Blacow Road Improvement Plan, Nishita Kandikuppa

City and Regional Planning

Providing safe and accessible entrances to schools, especially elementary, middle, and high schools where children are below the age of 18, should be of utmost priority to cities. Providing wide sidewalks, painted bicycle lanes and continental crosswalks (with the lateral lines) are just basic infrastructure improvements that can be made within the vicinity of a school. However, due to lack of funding or attention from the city departments, many school entryways are being neglected and the direct impact of this is increased collisions among students, drivers, and bicyclists. My senior project studied one such school in Fremont, California where the …

Walnut Overcrossing: Bridging A Gap In San Luis Obispo's Active Transportation Network, Chris Murphy

City and Regional Planning

Highways in the United states were designed to connect us; however, they ultimately created a loss of connectivity within communities. Physical and socioeconomic segregation are a staple among American cities due to the greed of the automobile industry beginning in the 1920’s (Klein, 1996) and racially fueled highway engineering of the 1950’s (Mohl 2002). Public space doesn’t require a key, and in a truly democratic society, these areas are inclusive to all (Deutsche 1992), however, there are still holes in connectivity, spurring automobile dependency, siloed neighborhoods, environmental justice issues and ultimately, only benefiting those with access to an automobile and …
