Image Analysis of Clay Microstructure
The paper summarises new methods which have been developed to analyse oriented textures in electron micrographs of clay soils, complementary methods using polarising microscopy, and an...

Machine Vision Based Traffic-Adjusted Intersection Signal Control
This paper describes some of the available machine vision systems and how they can be effectively used for traffic control at an intersection. A set of rules have been defined which make...

Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...

Survey of Image Processing Applications in Civil Engineering
A number of imaging products have been developed for civil engineering applications. This paper attempts to survey various image processing applications in civil engineering up to date....

Computer Vision Techniques for Comparing Laser Doppler Velocimeter Scans of a Vibrating Plate to Analytical Plate Modes
Computer vision procedures were applied to velocity images of a vibrating square steel plate. A scanning laser Doppler velocimeter (LDV) measured the images of low frequency resonant operating...

Application of Digital Images and Processing for As-Built Construction Drawings
The production of as-built drawings is a labor intensive activity that often provides the facility owner with inaccurate or incomplete final drawings. This paper briefly reviews work accomplished...

A Constructability Lessons Learned System for Infrastructure Rehabilitation Using Digital Image Processing
Due to the complex nature of many infrastructure rehabilitation projects, there is a strong need for design/construction integration, and more specifically, the application of strong constructability...

Optimal Region Aggregation with Shape Considerations in Spatial Optimization
The region aggregation (land acquisition) problem is discussed within the context of a regular grid matrix having representative cell indices or attribute values. Several optimization...

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...

North Ramp Pavement Evaluation/Rehabilitation?Houston Intercontinental Airport
The North Ramp at Houston's Intercontinental Airport is approximately 23 years old and serves Terminals A and B and also serves as a primary taxiway. Prior to having the new international...

An Introduction to APM Systems and Applications
An Automated People Mover (APM) is an advanced transportation system in which automated driveless vehicles operate on fixed guideways in exclusive rights-of-way. These differ from other...

Reflections on the New Systems Study Project
1993 marks the 25th anniversary of the New Systems Study Project. This project produced a report from President Johnson to the Congress entitled....

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...

The Development of Public Transport Systems for Urban Areas and the Relation with People Movers
The development of new public transport concepts for urban areas has to be related to problems in this field. Therefore on the one hand in a systematic way an inventory is made of the...

A Vision for 21st Century Guided Transit
The design characteristics for 21st century fixed guideway transit are discussed. A system concept responsive to passengers' needs is envisioned. The concept ignores traditional boundaries...

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...
