Increase flow & calm traffic at the same time…yes, you can
Over 100 people came to the Hagerty center last night to hear the initial recommendations by traffic engineer Ian Lockwood. He was hired by the city of Traverse City to work with the community to redesign Division St. in a way that serves both the 20 to 26 thousand vehicles per day (VPD) and also the needs to address the hostility of the current design.
As mentioned in the previous post, roundabouts featured prominently in the recommended design. Certainly, that will be one of the major hurdles in the proposal as almost every community that proposes this traffic calming device goes through a feisty process from people resistance to change. Traverse City has already had one of those debates.
Still, other communities, like Clearwater Beach, FL have embraced the tool to such a high degree that they have actually petitioned to force the implementation of roundabouts. The result, the country’s busiest roundabout (video) that handles over 58,000 VPD while handling over 8000 pedestrians. All with a reduction in crashes and with a clear sense of place.
Clearwater, Florida’s signature roundabout
Still, roundabouts on Division St.?
Yes. Roundabouts have a proven record in accomplishing many of the concerns northern Michigan has with Division St. The key will be the follow through.
Done well, roundabouts fix a number of issues.
- For vehicles: increase traffic flow, improve time travel and access along the corridor, while reducing crashes (crash rates at the intersections on this route are some of the highest in the region).
- For the neighborhoods: despite the possible increase in traffic volumes, there would be lower speeds, improved noise control, less cut-through traffic*, improved east-west access and thus, increase home values.
- For non-motorized traffic: Lockwood admits that the proposal is not a ‘complete street’ and isn’t perfect, but that he is encouraged that the slower speeds will improve east-west accessibility for all modes of traffic. The plan also includes sidewalks and pathways along the corridor, including long-term development of a tree canopy. If a couple of crosswalks are included at places other than just the intersections, then active transportation will be increased and encouraged by improved safety, access, and a better sense of place along the corridor.
Of course, this is if the design is completed as intended and not turned over to a reluctant authority without the proper experience and motivation to embrace the project with enthusiasm. Have no doubt, although not completely out of the realm of possibilities, this design will be a political challenge.
Don’t be scared, be vigilant
This is where our elected officials, area power brokers, luminaries and neighborhoods will need to step it up and stand for something different. Last July Tom Vanderbilt, author of Traffic, explained in an article on Slate the difficult relationship Americans have had with roundabouts. Roundabouts are rarely popular when proposed and take leaders willing to make un-popular decisions to make them happen.
In the article, titled Don’t Be So Square, he describes exactly the scene from last night’s presentation:
After a period of study, the engineers propose a roundabout. The engineers, armed with drawings and PowerPoint slides, visit a community meeting. They try to explain the benefits of their proposed design in clear language, though they may occasionally drop phrases like entry path overlap or inscribed circle diameter. Townspeople raise concerns. Roundabouts are not safe, they say. They are confusing. They are bad for pedestrians. They will hurt local businesses. They are more expensive than traditional solutions. The local newspaper reports this, adding some man-in-the-street comments from “area drivers,” who profess not to like roundabouts, even making dark references to “circles of death.”
But here is the key…
More and more the story is not ending like Traverse City’s previous experience, but rather as Vanderbilt writes, “then, the roundabout is built, the safety record improves, traffic congestion doesn’t seem any worse than before, and the complaints begin to fade faster than white thermoplastic lane markings in the heat of summer.“
Roundabouts work, in part, because they increase the ‘awareness’ and ‘vigilance’ of drivers. People are no longer blindly following orders; they are now forced to pay attention and negotiate with real humans.
The key to implementing roundabouts will also take vigilance.
More examples and discussions of Lockwoods presentation can be expected, including more discussion on roundabouts in general and along Division.
I love having new material!
* The one exception to the cut-through traffic is the 11th St. corridor east of Division St., however, only if the city fails to implement some creativity along that street. 11th Street wouldn’t need to be closed off to traffic, but using other traffic calming and controlling devices, incentives for cut-through traffic could be reduced & calmed.

Excellent comments, Gary. I came away last evening very enthused about the possibilities of a series of roundabouts. I will definitely be supporting them as part of the solution for Division St.
I’ve bike toured (loaded bicycle with tent, sleeping bags, cooking equipment) many months in NZ & Oz (Australia) where they have lots a roundabouts. I never found them to be a problem on the roads I traveled.
Another comment from Slate article by Vanderbilt:
Did a bit of browsing and found two things of interest from MDOT (yes Michigan DOT!). Have a look at http://www.youtube.com/watch?v=4YbE9pZACYM 8:47 min video by Michigan DOT. Even though it was originally produced by Washington State, and has numerous palm trees, it was adopted and presented by our DOT.
And for a list by MDOT of roundabouts in Michigan see:
http://www.michigan.gov/mdot/0,1607,7-151-9615_44557_44558-140988–,00.html
And at http://www.michigan.gov/mdot/0,1607,7-151-9615-139335–,00.html is the following comment:
“Modern roundabouts provide greater safety and traffic flow. Learn why and where MDOT is building them.
A roundabout is a type of circular intersection that has been used in Europe for several decades. In recent years, MDOT has constructed several roundabouts on state trunklines and more are planned.
• They keep traffic moving; this decreases emissions and improves fuel economy.
• Increase safety because there is no stopping in a roundabout, no left turns across opposing traffic lanes, and all vehicles must maintain similar speeds.
• Lane design and pavement markings guide drivers through the intersection.
• They force vehicles to slow to a safe speed for the intersection.
• Can be landscaped to offer an attractive gateway into a city or other area.”
Looks like MDOT will be a willing player as long as our desires & plans are not too costly, and can be planned within the time limits they may have to demand (sources of dollars for the Division St work).
Only thing I wish is that Ian Lockwood’s presentation had been filmed. He was very persuasive and complete in his comments.
Living in Washington, Roundabouts are a norm there..First time on them a bit intimidating, but the flow was always there..I also think it is important for people to know that its not the same as the roundabouts that are on Webster St.
Gary -
Keep the info flowing. I am really interested in this concept, but there is a lot of due diligence we all have to do to make sure it will work. Then comes the difficult job of making sure the city is on board. The two concerns I heard the most were, cut-through traffic, esp on 11th, and how pedestrians crossing Division would fare.
Great comments from everyone, although I’m not so sure about the communist concern…?
What Will points is actually exactly what you want with roundabouts. They are designed to engage the minds of motorists so that they interact with the environment–forcing people to think. It raises awareness and hence the increase in safety across the board. Locals will be the vast majority using the corridor and they will serve as valuable ‘trainers’ to the tourists.
I agree with you Ross. It will take some work, but from experience with them I think if we can make this big leap with intentional design, that it will have many long-term benefits. I’m anxious to see the ‘finalized’ concept.
There are many ‘training’ videos out there to address the fears and uncertainty about pedestrians, but nothing is going to alleviate them better than using them & encouraging confidence in people to use the public space as if it is they own it-walking & biking with confidence.
The great advantage of roundabouts is it increases the need for social negotiation. No longer are people responding to signals and signs, but rather they must make eye contact with each other as motorists, cyclists and walkers. As Division St. is now, most motorists drive it with blinders on.
The 11th St. increase of cut-through is a key element, but not as difficult as most people assume. Just a quick brainstorm and I see a great opportunity to experiment with pinch points, islands, bump outs…the engineering and design is easy. The political will, we shall see…
I first experienced roundabouts in Jamaica. There are less cars there, but the drivers seem a little crazier. Regardless, the roundabouts worked. The roundabouts currently on Webster are not effective; there isn’t adequate space for a car between each “spoke” of the road. I’m all for roundabouts in town if they do them right.
