Webinar: What Do We Know About Location Affordability in U.S. Shrinking Cities?

WEBINAR SLIDES

WEBINAR SUMMARY

Traditionally the discussion about affordability has focused on housing, but HUD’s Location Affordability Index (LAI), released in 2012, helped to elevate the conversation by expanding the focus to include households’ transportation costs. In the...

OVERVIEW

Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? This study examines housing costs for households living in TODs.

KEY LEARNING OUTCOMES

  • Learn how many TODs there are currently in the U.S. and what methodology was used to identify them.
  • Learn what share of housing in TODs is affordable, what are the relative shares of designated versus naturally occurring affordable units and whether the level of affordability is the same for families of different sizes.
  • Learn ...

Adam Moore: Bus Stop Air Quality: An Empirical Analysis of Exposure to Particulate Matter at Bus Stop Shelters

Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based pollution, including particulate matter, due to their proximity to the roadway. Current guidelines for the location and design of bus stops do not take into account air quality or exposure considerations. This study compares the exposure of transit riders waiting at three-sided bus stop shelters that either: 1) face the roadway traffic or 2) face away from the roadway traffic. Shelters were instrumented with air quality monitoring equipment, sonic anemometers, and vehicle counters. Data were collected for two days at three shelters during both the morning and afternoon peak periods. Bus shelter orientation is found to significantly affect concentration of four sizes of particulate matter: ultrafine particles, PM1, PM2.5, and PM10. Shelters with an opening oriented towards the roadway were consistently observed to have higher concentrations inside the shelter than outside the shelter. In contrast, shelters oriented away from the roadway were observed to have lower concentrations inside the shelter than outside the shelter. The differences in particulate matter...

This webinar presents a novel method that utilizes location-based services for collecting public transportation data.

A NITC-funded project at the University of Oregon will be presented that focuses on the development and evaluation of a mobile application based on Bluetooth low energy technology sensors and geofencing technology for crowdsourcing data collection.

The application was employed in a case study using Lane Transit District’s express bus system in the Eugene-Springfield area in western Oregon. The results show that using these types of location-based services offers an effective approach to collecting richer data than traditional means, while requiring only minimal...

Summary: The Federal Transit Administration's (FTA) discretionary New Starts program is the federal government's largest discretionary funding program. From heavy to light rail, from commuter rail to bus rapid transit systems, the FTA's New Starts program has helped to make possible hundreds of new or extended transit fixed guideway systems across the country, including most of TriMet’s light rail extensions and WES commuter rail. Beginning in 2001, FTA has required project sponsors to prepare a Before and After Study report on the effectiveness of planning and implementation of New Starts and Small Starts projects. The studies focus on five transit characteristics – project scope, capital costs, operating and maintenance costs, service levels, and ridership behavior – and compares these characteristics at various planning milestones, as well as before and after implementation of the project.

TriMet, in conjunction with FTA, has completed or nearly completed Before and After Study reports for three projects – Interstate MAX, WES Commuter Rail, and the Green Line – and is in the process of working on two more. This presentation will briefly describe the federal New Starts program, FTA requirements for Before and After Studies, summarize...

Abstract: In transportation planning and engineering, market segments or groups of individuals with varying attitudes and travel behavior are often identified in order to define a set of policies and strategies targeted at each segment. Examples include residential location choice studies, electric vehicle adoption and the marketing of public transit options. Defining market segments is common in the marketing literature, typically based on observed socioeconomic characteristics, such as gender and income. However, in addition to these characteristics, travelers may also be segmented based on variations in their observed travel and activity patterns. The activity-based approach to travel demand analysis acknowledges the need to analyze the travel patterns of individuals, conceptualized as a trip chain or tour, as opposed to individual trip segments. This has implications for identifying markets segments based on travel patterns which needs to distinguish between the sequencing and timing of travel choices and activities, in addition to the actual travel choices and activities. One approach that holds promise is pattern recognition theory which has wide applications in image analysis, speech recognition and physiological signal processing. In this study, pattern recognition methods are applied to observed daily travel and activity patterns from Oregon to identify travel market...

Summary: In an era of reduced government funding, transit operators struggle to reduce operating costs and increase revenues. Energy costs account for an important share of the total costs of urban and suburban bus operators. Using a case study of one operator in Lisbon, Portugal, this talk will expand upon the empirical research on bus transit operation costs and identify the key factors that influence the energy efficiency of the overall bus fleet. Our results of a multivariate analysis find the following dimensions influence transit energy efficiency: vehicle type, commercial speed, road grades and bus routes; and to a lesser extent elements related with engine failures and malfunctions. In addition to these findings, the methodology is a decision-support tool for the bus operator in optimizing energy efficiency. The transferrability of these results and analytical tools to other contexts will also be discussed.

Summary: Transit serves as backbone infrastructure for many regional and local visions for sustainable urban development. Also, many modern policies predicate transit funding on the potential for transit-oriented development (TOD) near proposed infrastructure investments. However, little research has examined how TOD considerations have informed transit planning. This presentation discusses the results of recent dissertation research that fills this gap. Through multiple transit project case studies and interviews with nearly 100 transit planning professionals, this research categorized how transit projects across 19 U.S. regions were designed to foster TOD and how transit planning professionals identified TOD opportunities as projects were planned. During interviews, many professionals lamented the amount of real estate development that had occurred around the transit projects they helped plan. Analysis revealed that the ways in which professionals identified TOD opportunities helped to explain disconnects between their expectations and actual outcomes. The findings raise concerns about the effectiveness and efficiency of transit planning practice in the age of transit-oriented development and point to potential policy and practice changes that could address the issues.
