Do transportation investments, particularly rail transit investments, facilitate long-term city and regional economic growth? If yes, what is the signficiance of the role of rail transit, versus other factors, in regional economic growth? In this webinar Bill Lee, Executive Vice President of AECOM Economics, will provide an extensive data-based review of three city pairs, each representing two cities that once had similar profile, but with one city that invested in regional rail transit and the other that did not. Data that was used in this analysis included historical office construction data for comparable central business districts. The three city pairs that will be discussed include: San Francisco, California and Los Angeles, California (1970 -1990), Portland, Oregon and Memphis, Tennessee (1980 – 2000), and San Diego, California and St. Petersburg, Florida (1980 – 2000).
