| Abstract: | Many US cities aim to increase environmentally sustainable modes of transportation, such as cycling or public transit. However, the current built environment in many of these cities does not adequately support cyclists or public transit riders. Bicycle infrastructure can minimize cyclists’ exposure to high-speed automobile traffic and increase the actual and perceived safety of cycling. Bicycle infrastructure can also potentially improve connections to public transit stops and stations. However, planners lack the tools to effectively measure where bicycle infrastructure improvements will yield the best outcomes. New research from Georgia Tech addresses this problem by developing two new modeling tools, BikewaySim and TransitSim, to assess how bicycle infrastructure can affect cycling and public transit access. Using BikewaySim, the researchers modeled over 28, 000 potential cycling trips, calculating the impacts of two proposed cycling infrastructure projects in Atlanta, Georgia. Using TransitSim, the researchers modeled combined cycling and transit trips from four distinct locations in Atlanta, Georgia. This brief summarizes the findings from that research.

| Abstract: | Commuting is nearly ubiquitous across New England. Employers in cities and towns large and small depend on workers who commute from communities near and far. Communities, in turn, rely on employers located in cities and towns scattered in every direction to provide jobs for their residents. Workers may choose to live in a city other than where they work for a host of reasons, including housing and transportation options, school preferences, and work locations of a partner or spouse. This Regional Brief analyzes data on current commuting patterns, using 2022 New England data primarily. While the COVID-19 pandemic created a substantial disruption to commuting behavior, the spatial relationships between home and work addresses that we observe in 2022 are remarkably similar to those of 2019, suggesting that the patterns described for New England in this brief are fairly stable over the short term and that effects of hybrid and remote work arrangements on the region’s workplace–residence landscape are subtle. Recent research also indicates existing “flexible work” arrangements are overwhelmingly hybrid, requiring considerable “on-site” presence, and that fully remote work arrangements have grown increasingly rare since the height of the pandemic, accounting for less than 12 percent of workers employed by firms as of 2022 (Barrero, Bloom, and Davis 2023). |

| Abstract: | This study analyzes the supply chains, technological independence and domestic value added (DVA) of the Chinese EV industry by tearing down two popular models: the BYD Seal and the Tesla Model 3. It is the first study to use teardown data for two representative EV models to estimate the distribution of the value added in China EVs and the tasks performed by the makers’ suppliers. We find that 92% of BYD’s suppliers are in China and 65% of them are Chinese domestic firms, which produced 82% of the parts and components embedded in the BYD Seal. The localization of Tesla Shanghai’s supply chains is even higher, with more than 96% of Tesla Shanghai's suppliers in China, and 62 local Chinese firms participating in the supply chains to produce almost half of the parts and components in Model 3. 90% of the BYD Seal’s retail price is DVA generated in China, while only 45% of the total value of the Model 3 manufactured at the Shanghai factory is attributed to China. The extensive participation of Chinese firms in supply chains BYD and Tesla implies that the Chinese EV industry has achieved technological independence in the sector. However, foreign firms remain dominant in the supply of semiconductor chips: 97% of the chips used in the Model 3 are either imported or manufactured by wholly foreign owned ventures, while more than 50% of the semiconductor chips used in the BYD Seal are procured from foreign suppliers. |
