Abstract:

This paper proposes a single release based signal control method for four-leg roundabouts. Single release is a signal control method of roundabouts, which makes each approach as a single phase, and releases the vehicles of each approach clockwise. In order to improve the capacity, two kinds of optimizing control schemes are presented. Based on the schemes, the phase design was made and the Webster’s optimal cycle length formulation was improved. By comparing the two optimizing signal control schemes, the applicable condition of the signal control schemes is discussed. Finally, a simulation study was conducted for a real Roundabout, and the result shows the validity of optimization control schemes.

Supplemental Notes:

This paper was sponsored by TRB committee ANB75 Roundabouts.
