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...
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...
Analysis of Nonstationary Random Vibrations
Nonstationary random vibrations occur in structural mechanics as well as in vehicle dynamics. Very often the nonstationary excitation process can be modelled as stationary white or colored...
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...
Lifetime-Maximum Load Effect for Highway Bridges Based on Stochastic Combination of Typical Traffic Loadings
An efficient and accurate method is proposed for probabilistic assessment of lifetime maximum load effect on highway bridges caused by traffic load. Probability distribution of the lifetime...
Bridge Live Load Models
This paper describes the analysis of weigh-in-motion data and the conclusions drawn. Statistical distributions of the effects induced in typical bridges due to single vehicle events are...
On the Dynamic Response of Bridges by Oscillating Vehicles on Rough Surfaces
The spectral theory is applied to the response of bridges under a Poissonian stream of vehicles moving with constant speed over the bridge. The vehicles are modeled as oscillators with...
A Reliability Analysis of Aerospace Structures Subject to Thermal Mechanical and Flight Loads
Aerospace structures are subjected to various flight loads throughout their service life. In certain anticipated missions, significant thermal stresses will be generated through atmospheric...
Unlocking Arena Gridlock
The Charlotte Coliseum features a $22 million reversible lane system, which provides easier access to and from 8,000 parking spaces. To improve access to the arena, a 3.6 mi road extension...
