Approach to Streetcar Design
Establishing an Approach
What are the minimum design requirements to ensure that it will function well? (keep it simple)Are there ways to streamline or combine the functions of project elements?How can the design of the track system best fit into the existing built environment? (To retrofit rather than reconstruct)How can the impacts to the community be minimized during construction?

Conclusion
Streetcars can serve important role in a transportation network
– Promotes ridership– Serves more localized
market– Reduces auto trips
…first understand purpose and need of rail-transit investment
It is important for us as planners/designers to manage costs to keep viable funding sources
