Each year, 1.2 million people die from traffic fatalities, highlighting the need to design streets that offer safe and enticing travel choices for all people. Cities around the world are facing the same challenges as cities in the US, and many of these problems are rooted in outdated codes and standards. The Global Street Design Guide is a timely resource that sets a global baseline for designing streets and public spaces and redefines the role of streets in a rapidly urbanizing world. The guide will broaden how to measure the success of urban streets to include: access, safety, mobility for all users, environmental quality, economic benefit, public health, and overall quality of life. The first-ever worldwide standards for designing city streets and prioritising safety, pedestrians, public transport, and sustainable mobility are presented in the guide. Participating experts from global cities have helped to develop the principles that organise the guide. The Global Street Design Guide builds off the successful tools and tactics defined in NACTO's Urban Street Design Guide and Urban Bikeway Design Guide while addressing a variety of street typologies and design elements found in various contexts around the world. This innovative guide will inspire leaders, inform practitioners, and empower communities in realising the potential in their public space networks. It will help cities unlock the potential of streets as safe, accessible, and economically sustainable places.
