Sustainable Transport Appraisal: A Literature Review and Implications for Policy Makers

by Yeonjung Songa, Warren Whitneya, Wen Zhang, Barry Colleary, Brian Caulfield, Juan Martinez-Covarrubias
National Transport Authority, Dublin, Ireland
Trinity College Dublin, Dublin, Ireland
Kobe University, Kobe, Japan
American University, Washington, United States

The study addresses concerns about the compatibility of current transport appraisal methods with sustainability goals, highlighting the need for modal shift towards sustainable transport. It discusses how traditional methods like Cost-Benefit Analysis (CBA) may not align with sustainable policy goals and explores the challenges of employing Multi-Criteria Analysis (MCA) to account for non-monetary benefits. Through a literature review and analysis of Ireland’s appraisal framework, the study aims to identify improvements needed for transport appraisal to align with sustainability policies.

Investigate the rural mobility and accessibility challenges of Seniors

by Tom Ryan, National Transport Authority

The paper investigates rural mobility challenges for seniors, projecting a significant demographic shift over the next twenty years in Ireland. Utilizing the PESTEL framework and qualitative interviews with stakeholders, it highlights issues such as lack of transport access to healthcare facilities and the potential of Mobility as a Service (MaaS) to alleviate rural transport poverty. The study suggests short-, medium-, and long-term recommendations to ensure rural public transport meets the needs of future generations in Ireland.

Enhanced Demand Forecasting & Digitalization

by Kevin Cox and Deborah John

The paper discusses Ireland’s National Transport Authority’s utilization of web-based technology in collaboration with all 31 Irish Local Authorities to reassess and improve population and employment datasets for the National Transport Model, aiming to enhance the accuracy and consistency of data inputs for evidence-based decisions on strategic planning and sustainable development goals.
