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...

Densification of Asphalt Pavements by Traffic
Since asphalt pavements rut when the voids are filled with asphalt (and voids can become filled by traffic densification) the voids that develop under traffic are vital to any mix design...

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...

The Fundamental Gap in Urban Transportation
This is not a technical paper. It is perspective paper, designed to detail the failure of current urban transportation strategies and call for new thinking and action responsive to the...

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),...

Las Vegas?A Significant APM Market
Las Vegas, the gambling and entertainment center of the nation, contains the world's largest concentration of hotels and casinos, and attracts over 18 million visitors a year. APMs have...

Determining AGT Feasibility and Potential Alignments for Mission Valley
The objective of the Mission Valley Guideway Transit Study was to assess the feasibility of developing a completely elevated, fully automated guideway transit system to serve as a circulator/distributor...
