In planning expressways, what is emphasized about the placement of developments?

In the context of planning expressways, placing developments well back from the highway is emphasized primarily to minimize the potential negative impacts associated with high-speed traffic. This includes reducing noise pollution, providing safety from accidents, and ensuring smoother traffic flow on the highway itself. When developments are set back, they can mitigate the distractions for drivers and create a buffer zone that protects residential and commercial areas from the direct effects of highway traffic.

Moreover, by maintaining a significant distance from the expressway, the development can ensure that it does not interfere with the expressway's primary function as a high-capacity roadway. This allows for a more organized urban environment where expressways can efficiently serve their purpose without being congested by local traffic entering or exiting too frequently. Additionally, this approach promotes better land use planning and integrates green spaces, enhancing the overall aesthetics and environmental quality of the region.

In contrast, locating developments too close to the highway can lead to increased noise, air pollution, and diminished property values, which goes against the goal of creating sustainable and livable communities.
