Pavement Image Processing Using Neural Networks
This paper discusses the potential for employing neural network models in the pavement image interpretation and classification stage of an automated pavement condition evaluation system....
Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....
Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...
Riverbank Renewal
In Providence, project teams from the public and private sector worked side-by-side, rerouting two rivers and constructing a new corporate headquarters. What made the task more challenging...
Dynamic Load Computation for Flexible Guideways Under Moving Vehicles Within a Multibody Approach
This paper addresses the problem of the dynamic interaction of vehicles with their supporting guideway. Because of topographical and environmental reasons, modern railways and magnetically...
Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...
Research on Structural System Reliability of Cable-Stayed P.C. Railway Bridge Across Hong-Shui River
This paper analyses the structural system reliability of cable-stayed bridge by using the modified all failure modes. The concept of the structural subsystem is used to help the selection...
A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...
Next Stop: The Los Angeles Metro Rail
The Los Angeles Metro Rail is a $6.5 billion light and heavy rail system, which may be entirely completed by the year 2000. A 22 mi segment of the 150 mi light rail system, connecting...
Do Current Practices in Continuing Education Fulfill the Ethical Needs of the Profession and Society?
As part of the Code of Ethics of ASCE, it is the responsibility of the engineer to fulfill both the ethical needs of the profession as well as those of society. He or she can accomplish...
IDA: A Prototype CAI System in Military Transportation
To reduce the cost and time associated with on-site training while retaining the advantage of a conventional one-to-one learning environment, a computer-aided-instruction (CAI) system...
Application of Interactive Videodisc for Work Zone Traffic Control Training
This paper describes the development of the Interactive Videodisc Training (IVT) system and a training course on work zone traffic control. The IVT system uses a microcomputer-controlled...
California DOT CADD
Starting in 1983 the California Department of Transportation (Caltrans) embarked on a project to incorporate current computer technology into the project development process. Today the...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...
The Magnetically Levitated Transport System TRANSRAPID?Characteristics and Aspects of Application
After a development of less than two decades the magnetic levitation TRANSRAPID is virtually ready for revenue service since 1985. The service has been continuously tested since 1985 on...
Public/Private Partnership for Development of the South Brunswick Station
Because of projections for continued residential and commercial growth and a large gap between stations, NJ TRANSIT decided to construct a new station in the Township of South Brunswick....
