Demonstration Event #1 |
|
Demonstration events are powerful ways of engaging the public in new ideas. It is much easier for someone to visualize a project once they have actually tried it out. Mist is working on performing a series of demonstration events. The first one is documented in the pictures below. |

In
May 2001, Mist built a temporary roundabout at the intersection of Spruce
and Higgins in Missoula- during a road closure at a bike race.

The
roundabout in action. One thing we did wrong was that we made the roundabout
too small- but this is another aspect of demonstration projects: to learn
for the next time (the roundabout should be large enough so that the path
of cars is deflected- to slow them down).

Notice
the high degree of visibility between the bike and car. If designed well,
with low speeds in mind, a roundabout is safer for pedestrians, cyclists,
and motorists when compared to a conventional intersection.

Three
types of circular intersections
|
|
Traffic
circle: primarily used for traffic calming
in neighborhoods- to slow down traffic and prevent accidents.
|
| Rotaries: large, fast, circular intersections. Traffic entering the circle has right of way (opposite for roundabouts). Rotaries are not recommended because of high-speeds, difficulty in maneuvering, and large space requirements. |
| *Roundabouts*: much smaller than rotaries, contain amenities for bicycles and pedestrians, vehicles in the circle have right of way (over vehicles entering), entering speeds around 15mph- huge potential for replacing or complementing signals. |
