Environmental Impact Assessment of Rail Infrastructure in Illinois

Specifically, this study has developed an integrated tool that incorporates key metrics to assess the environmental, ecological, economic and social impacts of rail transportation in a Geographic Information System (GIS) framework.

Objective:

Under the National Environmental Policy Act (NEPA), proposed rail projects are subject to a lengthy and expensive environmental evaluation process. Sponsored by the USDOT-National University Rail (NURail) Center Consortium, this study aims to increase the effectiveness and efficiency of environmental impact assessment of rail infrastructure by providing a system view of sustainability and a one-stop rail planning database.

Strategy:

Environmental Aspect of Rail Research MethodologyCompared to existing studies and databases with similar objectives, this study is particularly informative and timely for two principal reasons.

First, it has incorporated state-of-the-art academic research findings as well as legislation and government guidelines in a comprehensive “Sustainable Rail Scorecard” that covers the efficiency, safety, public health, ecological stress, emissions, and socioeconomic impacts. The Scorecard evaluation can be conducted using a tiered approach that specifies meeting minimum regulatory requirements or a “best practice” sustainable alternative.

Second, this study simulates and visualizes the potential environmental impacts of proposed rail infrastructure at a refined geographical scale (e.g., the vicinity of grade crossings), based on the speed, traffic volume, and occupancy of the rail transport system. Connecting environmental impacts with neighborhood background information, such as land uses, demographic characteristics, and environmental quality, this study identifies high priority and sensitive areas for sustainable rail planning and management in the Chicago metropolitan region

Expected Results or Products:

This project provides a web GIS tool that integrates sustainability metrics and facilitates a rapid assessment before a formal NEPA process is implemented for a rail project. The web tool enables users to specify a geographic area in Illinois and obtain a summary of environmental, demographic, and rail infrastructure data of interest. Transportation professionals and environmental planners can use this application to consider a wide range of impacts early in the decision-making process, before significant funds and time have been devoted to project design. This will alert transportation and environmental professionals of the need to perform a targeted assessment, and/or to coordinate among multiple departments in both rail system planning and operation processes. This tool is also anticipated to promote community awareness and involvement; public citizens can easily obtain information about the potential impacts of proposed or ongoing projects for advocacy in environmental justice in their community.
