WalkSanDiego defines walkability as a place where people of all ages and abilities have safe, enjoyable, and easy access to their community on foot. There are 5 critical ingredients:
First, we need sidewalks on all streets. The way these are designed is very important. For example,
How many times have we crossed the street wtihout a crosswalk simply because the closest one seems too far away?
Street crossings should be available every 300 feet (about 1/2 the length of a block) to increase the safety and ease of crossing. Crossings should include:
Just like it sounds, engineers have tools they can use to slow traffic speeds and make it safer for walking, even while allowing cars to flow smoothly. Some of these tools include:
Curb extension - at intersections, extends the curb into the street to slow vehicles turning the corner and shorten the crossing distance for pedestrians.
Road diet - reduces the number of lanes and lane widths. By painting one lane instead of two, cars cannot pass one another. The narrow lane width gives drivers the impression they should slow down.

Roundabout - slows traffic at intersections without making cars actually stop. Yes, even fire trucks and emergency vehicles can go around!
This is the easiest point to explain. We all want to walk in places that are interesting and make us feel comfortable. Lots of small details can make the street more inviting.
Our communities are much more walkable if there are great places nearby that make it worth walking. This allows us to walk as part of our daily activities rather than getting into our car.
