Roundabout designs should be balanced to accommodate the mix of pedestrians, cyclists, and motorized vehicles (such as cars, buses, trucks, oversize loads, etc.) expected to use the intersection. Each user class has different characteristics and time/space requirements, and optimizing the design for one user class often reduces the suitability for other users. The task of the designer is to find the design trade-offs that optimize safety and operations for the entire mix of users of the intersection under consideration. This paper highlights a variety of issues related to "small" users at roundabouts, principally pedestrians and cyclists, and "large" users at roundabouts, namely trucks.
