NACTO-GDCI focuses on the critical role of street design within urban environments around the world. As part of the Bloomberg Initiative for Global Road Safety NACTO-GDCI has produced a Global Street Design Guide (GSDG), which is a timely resource that will set a new global baseline for designing streets and public spaces while redefining 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 and mobility for all users, environmental quality, economic benefit, public health and overall quality of life.
