This study assesses the overall impact of job creation associated with the anticipated construction of a high-speed rail (HSR) network in the United States, particularly in California, which was scheduled to begin construction as early as September 2012. Using variations of a bottom-up construction estimation technique, the study provides estimates of the quantity and type of workers needed during the design, construction, and operation of high-speed rail infrastructure, as well as education and training needs and level of this forecasted workforce. Given the high profile of state and national commitment to HSR initiatives, as well as its potential opportunity to generate employment, a comprehensive analysis that discusses the education, training, and attendant needs produced during the creation of HSR networks is timely. By using a refined bottom-up approach to estimate labor, education, and training needs required for the California HSR network, and with general application of this model across assessment of other corridors, this report seeks to identify the magnitude of workforce development challenges that lie ahead in the implementation of national HSR systems.

There have been growing concerns around the world over the rising spatial inequality (SI) amid fast and vast globalization. This paper presents an effort to benchmark the conditions and trends of spatial inequality in 37 megaregions in the United States, Europe, and China. Furthermore, the study selected three megaregion examples and analyzed the effect of developing high-speed rail (HSR) as an infrastructure investment strategy on reshaping the spatial pattern of job accessibility. The study measures spatial inequality with the Theil index of gross regional product and with the rank-size coefficient of polycentricity. Results show that spatial inequality exists and varies in magnitude within and between megaregions. On average, Chinese megaregions exhibited the level of spatial inequality about two times or more of those in the U.S. and European megaregions. The decade between 2006 and 2016 saw a decrease in the Theil index measure of megaregional inequality in China, but a slight increase in the United States and Europe. Fast growing megaregions exhibit high levels and rising trends of spatial inequality regardless of the country or continent setting. HSR helps improve mobility and accessibility; yet the extent to which HSR reduces spatial inequality is context dependent. This study presents a first attempt to assess and compare the spatial inequality conditions and trajectories in world megaregions aiming at promoting international learning.
