MANDAN, N.D. (AP) — Temporary mini-roundabouts and pedestrian curb extensions in Mandan are drawing mixed reviews from drivers and pedestrians.

City engineers are collecting data this summer to determine if the changes make intersections safer and more efficient. An online survey is open until mid-August for residents to voice their opinions of the roundabouts, The Bismarck Tribune reported .

"The point is that it slows traffic but keeps it moving, and that makes it safer for pedestrians," said city planner John Van Dyke. "It just makes the intersection overall safer for all users."

The feedback received so far is more about the longevity of the roundabouts and possible funding sources related to their permanence, Van Dyke said. Some negative feedback involved the size of the roundabouts.

"We're just educating the public with regard to their use," he said. "I think a lot of the public believe they're too small, and they're intended to be mini-roundabouts, so they're small in nature."

The temporary roundabouts were funded by a grant from the North Dakota Department of Transportation. Vehicles can navigate the fixtures using bright red and blue paint, line markers and traffic posts.

Pedestrian Clinton Sauter walks from his apartment complex near downtown Mandan to work at the AID Inc. thrift store six days a week. He said he's seen the close calls pedestrians have with vehicles downtown.

"Especially for pedestrians, I think (the roundabouts are) going to be very helpful," he said.

The Mandan City Commission must sign off on the roundabouts, Van Dyke said. City engineers will present collected data to the commission in the fall.
