Research Objective: Develop a compendium of the best and innovative methods and tools for transportation planning and project development analyses. Task 1: Develop criteria for evaluating the effectiveness of the

TERI Database Administrator Notes:  Not recommended at present time by 2009 Environmental Process Subcommittee. State departments of transportation, as well as regional transportation agencies and organizations, (herein after ‘transportation agencies’)

This research idea was developed as part of NCHRP Project 24-27(03) “Evaluation of Bridge-Scour Research: Geomorphic Processes and Predictions,” and addresses three Focus Areas (Environmental Considerations in Planning, Project Delivery/Streamlining,

The objective of this research is to develop approaches for evaluating long-term regional strategies for the use of alternative vehicle power sources. The vision is that the approaches developed may

Transportation professionals, including planners and engineers, desire to avoid conflicts and reduce mitigation costs, thereby increasing the reliability and predictability of transportation design processes.  Further, SAFETEA-LU requires involvement of participating agencies

Scope:  With continual technological advances in tools like GIS, remote sensing, and computer software, the transportation industry has at its disposal increasingly more capable tools to perform transportation planning and

Road salt runoff is a seasonal phenomenon, largely confined to the late-winter to spring months. For most northern biota, this is a lag period of growth when they are least

The research regarding the reduction of the adverse environmental impact through highway design is still in its infancy. Furthermore, highway design manuals/guidebooks do not provide any information on environmentally-friendly designs.

Park-and-ride programs have been expanding for several years.  For example, in Virginia they continue to gain popularity among commuters in both major metropolitan areas and even in rural areas.   

This study will assess how advances in non-market economic valuation methods of ecoservices from natural systems can be incorporated into current approaches to EIS analysis and Benefit-Cost Analysis of proposed

Snow avalanches can have catastrophic effects on highway travel by blocking roadways entirely as well as the potential for both property damage and loss-of-life consequences.  There are also severe economic

Highway agencies place Winter Weight Premiums (WWP) and Spring Load Restrictions (SLR) during the winter and spring seasons when the performance of pavement structure changes due to winter freeze and

Utilizing the results of NCHRP 25-25, Task 23 – Guidelines for Environmental Performance Measurements Final Report, investigate using positive performance measures to obtain reductions in criteria pollutants and greenhouse gas

Currently field offices in the US Fish and Wildlife Service (Service) use a variety of methods to determine if species suitable habitat is in a project area. Recently the New

Objective: Analyze environmental and energy benefits of increased efficiency in the Northeast Corridor as a result of improved freight operations. Background: A great deal of effort and attention is being

Wetlands are among the world’s most ecologically productive and economically important environments, but they are also one of the world’s most endangered environments. Approximately 53% of wetlands in the lower

The proposed study would incorporate No Adverse Impact floodplain management and mitigation into future planned transportation projects. The objective is to evaluate potential flood risk for transportation projects early in

The Wisconsin Department of Transportation (WisDOT) has built a number of structures to facilitate Aquatic Organism Passage (AOP) over the last decade, several of which have been designed in accordance

Cost benefit analysis of culvert and bridge maintenance often omit aspects of ecological integrity. Over the lifetime of a stream crossing, the structure type will impact biological communities such as

This study presents thermal snow melting methods utilizing electric heating cable, geothermal, tunnel water heat, and solar that can be applicable for various locations on modern road networks. Compared with

Bats across the United States are threatened by a relatively new fungal disease known as white-nose syndrome (WNS). WNS has resulted in bat population declines of over 90% in parts

Connectivity among populations and habitats is important for a range of ecological processes, including gene flow, migration between summer and winter range, demographic rescue, dispersal, range expansion, and population persistence.

New technologies have made it possible to collect and characterize large amounts of data through remote sensing and other techniques. Sensors, drones, and powerful data analytics have the potential to

The objective is to develop a reliable methodology for determining and relaying the secondary and cumulative effects related to the implementation of connected and automated vehicles in environmental documentation. Develop

The objective of this research is to understand how and to what degree the full delegation of environmental permit responsibilities (and associated penalties for noncompliance) may change contractors’ construction sequencing,
