Engineering focuses on the infrastructure in a neighborhood that contributes to a safer and more pleasant walking and biking experience. Children need well-designed, well-built, well-maintained and accessible facilities to successfully and safely walk or bicycle to school.

Engineering strategies might focus on such issues as slowing down traffic, creating safer crossings or even making sure school routes are well-lit. These measures can be low-cost easy fixes, like painting curbs and crosswalks or adding signs. However, some communities might need more high-cost measures, like ADA compliant sidewalks.
