  • Economic Benefits of Productivity Increases through Truck-to-Rail Mode Shift in Freight Transport

    This study’s goal is to develop an analytical framework to apply the CGE model in the analysis of freight mode shifts through the simulations of plausible impacts of such change. The framework developed in this study can also be applied to the analysis of the effects of fuel price increase or policy measures such as carbon tax

  • Environmental Impact Assessment of Rail Infrastructure

    Study to assist the effects on the environment from new or expanded railroad infrastructure.

  • Evaluation of Bridge Inspection and Assesment in Illinois

    This project explores these opportunities and through literature review, interviews, surveys, field observation and field-testing develops recommendations to IDOT for the acquisition and use of these technologies. Evaluation criteria will be identified and an evaluation methodology developed in the course of the project.

  • Exploring the Potential for Off Peak Delivery in Metropolitan Chicago: Research Findings and Conclusions

    Present research and implementation options as a foundation for future efforts by interested organizations to consider and adopt strategies and methods to shift more deliveries to off-peak times.

    This report serves as the basis for launching a pilot program and presents research and options as a foundation for future efforts by interested organizations to consider and adopt strategies and methods to shift more deliveries to off-peak times.
  • Framework for Assessing the ROI for High-Speed and Intercity Rail Projects

    This report lays out a framework for presenting the return on investment for intercity passenger rail.

  • Housing-Transportation Cost Trade-off Implications for Urban Sprawl

    The purpose of this report is to examine the transportation costs of sprawling places in the context of the housing-transportation cost trade-off. The line of reasoning within this study stems from the housing-transportation trade-off. The proposition is that households have a portion of their budget that they allocate to the sum of housing and transportation costs.

  • Increasing Mobility Through Enhanced Transit Connectivity

    The research for this paper has been guided by this goal: everyone in the Chicago area should have integrated, ubiquitous and affordable mobility options, while public and private resources are used efficiently and effectively toward that end.

    A review of the changing world of transit in the region, including several public transit innovations, emerging technology, explosive growth of rideshare services and the possible impact of autonomous vehicles.
  • Integrated Approaches to EV Charging Infrastructure and Transit System Planning

    The aim of this empirical study is to provide policy insights into integrating EV infrastructure development with transit systems. While the existing EV charging structure has often been driven by the private sector to facilitate EV adoption, this study promotes transit uses and EV adoption at the same time. With a focus on multi-modal trips, this study explores opportunities related to underutilized parking spots that are suitable for both EV charging and transit connections, either on site or in proximity to transit stations.

  • Integrated Modeling of High Performance Passenger and Freight Train Operation Planning on Shared Use Rail Corridors: A Focus on the US Context

    This paper studies strategic level train operation planning on shared use passenger and freight rail corridors. We explicitly consider passenger schedule delay and freight foregone demand as a function of train schedules, which are largely ignored in previous research. In particular, incorporating passenger schedule delay makes the passenger train scheduling a quadratic integer programming problem.

  • Integration of Transportation for Improved Mobility

    The objective of this study was to examine ways in which integrating transportation modes may improve mobility in the region. The study is needed due to the high levels of congestion on roadways in northeastern Illinois.

  • Lake County Coordinated Paratransit Study

    The research team collaborated with the Lake County Coordinated Transportation Committee to conduct a transit needs assessment of elderly and disabled residents and inventory of existing services in order to identify gaps in service and opportunities for coordination.

  • Leveraging Connected Highway Vehicle Platooning Technology to Improve the Efficiency and Effectiveness of Train Fleeting Under Moving Blocks

    Train following control algorithms developed through this research are critical to future attempts to increase capacity and efficiency through advanced train control systems with moving blocks.

  • Mobility Management: State of the States Report

    It was the objective of this report to shed light on these mobility management networks at the state level with the help of an electronic survey of state mobility managers and affiliated stakeholders. The survey was sent to 49 transportation professionals, each representing a different state. A key finding: Strong political backing is necessary as evidenced by the fact that most networks were brought into existence with legislative action, with the network being led by the respective state DOTs.

  • Mode Choice Modelling Using Personalized Travel Time and Cost Data

    The study reveals how some alternative modes’ travel information are limited or unavailable in the traditional travel time skim matrix, which must be taken in to account in our mode choice models. Also, statistics regarding available alternatives and the constraints people encounter when making a choice are presented and considered accordingly. In order to examine the importance of accurate alternative information for mode choice modeling, two mode choice models were then developed for comparison

  • National Survey of US Public Transit Agency Experience with and Response to Extreme Weather Events

    This report provides a descriptive summary and assessment of aggregate survey responses. Findings are presented in four parts: recent experience with extreme weather; perception of weather and climatic risks; assessment of organizational priority, capacity and challenge of managing extreme weather; organizational responses and adaptation to extreme weather events.

    Several key findings were made from the national survey on extreme weather events.
  • Off-Peak Delivery: A Pilot Project for the Chicago Region

    The objective was to complete research needed to launch an OPD pilot program in Chicago by year-end 2015.

  • Pedestrian Safety in Illinois, 1990-2000

    Cook County’s fatality rate per population was only exceeded by three other counties Williamson, Kankakee and Effingham. In suburban Chicago, McHenry and DuPage had fatality rates less than one-third of the rate in Cook County. On a national scale, DuPage has the second lowest rate among counties with over half a million people. When the degree of walking is considered Cook County falls within the middle of the Chicago-area counties. The lowest rates are in DuPage and Will Counties and the highest are in Kane and Will Counties.

  • Pedestrian/Bicyclist Warning Devices and Signs at CTA Rail-Highway Grade Crossings

    The objective of this study was to contribute to the still limited research on pedestrian and cyclist safety at rail grade crossings by expanding the scope of a previous study (Metaxatos and Sriraj, 2013) to include rail grade crossings in metropolitan Chicago with rail operations by the Chicago Transit Authority.

    This study identified seven locations at CTA rail grade crossings as suitable to conduct paper/pen manual user surveys for pedestrian/cyclist activity; a total of 211 surveys were gathered.
