As a sub to OHM, MTJ provided operational analysis (Rodel), development of 3 concept alternatives, and preliminary/final horizontal design for this intersection. MTJ conducted a traffic planning level review of the system of the existing context and intersections.

The City of Dublin needed design improvements to optimize safety for all modes, accommodate large trucks, and meet long-range operational requirements for the intersection while minimizing adverse impacts to the existing and proposed adjacent properties.

A safety study identified a roundabout as the preferred intersection type for the Canton Rd./Market St./Robindale Ave. intersection. MTJ was retained to evaluate and develop a preliminary and final roundabout design for this highly constrained and skewed intersection to ensure optimal safety for all modes.

MTJ Engineering’s Mark Johnson, P.E. provided the horizontal design, signing and marking recommendation for this roundabout project in Gahanna, Ohio, working as a technical expert to MS Consultants.

MTJ Roundabout Engineering was responsible for this project's analysis, horizontal design, and public outreach support. MTJ’s context-sensitive solution provides the city with excellent redevelopment opportunities through improved traffic flow and safety, as well as improved pedestrian facilitation and business access management.

The Village of Waunakee, WI, wanted to maintain a two-lane roadway through their historic downtown. Waunakee and WIDOT sought a solution to reduce congestion and improve safety and traffic flow at this existing signalized intersection. A feasibility study showed a flared two-lane entry roundabout would alleviate existing traffic delays and improve safety for all modes.

The Town of Estes Park retained MTJ to provide a peer review and develop an optimized concept through final horizontal geometrics for this challenging, constrained, and skewed intersection. Once constructed, the MTJ corrective design ensures optimal safety for all modes and community acceptance.

MTJ Roundabout Engineering delivered an innovative compact, high-capacity, multi-lane design that facilitates business access, a safe pedestrian environment, and adequate traffic flow for this mixed-use commercial area.
