New Lidar System Pinpoints Pedestrian Behavior To Improve Eficiency And Safety At Intersections, Taylor Li, Sirisha M. Kothuri, Xianfeng Terry Yang
TREC Project Briefs
Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new LiDAR system to improve data collection at intersections.

In Part 1 of ‘Encountering Berlant’, we encounter the promise and provocation of Lauren Berlant's work. In 1000-word contributions, geographers and others stay with what Berlant's thought offers contemporary human geography. They amplify an encounter with their work, demonstrating how a concept, idea, or style disrupts something, opens up a new possibility, or simply invites thinking otherwise. The encounters range across the incredible body of work Berlant left us with, from the ‘national sentimentality’ trilogy through to recent work on negativity. Varying in form and tone, the encounters exemplify and enact the inexhaustible plenitude of Berlant's thought: fantasy, the case, …

Factors Influencing Bike Share Among Underserved Populations: Evidence From Three Us Cities, Jennifer Dill, Jiahui Ma, Nathan W. Mcneil, Joseph P. Broach, John H. Macarthur
Urban Studies and Planning Faculty Publications and Presentations
There is evidence that lower-income and people of color (POC) in the U.S. do not use bike share as much as higher-income and white people. Using data from residents living near stations in New York, Chicago, and Philadelphia, our analysis examines reasons for these disparities. While smaller shares of POC are members (vs higher-income white people), large shares of POC are interested in bike share. Among POC, having positive attitudes about bicycling and having family and friends that use bike share are strong predictors of interest in bike share. POC are also motivated to use bike share for recreational reasons. …

Statistical Inference For Multimodal Travel Time Reliability, Avinash Unnikrishnan, Miguel Figliozzi, Subhash C. Kochar
TREC Final Reports
Travel time reliability is a key metric of interest to practitioners and researchers because it affects travel choice and the economic competitiveness of urban areas. This research focuses on three travel time reliability metrics – buffer index, modified buffer index, and the relative width of travel time distributions. The key novel contributions of this research include using the multivariate delta method to prove that the sampling distributions of the three travel time reliability metrics are asymptotically normal. The asymptotic standard error for the three reliability metrics is derived. The asymptotic normality and the standard error result are used to arrive …

50 Years And Counting: Why Environmental Preservation Is Embedded In Oregon Culture, Carl Abbott
Urban Studies and Planning Faculty Publications and Presentations
In the years following World War II, suburban growth began consuming Willamette Valley farmland. Increasingly affluent families were snapping up vacation properties with mountain and ocean views. Oregonians in the latter half of the 1960s responded with conferences, reports and finger-wagging at the bad example of California. In 1969, the legislature acted with Senate Bill 10. The legislation established land-use regulation as a state concern, requiring local governments to develop land-use plans in line with 10 statewide goals. The intention was good, but the measure lacked teeth for monitoring and enforcement. McCall promised to fix the problems when he ran …

Mobility For The People: Evaluating Equity Requirements In Shared Micromobility Programs, Anne Brown, Amanda Howell, Hana Creger
TREC Final Reports
Technology-enabled shared micromobility services have expanded mobility for some travelers, but significant barriers to use limit their uptake among certain groups. To address these barriers, cities and professional transportation organizations have undertaken two distinct efforts to operationalize equity in shared micromobility services: 1) drafted equity frameworks in an attempt to clearly define equity within the transportation context and to provide guidelines for what cities should consider when designing equity-based mobility programs; and 2) some cities have attempted to ameliorate access disparities by establishing new requirements for shared micromobility programs. Both equity frameworks and program requirements mark important steps to operationalizing …

Transit And Active Transportation Use For Non-Commute Travel Among Portland Transit-Oriented Development Residents, Jennifer L. Dill, Nathan W. Mcneil
Urban Studies and Planning Faculty Publications and Presentations
Transit-oriented development (TOD) seeks to promote non-single occupancy vehicle travel by placing dense residential and mixed-use buildings near high-capacity, high-frequency transit. Most research to date on the impact of TODs on travel behavior has focused on commute trips; however, many trips are for non-work purposes, and a sizable portion of the population does not commute to work. This study utilizes a set of surveys, conducted between 2005 and 2019 in the Portland OR region to assess factors associated with whether or not, and how often, TOD residents walk, bike, or take transit for home-based non-work trips. Findings show that about …
