Graphical Resource-Based Object-Oriented Simulation for Construction Process Planning
Simulation is a powerful tool for construction process design and optimization. The results of a simulation provide detailed process information, such as resource utilization and idleness,...
Simulation Architecture for Advanced Traffic Management Systems
Trends in Intelligent Highway-Vehicle Systems (IVHS), specifically Advanced Traffic Management System (ATMS) technologies are directed toward better integration between intersection controller...
Modeling the Traffic Flow Impacts of Rehabilitation Activity on Two-Lane Highways
Researchers at the Purdue University have been involved in developing techniques for predicting the operational impacts created by one-way traffic control. These techniques estimate average...
A Short-Term Demand Forecasting Model from Real-Time Traffic Data
Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions...
Implications of Uncertainty in Transportation Control Measures: A Case Study of the Los Angeles Truck Management Program
The Los Angeles Department of Transportation has proposed a peak period travel restriction aimed at heavy-duty trucks on all Los Angeles streets. The ordinance is designed to reduce the...
High Speed Ground Transportation on U.S. East Coast
The United States has entered into a new era of need for domestic improvement. The demand for high speed transportation far exceeds the supply. The increasing congestion of our roads and...
Effect of Future High Speed Ground Transportation on Airport Expansion Needs in the State of Washington
A high speed ground transportation system is proposed to be built in the State of Washington to connect all regions. The proposed system will be approximately 700 miles in length and would...
HSGT?Competitive or Complimentary to Air Travel
The capacity of existing airports to meet increased travel demand is limited. Utilization of high speed ground transportation as a complimentary mode originating from major hub airports...
High-Speed Rail's Prospects in Canada
This paper reviews the attractiveness of high-speed rail in Canada. It summarizes the findings of studies on the subject by VIA Rail, Canada's national passenger rail corporation. VIA...
Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...
Modern Air Pollution Reduction Technology on Platforms in the Pacific OCS
The Pacific Outer Continental Shelf (OCS) along the California coast line has the most sophisticated air pollution reduction technologies implemented in the world. This paper describes...
Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...
Influence of River Mouth Migrations on the Caucasian Black Sea Coast Development
When studying modern coastal and river-issue processes and comparing last century and modern maps some regularities were revealed. River arms, which are upstream the longitudinal sediment...
State-of-the-Art and Dynamic of Some Beaches of the Bulgarian Black Sea Coast
The considerable decrease of the solid flow off in the sea coastal zone and the intensification of the abrasion impact on the shore determined the increase of the coastal protection activity...
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...
Overview of the FAST-TRAC IVHS Program
A major new IVHS initiative, called FAST-TRAC, is taking place in Oakland County, Michigan. It originated as a bottom-up strategy for solving mobility and highway safety problems in this...
