In the summer of 2015, the city of Boulder administered a different radical design to a different street; this time it was Folsom Avenue and the modification was to convert a four-lane auto street to two auto lanes, installing two separate protected bike lanes. In addition to the design of space within the right-of-ways, cities need to make decisions about what stimulates travel—that is, the purpose, amount, intensity, and design of land use. These discussions and land use planning and land use design stimulate equal, if not more, visceral reactions. The public reactions to these designs depend on many factors and their fashions tend to cycle over decades. Urban planner Victor Gruen aggressively employed changes in both land use and street design to stimulate activities in US downtowns throughout the 1980s. Most people agree that design has a spatial or geographical component; it is commonly associated in transportation–land use contexts with the scale of buildings or the layout of roads.
