Knoxville TN Road Diet

August 2017

Compare these two photos of Cumberland Avenue – a “before” photo, shot by a News Sentinel photographer several years ago, and an “after” photo taken this morning (August 2017).

With the reconstruction of Cumberland mostly completed, visitors will notice wider sidewalks, turn lanes at intersections, and a landscaped median. About 100 trees will be planted this fall, further greening up The Strip.

The massed utility poles are gone, too. Decorative LED streetlights have replaced the standard roadway lights on wooden poles.

Plus, new development and private investment – totaling more than $190 million – are changing the look and increasing the vibrancy of The Strip.

Join Gov. Bill Haslam, the City team and Cumberland merchants and stakeholders at 4 p.m. today, Baker Center, for the official ribbon-cutting for the new Cumberland!

Boulder Junction compared to Amsterdam

By Dom Nozzi

June 5, 2017


A comparison of Boulder Junction in Boulder CO (image on left) and a street we stumbled upon during our recent trip to Amsterdam (right).Amsterdam, May 8, 2017 compared to Bldr Junction

Note the walkable, comfortable, human-scaled, romantic character of the Amsterdam street compared to the new street in Boulder. Boulder Junction is a new town center in Boulder intended to be compact and walkable, but the center fails to provide a comfortable, enclosed, walkable human scale.

Open space that is too vast, setbacks that are too large, and streets that are too wide.

If we can generalize the Boulder design experience with that of much of America – and I think we can fairly do so — this comparison clearly shows that Americans have failed to learn how to build walkable places in recent decades. Or find the political will to do so, since much of the unwalkable design was requested by citizens who do not know the ingredients of quality urbanism and quality streets. Citizens tend to request large building setbacks, low densities, oversized roadways, and excessive open spaces.

In part, this is done to seek to retain or restore convenient, comfortable car travel. Failing to create quality urbanism, then, is a signal that Boulder is much more of a car culture than a walking (or transit or bike) culture.

Efforts to promote happy car travel, ironically, worsens car travel as such efforts result in increased per capita car travel, which crowds roads and parking lots. And worsens the quality of life (and safety) for people — particularly people not in cars.

A Line in the Sand for Road Size


By Dom Nozzi

July 30, 2003

I was having a conversation with someone who asked me if I agreed that a 4-lane road would ruin the rural character of a rural location. I agreed that a 4-laner would ruin rural character.

I would go beyond that: I don’t believe that a community should ever build a road bigger than 3 lanes.

At some point, a community must draw the line and say that enough is enough. That going beyond a certain road size is too destructive of our community.

Everyone has some idea of some limit. For some, it would be, say, 12 lanes as a limit. For others, it might be 6 lanes. For me, it is 3.street without on street parking

Indeed, when I was a long-range transportation planner for the City of Gainesville Florida, I succeeded in (briefly) having that City insert a policy in its long-range transportation plan that says the City shall never build a road again that is larger than 4 travel lanes (I would have preferred that we limit it to 2…).

Of course, as one would expect in a car-happy city such as Gainesville, that sort of policy only lasted a year or two before it was hastily expunged from the plan by our beloved defenders of cars…

It is not inevitable that a growing community must forever enlarge its roads. If more car volume capacity is felt to be essential, that added capacity can come from more community-sensitive means than conventional widening. Or, I see no reason why a community could not say “We have decided, as a community, that we will NOT go beyond a certain road size in order to protect our health, safety and welfare. If that means that our roads cannot accommodate any additional cars, so be it.”

Such cars can self-regulate themselves by choosing a different route, traveling at a non-rush hour time, or selecting another way to travel.

There is no law that says a community must accommodate an endless stream of forever increasing numbers of cars.

Should Boulder Prohibit Bicycling on Sidewalks?


By Dom Nozzi

August 16, 2014

Boulder Colorado is well known for providing an impressive range of bicycling facilities. However, the City prohibits bicycling on several sections of commercialized streets.

I have serious concerns about this prohibition. I should state first that I am very well aware of how poorly bicyclists mix with pedestrians on sidewalks – particularly sidewalks that are heavily used. An important reason for the incompatibility is that bicyclists and pedestrians have a very large speed differential, and pedestrians often move from side to side unpredictably. For these reasons, I typically tend to oppose bicyclists on sidewalks. I was a bicycle commuter in Florida for about 25 years, and I made it a point to almost never ride my bike on a sidewalk, and would strongly prefer it if I (and other bicyclists) NEVER had to be on a sidewalk. Professionally, I have spent much of my career strongly advocating that bicyclists not be allowed on sidewalks, and often argue with friends and others when I frequently hear the claim that bicyclists are safer (and belong) on sidewalks. I have always taken the position that bicyclists don’t belong on sidewalks.

It is therefore highly ironic that here in Boulder, where bicycle facilities are extremely high-quality and abundant, I suddenly find myself riding on sidewalks almost every day I ride. Not because I prefer it, but because I feel forced to do so.

There are two main reasons why, for the first time in my life, I am often riding on sidewalks. First, Boulder has a number of extremely important streets (streets that most all travelers understandably want to travel on frequently – that includes bicyclists) that are nearly impossible for a bicyclist to ride on – including for highly experienced, skilled bicyclists (I include myself in that category). These car-only, large_SMBIKE 1 MCNISHhigh-speed highways are exceptionally hostile to bicyclists. The main offenders are Broadway (particularly in the town center), Canyon, and 28th Street. Second, Boulder has a made what I believe is the very bad decision to convert a number of two-way streets to one-way operation in the town center. A growing number of cities are converting their one-ways back to two-way operation after discovering how toxic they have become to a healthy city and street. With one-way streets, bicyclists are presented with three extremely undesirable choices: (1) opt for a very inconvenient, out-of-the-way route that adds significant distance to the bicycle trip; (2) ride in the street against traffic (which is extremely dangerous); or (3) ride on the sidewalk. I typically opt for #3, even though I am well aware of the incompatibility-with-pedestrians problem.

Given all of the above, I believe it is extremely problematic for Boulder to not allow bicycling on commercial streets such as town center Canyon and Broadway (or on one-way streets).

By doing so, Boulder is taking the position that bicyclists are not allowed to bicycle on some of the most desirable, heavily used routes in the city. Only pedestrians and cars are allowed on those streets. While the regulation is a significant inconvenience for someone such as myself, it is much more inconvenient (and extremely discouraging) for the “interested but concerned” bicyclist that Boulder is now seeking to put special efforts into encouraging.

Again, I tend to be strongly opposed to allowing bicyclists to ride on sidewalks. But when the Colorado Department of Transportation (and the City of Boulder?) opted to design town center Broadway and Canyon to be hostile, car-only superhighways (and opted to convert certain two-way streets to one-way), an unavoidable consequence (in my opinion) was to force the City of Boulder to take what is normally a very undesirable position (in some ways, a Faustian Bargain): allow bicyclists to ride on sidewalks on those exceptionally hostile streets. Building car-only Broadway and Canyon in the town center (as well as creating one-ways) makes such a policy nearly unavoidable, unless the City of Boulder wishes to significantly handicap or inconvenience bicyclists by not allowing them to ride along Broadway or Canyon in the town center.

In sum, I believe that the regulation discriminates against bicyclists. I should add that I recommend allowing bicyclists on sidewalks with deep regret (for the reasons I mention above), which to me adds urgency to the need to, say, road diet Canyon and Broadway in the town center to make them Complete Streets, because in general, bicyclists do not belong on sidewalks. But until that day of reform for Canyon, Broadway, and the one-way streets comes, bicyclists should be allowed on the sidewalks of those streets.
