Since 2001, Deloitte Access Economics has routinely screened government budgets, announcements by private companies, the media, and other publicly available data sources to produce a quarterly snapshot of expected investment plans for each sector, including transport. We have linked the quarterly releases of the Investment Monitor from Q1 2001 to Q1 2020 to form a panel dataset that tracks the expected cost and degree of commitment to all publicly announced investment projects from first announcement through to completion.
