\begin{equation} \label{eqn:flow_ratio} Flow ratio=\frac{Q_{app}-Q_{conf}}{Q_{app}+Q_{conf}} \end{equation}  where $Q_{app}$ is the total flow rate at the approach and $Q_{conf}$ is the total conflicting flow (in the roundabout lanes at the beginning of the merging zone). It follows that a negative flow ratio would indicate that the conflicting flow is greater than the approach flow, and vice versa for a positive flow ratio. Mixed land use involved mostly residential and commercial land use, and institutional occasionally.
