Keys To Successful Balanced Scorecard Implementation And Use Based On Published Implementation Attempts, Aarom J. Hepler, Bradley E. Anderson, Martha C. Cooper, Jeffrey A. Ogden

Journal of Transportation Management

In recent years many companies have evolved from being centrally located and managed to decentralized, multi-national companies consisting of many separate entities to be strategically managed. In response to this and other changes, such as the need for better measurement of performance, a strategic management tool was developed called the Balanced Scorecard (BSC). This research provides a tool to guide and evaluate BSC implementation. A meta-synthesis approach was used to examine qualitative BSC data available in the literature that suggested eleven keys to successful BSC implementation and use. These keys are then used to benchmark an implementation in a government …

Robust Repositioning To Counter Unpredictable Demand In Bike Sharing Systems, Supriyo Ghosh, Michael Trick, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Bike Sharing Systems (BSSs) experience a significant loss in customer demand due to starvation (empty base stations precluding bike pickup) or congestion (full base stations precluding bike return). Therefore, BSSs operators reposition bikes between stations with the help of carrier vehicles. Due to unpredictable and dynamically changing nature of the demand, myopic reasoning typically provides a below par performance. We propose an online and robust repositioning approach to minimise the loss in customer demand while considering the possible uncertainty in future demand. Specifically, we develop a scenario generation approach based on an iterative two player game to compute a strategy …

Independent Study Project (ISP) Collection

As the urban population continues to increase rapidly in Dar es Salaam it will become increasingly important to find sustainable means of urban transportation. With planned infrastructure improvements in the city to help alleviate traffic congestion, bicycles, which represent a largely underutilized form of urban transportation, have the potential to play a large role in the future of the city. Through background research, direct observations, community surveys, and interviews, both formal and informal, this study sought to understand the impact of the recent addition of bike lanes along the first phase of the Dar Bus Rapid Transit line. It was …

Methodologies For Estimating Traffic Flow On Freeways Using Probe Vehicle Trajectory Data, Khairul Azfi Anuar

Civil & Environmental Engineering Theses & Dissertations

Probe vehicle data are increasingly becoming the primary source of traffic data. As probe vehicle data become more widespread, it is imperative that methods are developed so that traffic state estimators such as flow, density, and speed can be derived from such data. In this dissertation three different methodologies are proposed for predicting traffic flow or volume on a freeway. All of the proposed methodologies exploit several different traffic flow theories in conjunction with probe vehicle data to predict traffic flow. The first methodology takes advantage of the fundamental diagram or speed-flow relationship. The relationship states that flow can be …

Effects Of Visibility And Alarm Modality On Workload, Trust In Automation, Situation Awareness, And Driver Performance, Smruti J. Shah

Psychology Theses & Dissertations

Driving demands sustained driver attention. This attentional demand increases with decreasing field visibility. In the past researchers have explored and investigated how collision avoidance warning systems (CAWS) help improve driving performance. The goal of the present study is to determine whether auditory or tactile CAWS have a greater effect on driver performance, perceived workload, system trust, and situation awareness (SA). Sixty-three undergraduate students from Old Dominion University participated in this study. Participants were asked to complete two simulated driving sessions along with Motion Sickness Susceptibility Questionnaire, Background Information Questionnaire, Trust Questionnaire, NASA Task Load Index Questionnaire, Situation Awareness Rating Technique …

Magnopark, Smart Parking Detection Based On Cellphone Magnetic Sensor, Maryam Arab

Computer Science Theses & Dissertations

We introduce a solution that uses the availability of heavy crowds and their smart devices, to gain more result as to where potential parking is possible. By leveraging the raw magnetometer, gyroscope, and accelerometer data, we are able to detect parking spots through the natural movement exerted by the walking pedestrians on the sidewalks beside the streets. Dating back as far as 2013, a very large portion of pedestrians composing the crowds on the sidewalk, possessed at least one smart device in their hand or pocket14]. It is this statistic that fuels our application, in which we depend on crowds …

Bakken Bombs: A Criminological Inquiry Into The Lynchburg Train Derailment, Travis W. Milburn

Sociology & Criminal Justice Theses & Dissertations

In recent years, several significant train derailments involving the transportation of crude oil have dotted the North American landscape. Each resulted in environmental and social harm to some degree which was extensive in many instances. Oil train derailments have occurred in places such as Lac-Mégantic, Canada (July 2013), Casselton, North Dakota (December 2013 and November 2014), and Mount Carbon, West Virginia (February 2015). Following derailments, communities have faced substantial environmental damage, human death and injury, and overall disruption from the explosions and subsequent oil spills that characterize these events. This project specifically examined the April 30, 2014 derailment in Lynchburg, …

Webinar: States On The Hot Seat: State Efforts To Reduce Greenhouse Gas Emissions From Transportation, Rebecca Lewis

TREC Webinar Series

Transportation accounts for approximately 33 percent of greenhouse gas (GHG) emissions in the United States. While the federal government issued notice of a proposed rule that would include a GHG reduction performance measure for the first time, over the past decade, several innovative states have offered leadership on policies aimed at reducing GHG through transportation.

A recent project examines innovative policies in four such states: California, Maryland, Oregon and Washington. This webinar will:

• Highlight policy approaches for reducing GHG from transportation,
• Offer an assessment of strengths and weaknesses of various policy approaches, and

The Cycling Gender Gap: What Can We Learn From Girls?, Jennifer Dill

PSU Transportation Seminars

In the U.S., women are far less likely to bicycle for transportation than men. Explanations include, among others, safety concerns (traffic and crime), complex travel patterns related to household responsibilities, time constraints, lack of facilities that feel safe, and attitudes. This talk will explore how this gender gap emerges in childhood, using data from the Family Activity Study. The study collected data from 300 Portland families (parents and children) over two years, allowing us to see how things change over time.

On Both Sides Of The Tracks: Light Rail And Gentrification In Portland, Oregon, Nathan Eric Rochester

Dissertations and Theses

This study draws on census data and geographic information systems (GIS) to investigate the relationship between light rail transit (LRT) infrastructure development and gentrification in Portland, Oregon. While recent research using comprehensive measures of neighborhood socioeconomic status (SES) supports a potentially causal link between transit development and gentrification, research into the effects of transit on property values alone tends to dominate the discourse. This study therefore seeks to build on previous research to develop an index measure of neighborhood SES and SES change based on measures of education, occupation, and income, using census data from 1980-2010. This multifaceted measure of …

Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Bike sharing can play a role in providing access to transit stations and then to final destinations, but early implementation of these systems in North America has been opportunistic rather than strategic. This study evaluates local intermodal plan goals using trip data and associated infrastructure such as transit stops and bike share station locations in Austin, Texas, and Chicago, Illinois. Bike sharing use data from both cities suggest a weak relationship with existing rail stations that could be strengthened through collaborative, intermodal planning. The study suggests a planning framework and example language that could be tailored to help address the …

Transforming Bus Service Planning Using Integrated Electronic Data Sources At Nyc Transit, Jeffrey Hanft, Shrisan Iyer, Brian Levine, Alla Reddy

Journal of Public Transportation

The installation of an Automatic Vehicle Location (AVL) system alongside existing Automated Fare Collection (AFC) data spurred development of an inferred bus boarding and alighting ridership model at New York City Transit (NYCT), allowing for 100% passenger origin-destination (O-D) data citywide. Analysis techniques that relied primarily on professional judgment due to lack of data were replaced by more sophisticated statistical techniques. This paper describes two case studies and the resulting service planning potential from having access to fully-integrated big data sources: a neighborhood-wide analysis of performance and ridership, where 100% data allowed planners to pinpoint specific, low-cost reroutes and stop …

Connecting People To Places: Spatiotemporal Analysis Of Transit Supply Using Travel-Time Cubes, Steven Farber

TREC Final Reports

Despite its importance, temporal measures of accessibility are rarely used in transit research or practice. This is primarily due to the inherent difficulty and complexity in computing time-based accessibility metrics. Estimating origin-to-destination travel times that include the “last mile” of travel between the transit network and actual start and endpoints of the trip is technically difficult. Not only do such estimations require multimodal network structures, they also require detailed knowledge of transit schedules and sophisticated algorithms for calculating shortest paths using such inputs. Recently, new standards for sharing transit schedules and geographic data, namely the General Transit Feed Specification (GTFS) …

The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo

Dissertations and Theses

Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form …
