Innovations in the Development and Expansion of Intermodal Facilities
The intermodal industry is a dynamic one, with a long history which has undergone profound change since the introduction of containerization only 30 years ago. Today, change continues...
Trip Rates Adjustments for Impact Assessment and Congestion Management
Evidence that all urban trips are not equal and that trip rates need to be adjusted to reflect the differential contribution of trips to traffic loads and congestion is presented. Adjustments...
BMS Modelling of Bridge Stock Performance
A computer-based Bridge Management System, BMS, was designed in Finland by the Finnish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Computer-Aided Liability
Civil engineers are using computers more than ever to help them streamline analysis and design, boost productivity and cut costs. Often they rely on mass-marketed software such as Autodesk...
The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...
Digital Image Processing: Experiences in the Gulf War
During the 1990-91 conflict in Southwest Asia between Iraq and coalition forces operating with US Armed Forces, the utility of products developed from digital imagery and digital terrain...
Digital-Image-Based Computer Modelling of Cement-Based Materials
Understanding the relationships among materials, processing, microstructure, and properties is critical in improving material design. This paper outlines an approach for furthering this...
Video Modeling: A New Paradigm for Reproducing Complex Engineering Artifacts on Computer
This paper introduces a novel approach for automatically creating accurate computer models of existing, physical artifacts. Based on the projected silhouettes of the object, when viewed...
A New Three-Dimensional Modeling Technique for Studying Porous Media
A new three-dimensional technique for modeling the micro-structure of porous media is proposed. On the basis of measurements of characteristics made using thin sections of porous media...
Image Analysis for Interparticle Contact Modeling
Two dimensional photoelastic elements (disks or ellipses) are used as models for studying granular material behavior. The required observations include accurate continuous measurements...
Image Enhancement: Application to Geotomography
Image enhancement complements geotomographic reconstruction in the rendering of better images. In this paper, available image enhancement techniques are reviewed. Emphasis is given to...
Displacements in the Soil Near a Tunnel Face Using Centrifuge Tests and Image Processing
Image processing is applied to measurements of the soil for a tunnel model in centrifuge. For this aim a specifical device has been developed on the LCPC centrifuge (Nantes, France) and...
Mechanistic Design Models of Loading and Curling in Concrete Pavements
Determination of the critical bending stress at the edge of a concrete pavement due to individual and combination effects of wheel loading and thermal curling is very crucial to any mechanistic...
Finite Element Analysis of Slabs-on-Grade Using Higher Order Subgrade Soil Models
Incorporation of the two-parameter, Kerr and Zhemochkin-Sinitsyn-Shtaerman subgrade models into finite element code ILLI-SLAB is described. The two conventional idealizations, namely the...
