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...
Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...
Minnesota Department of Transportation Experience in the Application of Advanced Traffic Management Systems
The Minnesota Department of Transportation (Mn/DOT) began deploying Advanced Traffic Management Systems (ATMS) in the early 70's. The Interstate 35W just south of the Minneapolis...
Academic Research Efforts in the GuideStar IVHS Program
The Minnesota Department of Transportation (Mn/DOT) and University of Minnesota officials, realizing that Minnesota was among the leaders in both research and implementation of advanced...
Design Experience Gained Through Physical Modeling of Small-Craft Harbors
A research work unit has been initiated to determine the state-of-knowledge of small boat harbor design. Existing design criteria for small-craft harbor design is based primarily on 'rule-of-thumb'...
Predicting Sedimentation in Shallow Draft Coastal Ports
The U.S. Army Engineer Waterways Experiment Station is conducting a study to develop and improve design guidance for shallow draft coastal ports. As part of this effort and to fill gaps...
A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...
Pavement Design by Elastic Layer Theory
The U. S. Army Engineer Waterways Experiment Station has been developing methodology by which airport/airfield pavements can be designed based on elastic layered analysis for the Federal...
Landing on Frictionless Surfaces
Who in his right mind would deliberately land an airplane on a frictionless surface? Unfortunately, professional pilots occasionally encounter situations where the friction between rubber...
Applications of Advanced Technologies in Transportation Engineering
This proceedings,
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...
Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
Probabilistic Concepts of Redundancy and Damage Tolerability for Structural Systems
Intermediate states of structural systems (prior to system collapse and after component loss) are focused herein. This area relates to important issues such as redundancy and damage tolerability....
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...
The Estimation of Allowable Strength Based on Fatigue Reliability of Welded Part and Base Metal of Rail in Korea
In the allowable stress design, the safety of structures have been ensured by safety factor based on static strength. Under dynamic loading condition, the allowable stress based on allowable...
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...
