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...
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...

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...
Smith's Infiltration Equation and Flooding Infiltrometers
Smith's infiltration equation was developed by examining the output from runs of a physically-based numerical model of one-dimensional infiltration. The model simulated application of...
Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...
Modified Horton Models for Steady Rainfall
When the rainfall rate is less than the initial infiltration rate, direct application of the well-known Horton equation underestimates the total volume of water infiltrating the soil until...
Effects of Climate Change on Drought Risks in the Apalachicola, Chattahoochee, and Flint River Basin
Possible effects of climate change on the Apalachicola-Chattahoochee-Flint (ACF) River basin is simulated with a computer model. Model inputs are monthly temperature and precipitation...
Impacts of Climate Change on Evapotranspiration and Runoff in the Tennessee River Basin
Recent climate change studies using general circulation models demonstrated the potential for a 1 to 3?C warming in North America, as well as increases in precipitation and evaporation...
