Mechanisms For Arranging Ride Sharing And Fare Splitting For Last-Mile Travel Demands, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau May 2014

Mechanisms For Arranging Ride Sharing And Fare Splitting For Last-Mile Travel Demands, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

A great challenge of city planners is to provide efficient and effective connection service to travelers using public transportation system. This is commonly known as the last-mile problem and is critical in promoting the utilization of public transportation system. In this paper, we address the last-mile problem by considering a dynamic and demand-responsive mechanism for arranging ride sharing on a non-dedicated commercial fleet (such as taxis or passenger vans). Our approach has the benefits of being dynamic, flexible, and with low setup cost. A critical issue in such ride-sharing service is how riders should be grouped and serviced, and how …

Data collection of transportation metrics helps us get a clearer picture of the transportation system, and helps us make smarter choices when it comes to improving the existing system. The rapid emergence of interconnected mobile devices carried along by travelers opens up many possibilities for gathering data as they travel, and also to serve them relevant data …


Observability In Traffic Modeling: Eulerian And Lagrangian Coordinates, Sergio Contreras May 2014

Observability In Traffic Modeling: Eulerian And Lagrangian Coordinates, Sergio Contreras

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditionally, one of the ways traffic flow has been studied is by using the kinematic wave model. This model is studied in the Eulerian framework. Recently, the kinematic wave model has been transformed into Lagrangian coordinates. This model of traffic flow together with the concept of observability for linear time invariant discrete time systems is applied to study the observability of four sections of a freeway in both Eulerian and Lagrangian coordinates. A system with densities in four sections of a freeway is designed, and the observability of the system is studied with different situations for sensors. When the system …


Highway Routine Maintenance Cost Estimation For Nevada, Monika Hagood May 2014

Highway Routine Maintenance Cost Estimation For Nevada, Monika Hagood

UNLV Theses, Dissertations, Professional Papers, and Capstones

State highway agencies are obligated to maintain existing roads for the highway systems to work efficiently and with greater longevity. Every year NDOT is responsible for approximately 13,150 lane miles of existing infrastructure. With that in mind, resources need to be provided to maintain the highway system.

The purpose of this research was to estimate annual routine maintenance cost for several typical treatment methods of highways. Five prioritization categories of highways used by NDOT were considered. Linear regression models were developed that present the relationship between costs including total maintenance cost and five maintenance cost components: labor, equipment, materials, manpower …


Stress And Coping As A Function Of Experience Level In Collegiate Flight Students, Jennifer Kirschner, John Young, Richard Fanjoy Apr 2014

Stress And Coping As A Function Of Experience Level In Collegiate Flight Students, Jennifer Kirschner, John Young, Richard Fanjoy

Journal of Aviation Technology and Engineering

Aviation as an industry requires a high degree of precision at all times. Large amounts of stress have been known to decrease performance to undesirable levels. While stress reactions and the coping skills used after encountering stressful situations differ from person to person, generalities can be made by comparing differences between groups. A large number of pilot applicants receive initial training within a university flight program each year. In order to better understand the perceived stress level and the coping skills used by these students, the current research project administered a perceived stress test and a coping skills inventory to …

Transit Planning Practice In The Age Of Transit-Oriented Development, Ian Carlton Apr 2014

Transit Planning Practice In The Age Of Transit-Oriented Development, Ian Carlton

PSU Transportation Seminars

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 …

Investigating Surface Performance Trade-Offs Of Unimpeded Taxiways, Tiffany T. Le Apr 2014

Investigating Surface Performance Trade-Offs Of Unimpeded Taxiways, Tiffany T. Le

Open Access Theses

Optimizing usage of unimpeded taxiways is a near-term operational change to mitigate emission impact on aviation and increase efficiency at airports. An unimpeded taxiway is a path for an aircraft to taxi around an active runway. Unimpeded taxiways provide benefits such as increased departure throughput, increased safety, reduced surface congestion, more efficient taxi-in procedures, and thereby also yield environmental benefits. The goals of this work are to investigate the use of current taxiways, examine surface performance and fuel burn trade-offs, and to develop a decision-support model based on potential fuel savings of unimpeded taxiways. This study analyzes unimpeded taxiway use …


Detecting Air Traffic Controller Interventions In Recorded Air Transportation System Data, Yul Kwon Apr 2014

Detecting Air Traffic Controller Interventions In Recorded Air Transportation System Data, Yul Kwon

Open Access Theses

In this study, I propose a systematic method of detecting aircraft deviation due to air traffic controller (ATC) intervention. The aircraft deviations associated with ATC interventions are detected using a heuristic algorithm developed from analyzing the actual positions of an aircraft to its filed flight plan when the aircraft trajectories were identified as having an encounter in a loss-of-separation incident. An actual (closed-loop) flight trajectory of the Cleveland Air Route Traffic Control Center (ZOB ARTCC) was collected from the FlightAware database. This was compared with the corresponding planned (open-loop) trajectory dataset generated by the Microsoft© Flight Simulator X (FSX). I …

Distortions In The Measurement Of The Efficiency Of Financial Leverage Strategies In The Airline Industry When Operating Leases Are Ignored, Carl A. Sheraga, Paul Caster Apr 2014

Distortions In The Measurement Of The Efficiency Of Financial Leverage Strategies In The Airline Industry When Operating Leases Are Ignored, Carl A. Sheraga, Paul Caster

Journal of Transportation Management

The Financial Accounting Standards Board and the International Accounting Standards Board have set forth a proposal requiring companies to capitalize operating leases and include them as assets and liabilities on their balance sheets. The proposal is motivated by the fact that current methods accounting for operating leases hide a great deal of off-book leverage and thus are misleading to investors. Such a change would have a significant impact on the U.S. airline industry where aircraft and property operating leases are quite prevalent. This study utilizes an in-depth strategic management perspective in examining how well U.S. airlines pursue optimization strategies with …


The 6th Mode Of Transportation, Robert O. Walton Apr 2014

The 6th Mode Of Transportation, Robert O. Walton

Journal of Transportation Management

The five modes of freight transportation are normally characterized as motor carriers, railroads, airlines, water carriers, and pipelines. This paper will attempt to position the Internet as the sixth mode of transportation. This paper compares the strengths and weaknesses of the traditional five modes of transportation against the proposed 6th mode of the Internet. Without including the Internet as a mode of transportation, and tracking the economic value that it adds to the economy, the economic impact of the Internet as a mode is not considered. The recommendation of this study is that the Internet should be added to the …

Active Travel Co-Benefits Of Travel Demand Management Policies That Reduce Greenhouse Gas Emissions, Mti Report 12-12, Caroline Rodier, Richard W. Lee, Brandon Haydu, Nicholas J. Linesch Apr 2014

Active Travel Co-Benefits Of Travel Demand Management Policies That Reduce Greenhouse Gas Emissions, Mti Report 12-12, Caroline Rodier, Richard W. Lee, Brandon Haydu, Nicholas J. Linesch

Mineta Transportation Institute

There is increasing evidence that improved health outcomes may be significant co-benefits of land use plans and transport policies that increase active transport (or walking and biking for purposeful travel) and reduce greenhouse gas emissions (GHGs) from vehicle miles traveled (VMT). A greater understanding of these benefits may broaden the constituency for regional planning that supports local and national GHG reduction goals. In this study, California’s activity-based travel demand model (ABM) is applied to (1) demonstrate how this new generation of travel models can be used to produce the active travel data (age and sex distributions) required by comparative risk …

Aesthetically Designed Maps: Development And Perception, Catherine Wang Mar 2014

Aesthetically Designed Maps: Development And Perception, Catherine Wang

Graphic Communication

This research explored the creative element of subway map creation in light of its effectiveness. Printed subway maps, used often for metropolitan cities and areas, are limited in physical dimension and scale, carrying minimal information. The New York, San Francisco Bay Area, Tokyo, Paris, London and Moscow subway maps highlight similar design and abstraction that fulfill the basic necessary elements for subway patrons. Over the years since the first metro map for each city was created, maps have become more simplified by removing physical land features and reference points to make way for expanding and new subway lines, stations, and …
