Factor Standard Diamond Roundabouts Diverging Diamond Description
TRAFFIC OPERATIONS
20 Year Traffic Operation No Appreciable Difference Between the Three Options. Indication of acceptable traffic operations in design year peak hour conditions.
Reserve Capacity After Expansion Indication of acceptable traffic operations in future peak hour conditions. Roundabouts will need to be three lanes to accommodate projected traffic, which is not desirable to the City.
Relative Vehicular Safety Each interchange type will be designed to current AASHTO and safety standards, however, the crash rates and severity differ due to geometry and traffic operations.
Bicycle Operation / Friendliness Stress level of cyclists increase with merging into traffic or merging into the shared use side paths at the roundabouts.
Pedestrian Operation / Friendliness Signalized intersections will have pedestrian signals, and the roundabouts will have pedestrian refuge islands with crosswalks that only cross traffic going one direction.
COSTS
Initial Construction Cost No Appreciable Difference Between the Three Options. Construction cost only.
Expansion Construction Cost Construction cost only. (Note that the expansion costs are anticipated to be from City or private funds.)
Maintenance Cost No Appreciable Difference Between the Three Options. The standard diamond has signals and the most pavement, bridge, and storm drainage infrastructure to maintain. The diverging diamond has signals to maintain.
ENVIRONMENTAL STEWARDSHIP No Appreciable Difference Between the Three Options. Footprint of interchange in environmentally sensitive areas, amount of material needed to construct, storm drainage runoff, and other environmental factors where considered.
RIGHT‐OF‐WAY ACQUISITION Comparison of total acreage of right‐of‐way to be acquired.
AESTHETICS Roundabouts provided more space for aesthetics, however, MoDOT requirements limit features that can be included at the ramps.
ECONOMIC DEVELOPMENT No Appreciable Difference Between the Three Options. All three interchange types provide good access management and developable land for the impacted property owners.
