Modeling Transportation Outcomes Using Accessibility Analysis

This project is an interdisciplinary study among two research centers at the University of Wisconsin-Madison, with research guidance and support from four state departments of transportation (DOTs). Additional agencies will be recruited for the study through further outreach efforts. This study will advance the use of accessibility metrics, which describe the ability of people to reach jobs and opportunities by different modes of travel, in practical decision-making and, specifically, for predicting transportation outcomes like travel demand and transit use.

Expanding Mobility Options For All: Optimizing And Extending The Biking Infrastructure To Generate Complete Street Networks In Atlanta

The Complete Streets policy aims to transform streets to accommodate multiple modes of travel, including the active modes, such as walking and biking. The objective is to make streets safe and convenient for all persons, including children, the elderly, and the disabled. The proposed project will develop complete multimodal networks to identify potential complete streets using the bike network as a connective thread.

Modern Project Prioritization For Transportation Investments

Historically, transportation agencies’ main priority has been to fund, build and expand highways to safely meet the growing demand for vehicle travel. Their project prioritization processes, therefore, have focused primarily on improving capacity along the most congested major routes. Many of these agencies, however, have experienced a shift in priorities toward the maintenance of existing infrastructure, the facilitation of multi-modal transportation, and the operations and management of existing infrastructure—applications that can be more challenging to fund.

Assisting Vision-Impaired Pedestrians To Cross Streets: An Innovative Acoustic Ranging Approach

This project aims to leverage innovative techniques to develop an intelligent system that assists blind pedestrians to decide when it is safe to cross streets, especially at the uncontrolled crossing locations, where neither traffic lights nor STOP signs are available. While great social resources have been designated to install the Accessible Pedestrian Signals (APS) at intersections to provide guidance instructions to people with visual impairments, it is economically infeasible to equip all intersections/walkways across the nation with such infrastructures.
