This reconstructions shows the transformation of a roundabout into an orthogonal configuration with signalized traffic control and a more balanced allocation of space between different modes.
Reduce lane widths and add dedicated transit lanes, protected cycle facilities, and an improved walking environment.
Reduce corner radii to limit the speed of turning vehicles. Reclaim these corners for additional pedestrian space and to shorten crossing distances.
Align the number of travel lanes through the intersection. Mark skip lines to direct users on continuous paths.
Introduce dedicated, bidirectional transit facilities to reduce traffic congestion and increases total street capacity.
Ban turns that cross the transit lanes on unsignalized intersections.
Take steps to activate wide central medians, which are valuable but underused public space. Use the wide median along the transit corridor for transit shelters and stations. Design refuge spaces to align with pedestrian crossings, to provide access to stations, and to offer seating opportunities recessed into landscape.
A bidirectional cycle track is installed in the center median to create activity and utilize the space for mobility and recreational use. The cycle track is continuous, with a protected center crossing and access to side-running cycle tracks on either street.
Protect cyclists by adding corner refuge islands and forward stop bars that make them more visible to oncoming and turning vehicles.
Wide medians should be landscaped and planted to increase permeability, water infiltration, shade, and biodiversity.
