Research: More Complex Streets Are Safer

New research reveals that streets that are more complex can be safer because they force drivers to slow down.

Chris McCahill explains the study results in a piece for the State Smart Transportation Initiative, noting that “When roads feel safer, drivers often compensate by speeding up and paying less attention.”

A Swiss study found that drivers slowed down when design elements such as street parking and trees were present. In a twist, the study showed that drivers actually felt safer driving faster on streets with bike lanes — potentially because they are less concerned about cyclists in their lane. Another study showed that “Drivers tended to go slower in areas with more buildings and grass medians, while speeds increased in open spaces with clear views of the sky.”

Research like this affirms the impact that the design of roadways, buildings, and street-adjacent features can have on driver behavior. “More complexity—whether through buildings, trees, or parked cars—can help keep speeds in check and streets safer for everyone.”
