The methods of analyzing roundabouts described in the chapter are primarily based on the HCM 7th Edition. As such, this chapter highlights motorized vehicle analysis while multimodal considerations are limited to level of traffic stress and LOS. Furthermore, this chapter only briefly reviews safety analysis of roundabouts. For more information on safety analysis of roundabouts, see

Chapter 5 and Chapter 6

. This chapter provides roundabout-specific guidance on Microsimulation (Microscopic) analysis, which can be used to verify results of the empirical method found in the HCM 7th Edition. For general guidance on microsimulation (microscopic) analysis, see
