Rail Replacement Planning: A Knowledge System Approach
Replacer is a knowledge system that provides a consistent means for developing plans for rail replacement. It was developed, tested, and evaluated in cooperation with Burlington Northern...

A Preliminary Systems-Level Evaluation of Automated Urban Freeways
Transportation planners predict that traffic congestion will increase dramatically in the future. With 63% of all congestion on urban freeways, much of it in high-density areas, traditional...

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....

An Application of Expert Systems to Traffic Signal Control
Signal Control at Isolated Intersections (SCII) has been developed to emulate an adaptive controller using AI technology. It is an application of expert systems to the real-time traffic...

A Real-Time Traffic Diversion Model: A Conceptual Approach
The development of a real-time traffic diversion control system for integrated freeway and arterial networks, as part of the most currently envisioned Intelligent Vehicle/Highway System...

A New Approach for Real-Time Prediction of Traffic Demand-Diversion in Freeway Corridors
An adaptive method is developed for real-time prediction of demand and diversion of traffic flow at on-ramp areas of freeway corridors. The prediction method explicitly treats the time-variant...

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...

Effectiveness of Real-Time Information Strategies in Situations of Non-Recurrent Congestion
The effect of real-time information on the performance of a traffic commuting corridor in situations of non-recurrent congestion is studied using a dynamic simulation model. Non-recurrent...

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...

Observation and Modeling of Mobile Environment
Perception of the environment in a mobile robot is a difficult task. Other moving objects and various changes in the environment and motion of the robot must be handled together. Control...

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...

Reef Breakwater Design for Lake Michigan Marina
An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The...

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'...

Physical Model Testing of Barbers Point Harbor and Marina Complex
A three-dimensional, physical model study of the Barbers Point, Hawaii harbor and marina complex is being conducted at the US Army Engineer Waterways Experiment Station, Coastal Engineering...

Simplified Tidal-Flushing Model for Small Marinas
This paper describes the development and application of a new water quality screening model - STEAM (Simplified Tidal Embayment Assessment Model). This model simulates the first-order...

Predictive Techniques for Marina Water Quality Assessment
The construction of new marinas in coastal areas requires as assessment of potential impacts on water quality as a part of the permit process. This paper summarizes a study sponsored by...
