Designing a Street for Greatness

By Dom Nozzi

When I think about designing or testing a street for greatness, I generally ask three questions:

1. Is the street charmingly human-scaled?

A great street, for me, features a very modest street width from curb to curb. The “curb radius” of the intersection is also essential. One of the most NE 3rd & 3rd2common crashes experienced by someone walking across an intersection is a person who is struck by a right-turning vehicle at the intersection. A wide (large) curb radius typically induces high-speed turning movements by motorists. Creating a turning (curb) radius which results in a tight turn movement by the vehicle will reduce turning speeds, and shortens the crossing distance for the person walking.

A street with charm and human scale also features an uninterrupted fabric of permeable, 24-hour buildings, which creates a sense of enclosure by butting up to the sidewalk. On-street parking layers both sides of the street. Added (and often quite important) bonuses are a framing canopy of street trees, and a street that is brick or cobblestone. Very little is more effective in creating romantic charm than brick or cobblestone.

2. Does the street design obligate well-behaved motorist travel?

In my opinion, there is very little that is more important for city street design than obligating slower-speed, attentive, patient, courteous driving by motorists. For these reasons, I tend to enthusiastically endorse traffic engineer Hans Monderman’s naked streets concept. The lack of well-behaved of driving, when streets are not designed to obligate such driving, is exceptionally toxic to cities.

Because of this, my favorite streets tend to be give-way streets. Two-way streets (with on-street parking) are so narrow that motorists are compelled to drive slowly, attentively, and courteously.

3. Is the street a complete street?

Obviously, a great street should be designed to create transportation choices. A “complete street” is one that is designed to be used comfortably, conveniently and safely by all forms of travel.

4. Is the street regularly active?

A great street should contain large volumes of pedestrians and bicyclists throughout the day and night. Such regular activity makes the street enjoyable, sociable, and safe.

Sure, there are great streets that don’t score well on these three questions. But I am convinced that they are great despite this.
