Half of the traffic was placed on the north/south street and half <br />on the east/west street. The intersection used in these examples has a capacity of about <br />3,540 vehicles per hour, so these LOS B conditions represent traffic flow at about 54 pement of <br />the intersection's capacity. <br /> <br />The following exhibit is a screen capture from the City's traffic simulation model. It shows the <br />intersection as a two-phase traffic signal with the light just changing to yellow on the east/west <br />street. Note that more vehicles are stopped or are approaching queued vehicles (thus, slowing), <br />but the intersection appears uncongested. <br /> <br /> <br />
