Suggested Improvements

SETTING SPEED LIMITS & REDUCING SPEEDS


Will lowering the speed limit reduce speeds?

No. Studies show there is little change in the speed pattern after the posting of a speed limit. The driver

is much more influenced by the roadway conditions.

What are the effects of the posted speed limit?

Compliance exists only when expectation is met.

Lower posted speed limits do not reduce speeds.

Higher posted speed limits do not increase speeds.

Read the road, not the sign.

REDUCED CONFLICT INTERSECTIONSCOMMONLY REFERRED TO AS “J-TURNS”

HOW DO THEY IMPROVE SAFETY?

WHAT OTHER BENEFITS DO THEY OFFER?

1. US 71 and County Rd 24, Willmar

2. Hwy 212 and Hwy 284, Cologne

3. Hwy 65 and 169th Avenue, Ham Lake

4. Hwy 53 and County Rd 52, Cotton

5. Hwy 36 and Demontreville Trail, Lake Elmo

6. Hwy 169 and Hwy 22, Saint Peter

7. Hwy 169 and St. Julien St, Saint Peter

Reduce right-angle crashes by decreasing conflict points Reduce fatalities and injuries caused by broadside crashes

on 4-lane divided highways Studies show a 70% reduction in fatalities and a 42%

reduction in injury crashes

Can be designed and built in approximately one year Often less expensive than constructing an intersection

with a stop light or roundabout and are a fraction the cost of building an interchange

Acquiring additional land is typically not needed
