The Village of Glenview

Patriot/Costco Roundabout

2022 public improvement project

Project description​

The Village of Glenview is implementing a roundabout at the intersection of Patriot Boulevard and the Costco Access Roadway to improve traffic operations and to make the conditions safer for pedestrians, cyclists and motorists.

Since the development opened, customers of the area businesses experience regular traffic delays exiting and entering the Costco, Costco Gas Station and Home Depot sites due to competing turning movements and high traffic volumes, particularly during peak hours of operations. The proposed intersection modifications will improve traffic operations and allow more vehicles to proceed on their way without needing to wait, improve safety and reduce vehicle emissions at this intersection, as well as make the conditions safer for pedestrians and cyclists.

Installing roundabouts in place of traffic signals or stop signs has been found to reduce carbon monoxide emissions by 15-45 percent, nitrous oxide emissions by 21-44 percent, carbon dioxide emissions by 23-34 percent and hydrocarbon emissions by 0-40 percent. Constructing roundabouts in place of traffic signals or stop signs also reduced fuel consumption by an estimated 23-34 percent​.

In addition, the Village's traffic study showed that during peak hours of traffic, the Level of Service (LOS) at the intersection will improve from a 'C' grade to an 'A'. An 'A' grade intersection is defined as one that is highly stable with free-flow conditions and little to no congestion.​

A dedicated southbound right turn lane will also be added at this location to address existing traffic queuing during peak hours of business operations. Decorative colored concrete islands, street lighting and landscaping are also planned to enhance this business corridor within The Glen.

Construction staging will be implemented to minimize disruptions to businesses during construction, with an anticipated start in June 2022.
