Since the fact that the non-signal roundabout allows less flow rate, and with the increasing of roundabout flow rates, a series of problems have occurred in respect to traffic jams, rising accident rates, growth of traffic delays, increasing of saturation degrees, etc. Arrangement of signal control help to enhance the capacity at roundabout and security, but there exist a big difference for applicable conditions and traffic efficiencies under different signal control methods. The main concern of this text, on the foundation of Left-turn with Two-stop Control Method at Roundabout with consideration of the number of different entrance paths and on the basis of signal control theory and optimal method, is on the four control methods related with "Control of In-turn Discharge Clockwise at Signal-entrance Path", "Control of In-turn Discharge Clockwise at Signal-entrance Path + Interlace of Minor Flow", "Association Roundabout Control at Multi--entrance Path" and "Associated Roundabout Control at Multi—entrance Path + Left-turn Inductive Control". It is on such a basis that the methods analyzing the effect rule on capacity come from the signal period of time and space strategy parameters and radius of island under different signal control methods by applying approaches of numerical calculation and experimental traffic engineering. The research achievement will perfect the theory system for signal control roundabout and provide technical support for the reconstruction of uncontrolled roundabouts as well as selection of signal control methods for roundabouts, meaning significant application value.
