Ludmilla D Pavlova

In 2013 the University of Massachusetts, on behalf of the University of Massachusetts Building Authority and Massachusetts Division of Capital Asset Management and Maintenance (DCAMM), submitted an Expanded Environmental Notification Form for the University's 2012 - 2021 Capital Improvement Plan to the Executive Office of Energy and Environmental Affairs (EOEEA) Massachusetts Environmental Policy Act Office (MEPA). Taken individually, the majority of the Projects, comprising of 13 building/space, 7 site/landscape, and 5 facility/ utility scale improvement projects, do not require MEPA review as most of the Project sites are confined to infill areas on campus that are currently or have been …

Investigating The Correlation Between Freeway Service Levels And Freeway Service Patrol Assists, Nora Chin Sep 2015

Investigating The Correlation Between Freeway Service Levels And Freeway Service Patrol Assists, Nora Chin

Master's Theses

The Bay Area Metropolitan Transportation Commission’s (MTC) Freeway Service Patrol’s highway motorist response service is reporting a reduction in their service levels. We analyze the relationship between the reduction in the Bay Area Freeway Service Patrol’s (FSP) motorist assists and changes in vehicle miles traveled (VMT), California Highway Patrol (CHP) reported incidents, and cover research on the impact of new and old vehicle fleet turnover. VMT and CHP incidents have differential effects on FSP assists. Although incidents occurring on freeways with high traffic flows tend to cause more congestion, the trend in local VMT along Bay Area freeway corridors does …

Using Archived Transit Data To Analyze The Effect Of Rainfall On Transit Performance Measures At The Route Level, Nicholas F. Bleich Jun 2015

Using Archived Transit Data To Analyze The Effect Of Rainfall On Transit Performance Measures At The Route Level, Nicholas F. Bleich

Master's Theses

This study investigates the effect of rainfall on transit performance measures at the route level in the Puget Sound region of Washington State. Transit agencies are required to report certain performance metrics to the Federal Transit Administration (FTA), but performance measures can also be used to evaluate service and provide customers with information regarding the transit system. Using a three-year sample of archived automatic vehicle location (AVL) and hydrologic data the relationships between ridership, travel time, delay, and rainfall were investigated. The analysis of daily ridership and rainfall resulted in no statistically significant results, however, the results are supported by …

Measuring The Influence That Components Have On Pedestrian Route Choice In Activated Alleys, Samuel Hirsher Gross Jun 2015

Measuring The Influence That Components Have On Pedestrian Route Choice In Activated Alleys, Samuel Hirsher Gross

Master's Theses

This paper explores how cities have integrated formal planning into improving public space. Through a review of literature on the topic, this the paper identifies the potential design has to renovate narrow streets and alleys, within the public right of way. By preforming an assessment of plans and programs, this paper identifies the common themes or components that have been used by planners, architects, and engineers to improve the urban environment for pedestrians. Based on this information, a pilot study was created to measure the influence the most common components have on pedestrian route choice. The results are then compared …

A Guide For Planning A Bike Share System At The University Of Nebraska-Lincoln, Wade M. Schuldt May 2015

A Guide For Planning A Bike Share System At The University Of Nebraska-Lincoln, Wade M. Schuldt

Community and Regional Planning Program: Theses and Student Projects

The purpose of this document is to serve as a framework for planning a bicycle share system at the University of Nebraska-Lincoln, with the possible inclusion of the City of Lincoln, Nebraska, in the system. This document provides a background review of the evolution of bike share systems and the recent rapid growth of these systems around the world. The document describes planning methodologies used in other locations and the lessons learned from the bike share systems around the world, as to what processes should be pursued to implement a successful bike share system. With the University of Nebraska-Lincoln move …

Love Is A Two Way Street, William W. Riggs, John Gilderbloom May 2015

Love Is A Two Way Street, William W. Riggs, John Gilderbloom

William W. Riggs

A half a century ago, we were in love with our streets. They were also living things. They were the open-air living room of our society, the conduct for neighborhood play and discussion, the glue of our social fabric. One of the key urban theorists of the 20th century, Jane Jacobs wrote in Fortune Magazine that the street “…works harder than any other part of downtown. It is the nervous system; it communicates the flavor, the feel, the sights. It is the major point of transaction and communication. Users of downtown know very well that downtown needs not fewer streets, …

Low Income, Supermarket Accessibility, And The Transportation Network: A Multimodal Analysis Identifying Areas Of Poor Accessibility And Intervention Strategies In Indianapolis, Indiana, Andrea Leigh Bailey Apr 2015

Low Income, Supermarket Accessibility, And The Transportation Network: A Multimodal Analysis Identifying Areas Of Poor Accessibility And Intervention Strategies In Indianapolis, Indiana, Andrea Leigh Bailey

Open Access Theses

The United States Department of Agriculture (USDA) Economic Research Service estimates that 23.5 million people live in food deserts, over half of which are considered low-income residents. Accurately defining a food desert is crucial as the designated areas can benefit from grant opportunities and funding priority. To qualify as an urban food desert, the USDA requires that at least 500 residents or one-third of the population live outside a one-mile buffer from a supermarket as well as have a median income of less than 80% of the area average or a poverty rate of greater than 20%. Approaches in the …

Accounting For The Short Term Substitution Effects Of Walking And Cycling In Sustainable Transportation, Daniel P. Piatkowski, Kevin J. Krizek, Susan L. Handy Jan 2015

Accounting For The Short Term Substitution Effects Of Walking And Cycling In Sustainable Transportation, Daniel P. Piatkowski, Kevin J. Krizek, Susan L. Handy

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The environmental benefits of bicycling and walking depend on the degree to which their use substitutes for car driving. Assuming that every walking and bicycling trip replaces a driving trip is likely to produce overestimates of the potential for such modes to reduce vehicle travel and city-scale greenhouse gas emissions. Measuring this ‘‘substitution effect’’ is not straightforward. There are many dimensions of the substitution effect, including trip type, substituting mode, extent, time horizon, and activity patterns. Previously used approaches to measure substitution include indirect inference and direct questioning. This study piloted an intercept survey using the direct questioning approach at …
