Genesis ? Information on the Move
The access to enhanced real-time travel information is widely accepted as one of the cornerstones of any intelligent highway system. In the majority if IVHS programs currently underway...

IVHS: Applications in Freight and Trucking Operations
This paper discusses the application of IVHS technology to freight and trucking activities. It is argued that because commercial vehicle operators perceive real benefits from IVHS, they...

In-Vehicle Crash Avoidance Warning System Technologies and Human Factors Issues
The National Highway Traffic Safety Administration (NHTSA) estimates that in 1990, motor vehicle accidents cost the nation more that $135 billion in property damage, personal injury and...

Driver Response to Fog Conditions ? An Intelligent Approach
The Roads and Traffic Authority (RTA) on NSW is currently examining options for replacing its Driver Aid System on the F6 Tollway south of Sydney. On this road drivers are affected by...

Collision Avoidance ? State of the Art
Although crashes are rare events, nearly 40,000 individuals are killed in motor vehicle crashes annually in the US. Another 3 million are injured and the societal costs exceed $137 billion...

An Example of Quantitative Evaluation of AVCS Safety
A method has been devised for expressing in absolute terms the effect on safety of various features in the design of an AVCS system. It depends on gathering data from different sources...

A Framework for ATIS Safety
Advanced Traveler Information Systems utilize advance techniques to acquire, process, and disseminate information to motorists. The main purpose of ATIS is to provide motorists with information...

Establishing a Human Factors Focus and Approach for North Carolina's IVHS Efforts
The paper discusses the behavioral and human factors issues associated with the development and operation of North Carolina's CARAT program (Congestion Avoidance and Reduction for Autos...

Digital Mapping for Road Navigation in Japan
In Japan, more than 300,000 vehicles are presently equipped with car navigation systems. Development of these systems had been greatly aided by the completion of a standardized digital...

Technology Transfer: Encouraging the Use of Advanced Technologies in Your Organization
Encouraging the evaluation, use, and development of advanced technologies throughout an organization presents a special challenge, with the rewards of successful implementation far outweighing...

Arterial Street Incident Detection Using Multiple Data Sources: Plans for ADVANCE
An Advanced Traveler Information System demonstration called ADVANCE is being prepared for implementation on an arterial street network in the suburbs of Chicago. This paper will describe...

Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...

Numerical Estimation of Macrodispersivities in Heterogeneous Self-similar Aquifers
Numerical simulations of contaminant transport in a stratified aquifer characterized by a self-similar distribution of hydraulic conductivity were performed. Macrodispersivities were calculated...

Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...

A Two-Dimensional Flow and Hydrogeochemical Transport Model
A two-dimensional flow and hydrogeochemical transport model is designed for estimating the movement and attenuation of chemicals after they are released into subsurface systems. This model...

Simulation of Contaminant Migration Under Conditions of Declining Ground Water Levels
A ground water flow and transport model was developed to simulate the migration of contaminants originating from an industrial site. The development and calibration of the model were based...

Modeling Contaminant Migration from an Unlined Pond
A hybrid one-dimensional (1-D) vertical model coupled with a two-dimensional (2-D) aquifer model was applied to study the fate and transport of arsenic, fluoride, and orthophosphate resulting...

Adjustment of Groundwater Quality Models
Groundwater quality models have been used lately in solving cases dealing with groundwater flow and pollutant transport problems. Finite element method is used in such problems and is...

A Numerical Model for Multiphase Flow and Transport Assessment of Migration of Petroleum Contaminants in the Subsurface
Modeling assessment of the subsurface migration and fate of petroleum hydrocarbons plays a critical role in addressing the environmental impacts of their numerous underground releases...

Investigation of Chloroform Plumes in a Porous Media
A sand box model was used in the laboratory to study the development and stability of the contaminant plume with respect to space and time. Steady, uniform flow velocities were established...
