Over the past decade, the rapid development and adoption of mobile computing and telecommunications technology has begun to disrupt established business models based on providing mobility services that were previously available primarily through the public sector (particularly public transit agencies) or that were privately provided through households’ and firms’ directly-owned and operated vehicles. Transportation has entered an era of immense change, with many transportation network companies (TNCs) both complementing and competing with public transit.
Despite disparity in methods and efforts, many Metropolitan Planning Organizations (MPOs) are seeking to incorporate equity in their planning and project prioritization processes. Yet MPOs often focus on avoiding adverse and disproportionate impacts of projects on traditionally underserved communities, without an equal focus on developing projects that advance the needs of these communities. In addition, although the economic benefits of projects are a key priority to MPOs in the project prioritization process, few MPOs screen and rank projects based on whether they specifically improve access to opportunity for low income and minority communities.
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.
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.
Roadway lighting is roadway infrastructure used to ensure nighttime safety and security for multimodal road users. Key tasks in nighttime safety management include periodically measuring roadway lighting levels, diagnosing lighting performance and safety impacts, and providing decision-making support for lighting maintenance and upgrade.
According to the latest Urban Mobility Report published by Texas A&M Transportation Institute (TTI), urban traffic congestion, mostly generated on urban arterials, is a persistently growing problem. In 2017, the total congestion cost in 494 U.S. urban areas was $166 billion and the extra travel time was 8.8 billion hours. Urban congestion is negatively affecting the economy and society of U.S. To solve the urban congestions, the University of Texas Arlington and Georgia Institute of Technology will collaborate to investigate a new Public-Private-Partnership (PPP) Data Sharing Policy through developing a novel arterial system performance monitoring and optimization system.
Lateral water drainage on roadways is important to ensure safe and efficient operation and structural condition of the pavement. Pavement rutting could lead to failure in draining water, which poses a hydroplaning risk to drivers due to ponding and loss of skid resistance in wet weather. Traditional data collection methods to identify pavement sections with deformation such as rutting are time-consuming, labor-intensive, and require data collectors to be located on the road, which poses a safety hazard.
Roadway lighting is a basic roadway infrastructure to ensure nighttime safety and security for all road users (motorists, pedestrians, cyclists, and transit passengers). To cost-effectively maintain a roadway lighting system, key tasks in infrastructure management include periodically measuring roadway lighting levels, diagnosing lighting performance based on collected data, and providing decision-making support for maintenance and improvement.
Transportation communication towers facilitate telecommunications that are essential for Intelligent Transportation Systems (ITS) applications in advancing transportation safety and mobility operations. State DOTs and other agencies spend considerable amount of dollars annually to maintain towers as they are an integral part of their assets. The advancement in unmanned aerial vehicle inspections have propelled its application for assessing the infrastructure condition, especially where traditional monitoring methods are limited by the inaccessibility to hard-to-reach areas.
One of the main challenges of cancer patients is making decisions simultaneously about their cancer treatments and careers because of many factors, including side-effects and the cost of treatments. For example, the most common side-effect of cancer treatments is dizziness, which reduces the ability of patients in driving. This minor side effect might completely change cancer patients’ lives if their only mode of transportation is driving.
