Linear cities are urban designs that follow a single axis, such as a highway or railway. This form of development can be challenging because it often results in limited space for growth, homogeneity in land use, transportation challenges, sprawl, and social isolation. Limited space for development can cause high land costs, which can make the city less attractive to residents. Additionally, linear cities tend to be homogeneous, with residential areas on one side and commercial or industrial areas on the other, making it challenging to create diverse and inclusive urban environments.
Transportation can also be a significant issue in linear cities as they rely heavily on a single transportation axis, leading to congestion and limited mobility. This type of urban development can also be prone to sprawl, with low-density development stretching out along the transportation axis. This can lead to environmental issues such as air pollution, habitat destruction, and increased greenhouse gas emissions. Social isolation is another challenge in linear cities, as there can be long distances between neighborhoods, limiting interactions between residents and decreasing community cohesion. While linear cities have been successful in some instances, they require careful planning and management to address these challenges effectively.
