Biography

Dr Caulfield joined the Department of Civil, Structural and Environmental Engineering in 2008. Since joining the Department Dr Caulfield has embarked on an intensive research program addressing global issues such as the environmental impacts of transport and methods to reduce the carbon impacts of transport and in 2017 he addressed the Irish Citizens Assembly on this topic. He is currently advising the Climate Change Advisory Council on pathways to decreasing transport emissions by 2030. Dr Caulfield has published over 150 papers in these areas in high impact international journals and international conferences and to date has been awarded aprox. 2.2 million in research funding (from EPA, SFI, FP7, CEDR, NRA, DTTAS and RSA). He currently has 4 PhD students and 3 postdoctoral researchers in his research group. Dr Caulfield also a member of a number of National and International research groups and is the former Chair of the Irish Transportation Research Network and sits on the executive committee of the Universities Transport Studies Group as well as several committees at the Transportation Research Board in Washington D.C. He is an Associate Editor of Renewable & Sustainable Energy Reviews (impact factor: 11.239) and is a member of the International Editorial Board of Transportation Research Part D: Transport and Environment (impact factor: 4.412), Case Studies on Transport Policy (impact factor: 1.580), Transport Policy (impact factor: 3.430) and the Journal of Transport Geography (impact factor: 4.473). Dr Caulfield coordinates the SS Civil Engineering year and is the School of Engineering coordinator of the SS year industrial placement.

Project Title

Smart Mobility Initiative for Lower Emissions (SMILE)

From

Summary

The vision of this project is that achieving the change required is possible if we stop working in the isolation of our disciplines and combine our expertise around a rich understanding of the transport ecosystem. The epicentre of this ecosystem is the individual trip decision - we need to understand this decision process from all angles. SMILE brings together multidisciplinary expertise from Computer Science, Engineering and Social Sciences to design an evidence-based mobility ecosystem centred on a trip decision-making app. The app will: - Inform, educate and motivate users towards low- or no-emissions modes with a user-friendly interface making accessing eco-modes seamless - Personalisation will enable trip guidance to be optimised to the user, sensors will harvest actual mobility behaviour and machine learning will optimise the nature and presentation of choices to maximise eco-mode choices. - These data can be used to inform transport services and infrastructure planning and policy

DiSTRaCT: moDal ShifT Reduce Carbon in Transport

From

Jan 2019

Jan 2020

Summary

Much attention has been focused on the transport sector and how to reduce emissions and energy consumption in this field. Traditionally much of the focus has been on building new infrastructure and investment in public transport, walking and cycling. Little attention has been paid to changing underlying transport behaviours and trying to understand why we travel in the ways we do. The DiSTRaCT project aims to examine this under researched are in Ireland and cast a wide net to look for low cost behavioural change projects that have been successful internationally and determine if they could be successful in Ireland. A key element of the DiSTRaCT project will be to produce new methods to evaluate the potential success of behavioural change projects and supplement the work being conducted on the economic evaluation of transport projects. The final deliverable of the project will be a list of potential pilot projects that could be launched in Ireland and how to leverage the greatest return on any potential pilot projects.

An evaluation into the safety of cycling in Dublin city and measures to reduce risk to cyclist

From

2017

2021

Summary

The research proposes to evaluate the safety of cycling in Dublin city, and is based upon findings from research previously undertaken using RSA historical cyclist collision data for years 2006 to 2012. Cyclist collisions hot spot areas in Dublin city were identified using kernel density estimation, a spatial statistical tool available in ArcGIS 10.3 that enabled the spatial pattern of collision points to be visualised as clustered hot spots areas. The resultant maps revealed cyclist collisions occurred more frequently at cross roads and T junctions where there were discontinuations in the road network requiring cyclist to stop or reduce speed. Areas with a high concentration of collisions were located in the centre of the city along the quays of the river Liffey, Temple bar area and Dame Street. This was followed by the Grand Canal to the south side of the city, in particular, Rathmines Bridge, Ranelagh Bridge and also Harold's Cross Bridge. Another key finding showed that circa 58% of collisions occurred on roads with on street cycle lanes and that circa 80% of cyclist collisions were with a small motorised vehicle (i.e. car, taxi or van). Focus was therefore further placed on collisions between small motorised vehicle and pedal cyclist in relation to the safety of roads with on street cycle lanes as preliminary results had identified these to be major contributors for all cycle collisions during the study period. The overall aim of this research is to develop a new methodology to reduce numbers of cyclist collisions in cities and improve safety for cyclist by identifying and evaluating areas with a high incidence of cyclist collisions from which preventative measures as adopted internationally will be recommended in order to reduce the risk of collisions for cyclists and consequently improve road safety for cyclist. For the purpose of this research Dublin City will be used to develop this methodology. Secondary to this is to examine how and why cyclist collisions are reported and examine alternative ways of reporting in a way that they can be easily integrated into a GIS and used for subsequent analysis.

Current Status and Potential Role of Eco Labels in Informing Environmentally Friendly Purchases and Behaviours

From

2016

2017

Summary

Eco labels are a widely used method of communicating environmental information to consumers in the hopes that they will be encouraged to pick the most sustainable option available. Eco labels are used in a wide range of industries, and are even required by legislation in some, however, little research exists regarding their effectiveness in terms of promoting sustainable consumption. This research aims to use a number methods to examine the role of eco labels in the Irish market and provide recommendations for future designs and implementations. Specifically this will comprise of an assessment of current eco labels and an econometric examination of the role that eco labels can play in purchases. The most novel aspect of this research will utilize emerging eyetracker technology to gain an understanding of how eco labels compete with other types of product information for consumers' attention. This will also examine the relative effectiveness of existing methods of communicating environmental information.

Greening Transport

From

2014

2018

Summary

The main vision of the Greening Transport project is to merge the technical evaluation of the emissions from transport, and the improvements in their calculation, with the behavioural changes needed to realise these reductions in emissions. Past attempts to measure the "low hanging fruit" in terms of emissions reductions from transport have failed to fully merge these two disciplines. The project team believe that in order for the EPA to have a holistic picture of the potential emission reductions that are possible in Ireland by 2030 (and beyond), it is vital not to ignore the behavioural constraints in which transport analysis is framed. While it is possible to predict targets for take up using assumptions, to ignore human behaviour is to not fully grasp the problem at hand. With this in mind the work packages for this project have been designed to tackle the technical emissions and transportation modelling, as well as the application of behavioural constraints to these models to provide the EPA with details of what emission reductions are possible based upon the current research.
