Cost Savings from AVMC Systems in Trucking
The paper presents a brief overview of a methodology by which the cost savings of advanced vehicle monitoring and communication (AVMC) systems in long distance or intercity trucking can...
Magnetically levitated vehicle technology, maglev, serves as a potential solution to ever increasing transportation demands. Though interest in maglev appears to be increasing, an appropriate...
Potential Freeway Capacity Effects of Advanced Vehicle Control Systems
Intelligent Vehicle/Highway Systems (IVHS) are intended to improve the productivity (capacity) and safety of the road transportation system. The PATH program has placed a stronger emphasis...
Safety of IVHS: Methods for Determination of Accident Levels for AVCS-1 Devices
This paper discusses ways in which the safety impact of Intelligent Vehicle/Highway Systems (IVHS) devices can be estimated by interpreting existing statistics. This is needed at many...
Taming the Silicon Steed?Perceptions of Risk
This paper draws from contemporary research in the psychological literature to argue that transportation engineers and decision makers should consider the issue of perceived risk when...
Infrared Detector Developments
Modern road transport systems rely on information from sensors to operate safely and efficiently. The sensors are typically used to provide vehicle counting, occupancy, speed measurement...
The California Inductive Loop Radio Demonstration Project
There is growing interest at both the national and international level in the application of new technologies to the highway system. While many of these new technologies are revolutionary...
Assessment of IVHS Research Efforts in Japan and Future Directions
In the past twenty years, research on intelligent vehicle/highway systems (IVHS) in Japan has seen a tremendous progress. The first advanced IVHS research was conducted between 1973 and...
Dynamic Stochastic Equilibrium Model in Multiple Vehicle Type Transportation Networks
In this study, a multi-vehicle type dynamic stochastic user equilibrium model (called MDSUE model for abbreviation) is developed. By using MDSUE model, the prediction of departure rates...
Simulation of a Vehicle Platoon Control System for Automatic Highway Using the Fuzzy Control Concept
This paper discusses the concept of the longitudinal control of vehicle platoons on the highways. The paper discusses the simulation of vehicles with non-linear properties, such as air...
Vehicle Lateral Guidance Using a DSP Based Vision System
A practical real-time vision system system which uses a digital signal processing chip to obtain a tracking error for lateral guidance of vehicles at highway speeds is presented. Minor...
Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...
Eilat?A Paradise of Coast and Sealife
This paper describes the development of the existing lagoon in Eilat, Israel, into a modern marina and the dredging of two new lagoons. The existing lagoon was dredged and developed some...
California Department of Transportation Seismic Retrofit Program: The Prioritization and Screening Process
Following the October 17, 1989 Loma Prieta Earthquake, the California Department of Transportation was designated as the lead agency to seismically retrofit all 23000+ public owned bridges...
Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...
Asphaltic Concrete Performance Under High Pressure Tires
A study was conducted by the USAF Engineering and Services Laboratory to evaluate the rutting effects of high pressure tires on Marshall and gyratory designed pavements. Full scale pavement...
Aircraft Flexible Pavement Design in Australia
After World War Two, aircraft pavement design practice in Australia was largely developed from the work done by the U.S. Corps of Engineers. The C.B.R. pavement design method now differs...
Calendar: Bridges 1992
Featured bridges are: Fifficktown Bridge (PA); Crooked River (High) Bridge (OR); High Bridge (KY); Fort Benton Bridge (MT); Linden Street Bridge (MA); Rogue River (Caveman) Bridge (OR);...
Reliability of Bridges in Turbulent Wind
The present study investigates the stability of bridge motion by means of almost sure or sample stability criteria. An asymptotically exact approximation for the top Lyapunov exponent...
Buffeting Response of Bridges
The present study provides a theoretical analysis of the behavior of the response of long-span bridges to turbulent wind loads in the region of stable motion. The analysis is based on...
