Street Type and Walking Culture

Walking culture: how far are you willing to walk? How easy to access buildings on foot?

.

New York City is available to access agglomeration of approximately 6,000 buildings but if you are in Indianapolis it’s only about 900 buildings within 1000m walk range or about a 15-minute walk.

Step 3: Mode Choice /Split— What travel mode is used for each trip? (Type of mode choice, e.g. bus, train, subway, walk, bicycle, etc.…)

Step 4: Trip Assignment — What is the route of each trip? (Determine the routes for travelers to reach their destinations)
