Case studies of positive and negative interrelationships between housing and public transportation

Paris
City's infrastructure is designed to weave between public transportation and housing such that one uniform system is created; Metro lines run under the main streets and boulevards, multiple stops are frequesnt and layed-out on a grid throught the city. Above ground, main circulation hubs where major lines intersect (La Bastille, Chatelet/Les Halles, Gard du Nord, Gard de Lyon, etc) are designed to stand out among its surroundings, but do not diminish from the neighborhoods' effectivit; The residences in closest proximity to these stations are not considered to be less desirable due to noise issuses and other related problems, but are instead popular and on high demand. Such a phenomenon is only possible due to successful city planning, and a clear vision of the city's needs.
