<br /> Project Description:
<br />
<br /> This project is for installation of new traffic signals and modification of existing signals or installation of roundabouts at various intersections in town. Potential
<br /> candidate intersections include: Thurston Rd. & 66th St., S. 42nd St. & Daisy St., S 42nd St. & Jasper Road, 42nd & Marcola Road, 28th & Main, 21st & Main,
<br /> 40th & Daisy St. and 28th & Centennial. The modification of signals may include change to permissive (ef# turn at some existing signalized intersections.
<br /> School speed zones beacons will also be implemented under the Traffic Control Projects.
<br /> Justification:
<br /> As traffic increases, additional traffic intersections will not operate in an acceptable manner with stop sign control. The intersections will meet roundabout or
<br /> signal warrants. New signals or roundabouts will need to be installed. The modification of existing signals is needed to maintain adequate traffic safety and to
<br /> enhance traffic flow.
<br /> Relation to Plans:
<br /> This project is consistent with the Metro Area Transportation Plan for improving traffic flow, traffic safety, and reducing vehicular accidents.
<br /> Maintenance Impacts:
<br /> Traffic signals will increase costs for power, lamp replacement, and timing modifications. Roundabouts will increase costs for irrigation and landscape
<br /> maintenance. Annual cost for roundabouts is about half the cost of traffic signals, with annual per signal cost being about $6,500 and annual roundabout
<br /> maintenance cost being about $3,300.
