The streets of commercial districts play an important role in the social fabric of communities. A well-designed streetscape provides an opportunity for thriving commerce, aesthetic enjoyment and public forum. The purpose of this study was to investigate how different elements of streetscape design influence a person’s preferences for the space. Using 3D visualizations of existing and possible future conditions, we studied the effects that infrastructure design had on perceived safety and attractiveness. Our study site was a small college town in the US. Results demonstrate that green infrastructure, including trees and bioswales, improve attractiveness and safety. Parking strategies also have an effect on safety and attractiveness – the fewer opportunities for parking, the higher the perceived safety. Participants were clear that any change would be an aesthetic improvement, but there was no strong preference between any of the non-existing conditions. 3D visualization provided an opportunity to test for perceived differences by allowing the control of environmental variables and design elements.
