Impacts of reducing lance widths on Urban arterials in Utah

Reducing vehicle lance widths is often considered a way to decrease vehicle speed and increase road safety. According to the comprehensive street design guide jointly published by the American Society of Civil Engineers (ASCE), the National Association of Home Builders (NAHB), the Urban Land Institute (ULI), and the Institute of Transportation Engineers (ITE), "designers should select the minimum lane width that could reasonably satisfy all realistic needs, thereby minimizing construction and maintenance costs, while at the same time maximizing livability of the community." This approach is also likely to provide more space for active transportation infrastructure.
