Analyzing the Effects of Weather on Light Rail Transit Performance in Dublin, Ireland
O'Mahony, Margaret; Walsh, Gearoid (2022)As climate change and greenhouse gas emissions receive increasing levels of attention, the need for sustainable transport solutions becomes increasingly apparent. The Luas is Dublin’s Light Rail Transit (LRT) network and, ... -
Awareness of health impacts of NO2 and, potential responses to diesel vehicle bans and proposals to cease their production
O'Mahony, Margaret; Broderick, Brian (2019)Evidence of associations between ambient concentrations of NO2 and a range of effects on health has strengthened in recent years. On average, transport is responsible for 40% of NOx emissions influencing ambient NO2 ... -
Barriers to Sustainable Transport in Ireland
Caulfield, Brian; O'Mahony, Margaret; Browne, David (Environmental Protection Agency, 2011)This synthesis report provides an overview of the findings from the Assessing the Barriers to SustainableTransport in Ireland project and distils the conclusions outlined in the End of Project Report. The purpose of this ... -
Dealing with latency effects in travel time prediction on motorways
O'Mahony, Margaret (2020)Real-time traffic information is now a crucial part of operating a road network. The quality, accuracy and reliability of such information is critical to the road operators and users. Real-time travel time prediction methods ... -
Electric Vehicle Household Charging Behaviour in Ireland and Aims for a Carbon Neutral Electric Fleet by 2020
O'Mahony, Margaret; Morrissey, Patrick (2015) -
Impact of Nitrogen Dioxide on Health with Particular Emphasis on Vulnerable Groups
O'Mahony, Margaret; Broderick, Brian; Hennessy, Martina (Environmental Protection Agency, 2023)Nitrogen dioxide (NO2) is a highly reactive gas and is primarily produced by the burning of fuel. It forms from emissions from cars, trucks and buses and power plants. Exposure to NO2 has been associated with adverse ... -
Informing the Strategic Rollout of Fast Electric Vehicle Charging Networks with User Charging Behaviour Data Analysis
O'Mahony, Margaret; Morrissey, Patrick (2016)With the current range limitations of existing electric vehicle ( EV ) technology, range anxiety has been identified as one of the main barriers to their adoption. For countries or states which are ... -
Integrated transportation and land use regression modelling for nitrogen dioxide mitigation
O'Mahony, Margaret; Broderick, Brian (2023)The transport sector has been identified as one of the main contributors to nitrogen dioxide (NO2) pollution in Ireland. This research develops an enhanced Wind Sector Land Use Regression (WS-LUR) model to estimate NO2 ... -
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
O'Mahony, Margaret; Mc Garrigle, Christine (2019)Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ... -
Local NO2 concentrations and asthma among over-50s in Ireland: A microdata analysis
O'Mahony, Margaret (2021)Background: Links between air pollution and asthma are less well established for older adults than some younger groups. Nitrogen dioxide (NO2) concentrations are widely used as an indicator of transport-related air pollution, ... -
Micro-Analysis of the Fueling Costs of Electric Vehicles in Consideration of the Range of Options Available to Electric Vehicle Users
O'Mahony, Margaret (2019)It is common knowledge that the costs of powering electric vehicles (EV) are less than the fuelling costs of internal combustion engine vehicles (ICEV) due to the relative per-unit prices of electricity and gasoline, ... -
Multivariate Short-term Traffic Flow Forecasting Using Time-Series Analysis
O'Mahony, Margaret; Ghosh, Bidisha (2009) -
Optimising shared electric mobility hubs: Insights from performance analysis and factors influencing riding demand
Caulfield, Brian; O'Mahony, Margaret; Hosseini, Seyedkeyvan; Stefaniec, Agnieszka (2023)In order to decarbonise the transport networks, systemic change is needed. One manifestation of this transformation is shared electric mobility, seeking to curtail car usage and ownership. This current case study aims to ... -
The Relative Influence of Proximity to Fast Road Infrastructure, Accessibility and Deprivation on Crime
O'Mahony, Margaret (Hindawi, 2018)Irish rural areas saw an increase in the number of burglaries in the period following the completion of a network of high speed motorway interurban routes. To test the hypothesis that the new fast infrastructure was ... -
Transport Sector Impacts of a Border between Ireland and Northern Ireland after a Hard Brexit
O'Mahony, Margaret; Morchid, Khaoula (2019)More than half of British voters chose to leave the European Union (EU) leading to a series of negotiations between the United Kingdom and the EU. The withdrawal of the UK from the EU is widely referred to as Brexit. As ... -
Using Automatic Vehicle Location System Data to Assess Impacts of Weather on Bus Journey Times for Different Bus Route Types
O'Mahony, Margaret (2021)Weather has the largest collective effect on transport systems, affecting users of all modes at the same time over a wide area. The aim of the research is to use Automatic Vehicle Location System (AVLS) data to investigate ...
