at the privately developed Merry Hill Shopping Centre in the U.K. The paper describes the application of the Von Roll monorail to...

Providing People-Mover Access for the Getty Center
An Otis People-Mover System was selected by The Getty Trust to transport visitors to The New Getty Center Museum for the Arts from an entry parking area up a steep hillside to the museum...

The New U.S. Senate Subway System
It was recognized in 1909, when the first Senate Subway System was installed, that a rapid means of securely transporting Senators from their remote offices to the Capitol Building was...
