Roundabout & Intersection Design

Intersection design is critical to safety and flow of traffic. Intersection designs can take many forms, such as a four-way stop, signalized intersection, roundabout intersection, or alternative intersection designs like diverging diamonds. In our region, roundabouts are beginning to gain favor as an alternate to signalized intersections. MCE is experienced in intersection design of types, including roundabout, signalized and alternative intersections, and we also perform studies to help you determine which type of design will best meet your traffic needs. Below are a few samples of our work experience.

The North Little Rock Roundabout is located at the intersection of Pike Avenue (Highway 365), West Riverfront Drive (Highway 100) and West Roadway Avenue. Completed in 2010, this is the first major roundabout constructed in central Arkansas.

The roundabout on John DeShields Boulevard designed by MCE  is located at the intersection with NE Moberly Lane in Bentonville. The roundabout and associated street landscaping serves as a gateway to the internationally renowned Crystal Bridges Museum of American Art.

MCE is working with the City of Rogers to install a roundabout on Laurel Avenue at the intersection of Dixieland Road. Above a rendering of the intersection is shown. Public art designed by artist Ralph Irwin will be installed at the center of the roundabout.

A roundabout designed by MCE is being constructed in Little Rock on 9th Street near the Dassault Falcon Jet facility. The roundabout does not have a western leg because the facility will soon be expanding on property in the vicinity.

MCE is in the design phase of a roundabout for Saline County at the intersection of North Springlake and Lorance.

MCE has designed a mini roundabout for the City of Russellville at an intersection which is prone to accidents due to line of sight issues. Unique features such as flexible bollards are part of the design to accommodate larger truck traffic when occasionally necessary.

MCE has performed an intersection study for the City Branson for Wildwood Drive and Gretna Road intersection, a four way stop with three lane roads approaching from each direction. Congestion occurs at this intersection daily and becomes even more significant during busy tourism weekends. The study evaluated whether a signalized intersection or a roundabout will best improve the flow of traffic and safety of the intersection.

To model roundabouts and traffic simulation, MCE utilizes VISSIM software, the leading microscopic simulation program for multi-modal traffic flow modeling. The program produces a unique, high level of detail and accurately simulates urban and highway traffic, including cyclists and motorized vehicles. These screenshots are taken from a simulation for a proposed roundabout on planned aerial roadway in Russellville, Ark.
