Modeling Intrazonal Distance and Duration in Addressing Limitation of Intrazonal Generalized Cost Commonly Applied in Transport Models
by Journal of Transportation Engineering, Part A: Systems
In this study, the intrazonal GC that was developed in the National Transport Authority’s (NTA) regional modelling system using a conventional fixed-fraction method (base) was compared to intrazonal GCs for six travel modes [passenger cars, bus, cycle, walk, taxi (passenger) and light goods vehicles] that were estimated using zonal GC equations adopted from literature.

Estimating values of time from revealed preference data – European Transport Conference 2021

Values of time (VOTs), i.e. the trade-off ratios between travel time and travel cost, play a key role in the modelling and appraisal of transport schemes and policies.
As Hess et al. (2020) note, while the early VOT studies in the 1960s and 1970s were based on revealed preference (RP) data capturing mode choices observed in the real world, current standard practice in Northern Europe (including the UK) is for the analysis of simple time-cost trade-offs collected using stated preference (SP) data.
Forecasting the impact of the Planning, Land Use and Transport Outlook (PLUTO) Project – a 2040 Ireland case study

and National Transport Authority, Dublin, Ireland
In February 2018 the Irish Government unveiled a new National Planning Framework (NPF), which underpinned ‘Project Ireland 2040’ – a national development and capital investment plan to the year 2040. The chief aim of which is to mandate and direct planning and infrastructure investment decision making over coming two decades in order to cater for projected population growth of one million people in a balanced and sustainable manner.

Climate Action Plan: Phase 3 Modelling Executive Summary
by National Transport Authority, SYSTRA Limited, and Jacobs
This report provides an overview of the transport modelling undertaken to support/inform the deliberations in the development of the Climate Action Plan 2023.
Note: The modelling assumptions and measures described within this text are not agreed policy measures. While the modelling provides a high degree of specificity in terms of the impacts from a carbon emissions perspective, it does not provide detailed design of the specific interventions or policies involved.
CAP23 includes further actions in respect of progressing detailed policy development and scheme design.

Mode and Destination Choice Modelling
This paper outlines the estimation of model parameters, based upon the use of revealed preference observations from both the census derived POWSCAR dataset and the Authority’s National Household Travel Survey (NHTS), for the Eastern Region of Ireland.
We provide a comparison of model parameters estimated from travel survey and census data, across four commuting segments, highlighting the similarities and differences between the respective estimated parameters.
