Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...

Ecolocy-Conscious Submerged Breakwater
A submerged breakwater makes incident rough waves small when their heights exceed a certain level on the site, though the other waves lower than the level are not so much affected by the...

Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...

Systems for Control of Environmental Conditions in Regional Marine Ecosystem?A Fundamental Study
This study is being executed as a part of the consolidated research carried out by Nihon University. The study is being developed basically by two main research groups; the first group...

IVHS Strategic Planning for Washington State
Implementation of IVHS technologies must be based on a strategic planning approach. The strategic plan must consider regional and statewide needs and should prompt integration of IVHS...

Estimation of Queue Lengths in Urban Road Networks
In this paper we present a new scheme for the surveillance of traffic state on a link of an urban road network. It is shown that measurements of traffic counts and speed values from a...

Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...

A Dynamic Real-Time Incident Detection System for Urban Arterials?System Architecture and Preliminary Results
This study presents a system which is capable of detecting incidents in real-time and adjusting itself to traffic dynamics through the embedded learning mechanism. The entire system consists...

Seattle Area Traffic Management System Upgrade
The Washington State Department of Transportation (WSDOT) implemented the first components of this freeway monitoring and control system in 1967. A major upgrade to this system was completed...

Advanced Highway Control on the Central Artery
The Boston Central Artery/Tunnel project involves highways 190 and 193, in downtown Boston, placing underground 7 miles of four to eight lane tunnels. The project, with 37 lane-miles underground,...

Metering Strategies Applied to Signalized Networks
This paper describes the development and adaptation of ramp metering strategies for use in signalized networks. The strategies were developed in simulation environment using the micro-simulation...

Neural Networks in Freeway Control
Hierarchical control strategies have been proposed for freeway optimum control since the 1960's. Multi-layer hierarchical control optimizes system performance to determine a nominal metering...

IVHS-Organizational Structure and Staffing
Continuing technology advances in IVHS present challenges that many states are unable to meet with their current staffs. Only a few states have recognized the need to plan the need to...

A Neural Network Model for Data Fusion in ADVANCE
As current state of the art technology on smart cars and Smart Highways is processing, applications of advanced technologies in transportation engineering are becoming more and more important....

Modeling Route Guidance Systems Using the Integration Model
In-vehicle Route Guidance Systems (RGS) have been proposed as a potentially cost-effective means of alleviating the impact of traffic congestion in urban areas. This paper describes means...

Simulation-Based Training for Transportation Management Center (TMC) Operators
Effective simulation-based training for Transportation Management Center (TMC) operators enables operators to make the best use of their TMC and thereby to improve the efficiency and safety...

A Simulation and Data Management Environment for Off-Line Testing of IVHS Technologies and Strategies
CA is engaged in a rapidly expanding statewide effort to test and deploy advanced traffic management and traveller information systems to mitigate congestion and increase mobility. To...

An Integrated Route Assignment and Traffic Simulation System with a Massively Parallel Computing Architecture
This research presents two critical issues in the development of an integrated route assignment and traffic simulation system of ATMS-ATIS applications. The first issue addresses the conceptual...

Simulation of the Dynamic Traffic Flow on Urban Road Network
Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion. In this paper, the route choice behavior...

Detection of Incidents and Traffic Disturbances in Freeways
This research aims to develop methods for detecting incidents and compression waves through simulation. The detection methods are based on a macroscopic traffic flow model that focuses...
