This document contains a summary of two articles and citations for four sources related to urban planning and transportation issues. The main article summarized is by Donald Shoup discussing how minimum parking requirements imposed by cities actually hurt the poor. Shoup argues that by requiring free parking, cities subsidize car ownership which increases various social costs while raising costs for those who cannot afford a car. The cost of building the required parking spaces can exceed the net worth of many low-income households. The document also briefly summarizes an article about collaboration between LA Metro and the California High Speed Rail project to coordinate transportation and community development investments.
