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...
Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...

Knowledge representation and reasoning, considered of a major importance for building and practical application of the structural reliabilty assessment expert systems, are the issues tackled...
Towards Reduction of the Vulnerability of Multi-Tank Storage Facilities
Accident scenarios in large scale industrial plants show that conventionally designed multi-tank storage facilities are susceptible to domino effects. With the aim to reduce the probability...
Seismic Reliability Analysis for Elevated Pressure Vessels
This paper presents two approaches for assessing the seismic reliability of elevated pressure vessels. A discretized mass mechanical system is used to model the dynamic effects of liquid...
Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...
Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...
Pressure Vessels for Space Station Freedom
Space Station Freedom (SSF) will utilize more than 10 different types of pressure vessels for storage of oxygen, hydrogen, nitrogen and mixed gases at operating pressures ranging from...
Rethinking Flood Control Channel Design
Until recently, the standard method of flood control was channelization�converting a natural stream to a uniform channel cross section. But this single objective approach is coming under...
Earth Pressure Acting on Buried Flexible Pipes in Centrifuged Models
Distributions of both normal and tangential earth pressures acting on three flexible model pipes having different wall thicknesses were successfully measured in centrifuge model tests....
Evaluating Thermal Pressure Changes in Liquid Packed Piping
Theoretical and practical issues involved with the phenomenon of thermally induced pressure change in closed piping systems are investigated. The mathematical derivation of the applicable...
Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...
