Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...
Evaluation of a Proprietary Tape Coating Alternative for the 157 Mile Ivie Pipeline
A two part evaluation of alternative protective coating systems for the 157 mile Ivie pipeline was made. In Part I, an evaluation was made on the suitability of a proprietary tape coating...
The Rokko Island Line of the Kobe New Transit System
Because Rokko Island was planned to be a mini-city with all the typical urban functions, it was essential to provide a means of transportation connecting it with the existing urban center...
Transportation Management Systems?The Key to Efficiency
Federal, State, and local governments are under increasing pressure to balance their budgets and cut costs while at the same time respond to public demands for quality services. The current...
Commercial Aviation Maintenance
The Federal Aviation Administration (FAA) issues regulations and advisories for commercial airlines which establish the basis of the aviation maintenance and inspection programs. Commercial...
Congestion Pricing with Tolls and Subsidies
Though economists have promoted congestion pricing for many years it has, in general, met with public opposition. It is usually argued that congestion pricing is unfair, discriminatory,...
Coordination of ISTEA?1991 Management Systems
Following the successful development and implementation of pavement management concepts, the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains the provision that...
Design Implications for Concrete Pavements from LTPP Analyses
Among the original objectives of the Long-Term Pavement Performance (LTPP) study of the Strategic Highway Research Program (SHRP) were the evaluation of existing design methods for pavements,...
Changes to the AASHTO Guide for Design of Pavement Structures
At this juncture of the SHRP-LTPP program, it is appropriate to discuss the potential impacts that SHRP-LTPP results could have on the future AASHTO Guides for the Design of Pavement Structures....
Real Time Public Transport Information Systems in
The objective of this work is to demonstrate the use of Advanced Transport Telematics (ATT) in a multimodal transport environment. The focus of the work is on the integration of ATT methods...
DART'S ASAP EIS
An environmental impact statement that takes several years to complete can demoralize the staffers behind a transportation project and reduce public support for the effort. In a hurry...
Removal, Replacement and Rehabilitation of Concrete Slabs
The project involved existing one-way slabs experiencing severe corrosion damage. The slabs were removed and replaced while salvaging the concrete beams and frame components. Significant...
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....
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...
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...
