Assessing total costs and benefits of sustainable transport policy in ireland
O'MAHONY, MARGARET MARY; CAULFIELD, BRIAN (2010)The objective of this paper is to assess the benefits of greenhouse gas (GHG) and air pollutant emission reductions projected by current Irish sustainable transport policy and to compare the Business as Usual (BAU) ... -
Design and manufacture of surface acoustic wave sensors for real-time weigh-in-motion.
GERAGHTY, THOMAS DERMOT; O'MAHONY, MARGARET MARY (IEEE, 2005)This paper presents the design and manufacture of surface acoustic wave (SAW) strain sensors which can be produced in a university environment. These sensors can be interrogated wirelessly and operated without a power ... -
Design of feeder route network using combined genetic algorithm and specialised repair heuristic
O'MAHONY, MARGARET MARY (National Center for Transit Research (NCTR), 2007)In metropolitan cities an efficient integrated public transportation system is unavoidable in order to restrict unsustainable growth of private and intermediate transport modes. Well designed feeder routes and ... -
Environmental and social transport costs: a case study of Ireland
O'MAHONY, MARGARET MARY (Transportation Research Board of the National Academies, 2005)The aim of the EU funded UNITE research project was to provide information about the costs, benefits and revenues of all transport modes including environmental and social costs. The project involved compiling accounts ... -
Evaluation of Luas system using transit capacity and quality of service manual
O'MAHONY, MARGARET MARY; Rogers, P (Transportation Research Board, 2006) -
An examination of the public transport information requirements of users
CAULFIELD, BRIAN; O'MAHONY, MARGARET MARY (IEEE Intelligent Transportation Systems Society, 2007)This paper focuses on the provision of public transport information in Dublin, Ireland. It examines both existing and potential methods of accessing information, with particular focus on the implementation of various ... -
Examining the Factors that Impact upon Public Transport Commuting Stress
O'MAHONY, MARGARET MARY (University of South Florida, 2009)The first objective of this research was to examine the level of stress caused by commuting into Dublin city centre. The second objective was to determine the value placed on the comfort and reliability of public transport ... -
Factors influencing preferences for real-time public transport information
CAULFIELD, BRIAN; O'MAHONY, MARGARET MARY (Association for European Transport, 2007)This paper presents the results of a study undertaken in Dublin, to ascertain preferences for real-time public transport information. This study examines the need for public transport information across three stages of ... -
Measuring network reliability by considering paradoxes
O'MAHONY, MARGARET MARY (National Academy of Sciences, 2009)Traditionally, game theoretic approaches to measuring transport network reliability have relied on the outcome of a game played between network users seeking to minimize their travel costs and an OD-specific demon that ... -
Measuring network reliability considering paradoxes: multiple network demon approach
O'MAHONY, MARGARET MARY; O'MAHONY, MARGARET MARY (Transportation Research Board, 2009)Traditionally, game theoretic approaches to measuring transport network reliability have relied on the outcome of a game played between network users seeking to minimize their travel costs and an OD-specific demon that ... -
Measuring risk of attack on bus networks
O'MAHONY, MARGARET MARY (2008)Public transport systems are at risk from attacks as they are open, dynamic systems carrying large numbers of people. Although attacks have been carried out on public transport since the 1920?s, the nature of attacks has ... -
Mixed stochastic user equilibrium behavior under traveler information provision services with heterogeneous multiclass multicriteria decision making
O'MAHONY, MARGARET MARY (Taylor and Francis, 2009)This paper studies travellers? mixed stochastic user equilibrium (SUE) behaviour under traveller information provision services with heterogeneous multi-class multi-criteria decision making. A multi-class, multi-criteria ... -
A model for development of optimised feeder routes and coordinated schedules: a genetic algorithms approach
O'MAHONY, MARGARET MARY (Elsevier, 2006)Many attempts have been made to solve bus route network design problems by splitting it in two stages, one for routing and the other for scheduling. Some researchers have made attempts to solve network design problems ... -
Parallel implementation of a transport network model
O'MAHONY, MARGARET MARY (Elsevier, 2005)This paper describes the parallel implementation of a transport network model. A `Single-Program, Multiple Data? (SPMD) paradigm is employed using a simple data decomposition approach where each processor runs the same ... -
The provision of on street passenger information via real time passenger information; a case study of Dublin
CAULFIELD, BRIAN; O'MAHONY, MARGARET MARY (IEE,, 2004)In June 2001 Dublin Bus introduced a real time passenger information (RTPI) system on the first of its eleven quality bus corridors (QBC), on the Lucan QBC. The introduction is part of a three-year pilot programme called ... -
Rail passengers' preferences for onboard Wi-Fi internet access
O'MAHONY, MARGARET MARY (2009)This paper presents the results of a survey which was conducted on an Irish Rail service to ascertain how the value of travel time may change if individuals could partake in another activity while travelling. The survey ... -
The relationship between geometric design consistency and safety on rural single carriageways
O'MAHONY, MARGARET MARY (Association for European Transport, 2007)Rural single carriageways in Ireland tend to fall below current design standards and have higher accidents rates (per vehicle kilometre) than roads designed to modern standards. Resources are not available to improve ... -
A stated preference analysis of real-time public transit stop information
CAULFIELD, BRIAN; O'MAHONY, MARGARET MARY (2009)This paper presents the results of a study conducted to examine the benefits derived from real-time public transit stop information. This research examines the preferences between several options of receiving real-time ... -
Time-dependent road network design frameworks with land use consideration: policy implications
O'MAHONY, MARGARET MARY (2008)In the past, transport network design focused on the effect of designs on the transport system alone but not on the land use system, and ignored the land use-transport interaction over time. This may result in obtaining ... -
Tracing individual public transport customers from an anonymous transaction database
LYONS, DONAL FRANCIS; O'MAHONY, MARGARET MARY (University of South Florida, National Center for Transit Research, 2006)Data mining concepts are used frequently throughout the transportation research sector. This paper uses the concept of the market basket technique on public transport users as a means of gaining more insight into their ...
