"According to the National Association of City Transportation Officials, narrower lanes promote safer driving conditions, aligning with findings that wider lanes can lead to increased crash rates."
"A 2023 study by Johns Hopkins indicates that lanes around 12 feet wide are linked to higher crash rates, while narrower lanes between 9 and 10 feet are safer."
The Urban Transportation Commission has unanimously approved a resolution to adopt 1- to 2-foot narrower traffic lanes on larger Austin streets, reducing standard lane widths to 10 feet and constrained lanes to 9 feet, while maintaining 11 feet for lanes heavily used by larger vehicles. This shift aims to improve road safety based on research, including a Johns Hopkins study, which shows that 12-foot lanes are linked to higher crash rates due to promoting faster speeds and inadequate safety infrastructure. The recommendations align with national transportation standards, promoting a safer urban environment.
