New Probe Data Sources To Measure Cycling Behavior And Safety, Christopher Cherry

PSU Transportation Seminars

Emerging probe data sources from smartphones on on-board devices are able to measure behavior of cyclists with very high resolution. From this, for the first time, we are able to measure relatively precise behavior that allows new insights into exposure, route choice, safety behavior, or technology choice. Probe data, merged with other data sources, can begin to develop a more complete picture of cyclists on-road behavior.

This presentation will offer examples of analyses done to investigate cyclists behavior using app-based and on-board GPS data in the context of individual cyclists behavior (i.e., app users) and behavior of bikeshare users (i.e., …

A Multiagent-Based Approach For Vehicle Routing By Considering Both Arriving On Time And Total Travel Time, Zhiguang Cao, Hongliang Guo, Jie Zhang

Research Collection School Of Computing and Information Systems

Arriving on time and total travel time are two important properties for vehicle routing. Existing route guidance approaches always consider them independently, because they may conflict with each other. In this article, we develop a semi-decentralized multiagent-based vehicle routing approach where vehicle agents follow the local route guidance by infrastructure agents at each intersection, and infrastructure agents perform the route guidance by solving a route assignment problem. It integrates the two properties by expressing them as two objective terms of the route assignment problem. Regarding arriving on time, it is formulated based on the probability tail model, which aims to …

Massachusetts Urban Bicycle Preparedness, Rick L. Sheiber

Instructional Design Capstones Collection

Since 2007, Boston has made tremendous strides in shedding its designation by Bicycling Magazine as one of the “Worst Biking Cities” (Zezima, 2009, p. A12) by designating over 92 miles of bike lanes throughout the city and introducing bicycle initiatives like Boston Bikes, the Hubway bicycle sharing program. These efforts have resulted in a dramatic rise in the number of cyclists in Greater Boston and a decrease in accidents involving bicycles ((Pedroso, Angriman, Bellows & Taylor, 2016). While the quantitative research has been primarily positive, a 2017 survey initiated LivableStreets and the Longwood Area Cyclists of commuters in the Longwood …

California's Paradigm Shift From Los To Vmt As A Transportation Impact Metric: Policies, Politics, And Possibilities, Robert Liberty, Lynn Peterson

PSU Transportation Seminars

As part of California's effort to reduce greenhouse gas emissions, the state has passed a law leading to a radical shift in how it analyzes the traffic impacts of new land use developments and transportation projects. SB 743's goal is to "more appropriately balance the needs of congestion management with statewide goals related to infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions."

The new measure of transportation impacts will be based on vehicle miles traveled (VMT) instead of level of service (LOS). This ground shift has broad implications for lead agencies, planners, MPOs, …

Assessing The Impact Of Land Use And Travel On Carbon Dioxide Emissions In Portland, Oregon, Zakari Mumuni

Dissertations and Theses

The negative consequences of sprawling metropolitan regions have attracted attention in both academia and in practice regarding how to better design settlements and alter travel behavior in a quest to curtail vehicle emissions. Studies that have attempted to understand the nexus between land use, travel and vehicle emissions have not been able to address the issue of self-selection in a satisfactory manner. Self-selection occurs when households choose their residential location based, in part, on expected travel behavior. This non-random experience makes the use of traditional regression frameworks that strongly rely on random sampling, unsuitable. This replication study's purpose was to …

"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

New transit infrastructure is a double-edged sword for low-income renters: one the one hand, increased mobility supports access to jobs and critical services; but if transit-oriented development fails to include and preserve affordable housing, they may be pushed out by rising rents. The question of whether public investments spur gentrification and displacement have created intense controversy around planned transit extensions in our region. My research on precarious rental housing illuminates the specific mechanisms of housing displacement and challenges for housing affordability in the single-family/duplex and the large multifamily rental market. The loss of low-cost housing is occurring even without new …
