New Urbanism and Smart Code communities are great because they offer a holistic approach to urban planning that prioritizes walkability, sustainability, and community engagement. These communities are designed to promote a sense of place and encourage a vibrant social and cultural life by incorporating mixed-use development, public transportation, and open spaces. New Urbanism also promotes human-scale design that takes into account the needs of pedestrians and cyclists, resulting in a safer and more accessible environment for all. Smart Codes, on the other hand, provide a set of zoning regulations that encourage sustainable development, such as energy-efficient buildings, renewable energy, and low-impact transportation. These codes also aim to create a better sense of community by promoting local businesses and preserving historic buildings. Overall, New Urbanism and Smart Code communities offer a promising alternative to conventional suburban development, as they prioritize sustainability, livability, and community engagement.

Roads are typically narrower in Smart Code communities for several reasons. Firstly, narrower roads help to slow down traffic, creating a safer environment for pedestrians, cyclists, and drivers alike. This can lead to fewer accidents and injuries, and also encourages more sustainable modes of transportation like walking and biking. Secondly, narrower roads also promote a more compact and walkable community by reducing the amount of space dedicated to cars and parking. This allows for more space to be allocated for public spaces, sidewalks, and green areas, which can enhance the overall livability and sense of community in the area. Finally, narrower roads can also contribute to a more aesthetically pleasing environment by reducing the visual impact of cars and promoting a more human-scale environment. Overall, narrower roads in Smart Code communities are designed to promote safety, sustainability, and a stronger sense of community.
