In TII-STP/pagglomR: Calculating the Agglomeration Impacts of Transport Projects

pagglomR

A package for calculating the agglomeration impacts of transport projects in Ireland.

This package is developed in the R programming language and requires an installation of R. R can be downloaded from https://cran.r-project.org/. We would recommend the use of the RStudio IDE when using R.

To install this package in R use the command remotes::install_github("TII-STP/pagglomR"). This will install the development version. A stable version will be uploaded to CRAN in due course.

Information

The pagglomR package has been developed for use on national roads projects in line with the TII Project Appraisal Guidelines (PAG). It is a flexible tool that can also be used for public transport and multi-modal assessments.

For further information on the transport modelling analysis required to develop the necessary inputs for the pagglomR package, refer to PAG Unit 6.9 - Wider Impacts. To see examples on how to use the pagglomR package, go to the 'Articles' section of the package website https://tii-stp.github.io/pagglomR/.

The relevant economic parameters built into the pagglomR package are taken from the DPER Public Spending Code (2019), the DoT Common Appraisal Framework for Transport Projects and Programmes (2016) and TII PAG Unit 6.11 - National Parameter Values Sheet (2021).

Key requirements

This package relies on outputs from a transport model in the form of demand and cost skims from "without scheme" / "Do Minimum" and "with scheme" / "Do Something" scenarios.
