Create a comprehensive proposal for a new, sustainable public transportation system that takes into consideration the needs and preferences of commuters, the demographics and geography of a major city, the city's environmental goals, and the available funding. Your proposal should include an analysis of potential routes, modes of transportation (e.g. buses, trains, light rail), the frequency and scheduling of service, estimated costs, revenue streams, and a plan to engage the public and garner support for the project. Your proposal should be written in a clear, concise, and persuasive style, supported by data and research from credible sources.
