A new study reveals how the expansion of bike lanes and pedestrian spaces in urban areas has led to significant reductions in traffic fatalities and injuries. Researchers analyzed data from cities that implemented protected bike lanes and widened sidewalks, finding that these changes contributed to safer streets by slowing vehicle speeds and encouraging alternative transportation methods. The findings suggest that reallocating road space to vulnerable users can have immediate public safety benefits. The study also highlights the role of community engagement in ensuring these infrastructure changes are both effective and well-received.
