Concept of compound geometric design for at-grade intersection is presented, and in functional, economic and environmental concept's way at-grade intersection's geometric design is elaborated. Qualitative and quantitative research is provided for intersection's channelized and flared design, including detailed analyses for pocket lane, crossway and traffic island. When conventionally channelized design of signalized intersection isn't possible or these effects are poor, an unconventional geometric design for intersection is brought out and 5 kinds of modes are systematically studied. An example is illustrated to urban signalized intersection compound design's splendid future and deep importance.

To facilitate this review an S-Paramics model was used to test several options. These options included removing signals at some junctions while relating pedestrian crossings, adding signals at a currently un-signalised junction, implementing active signal control and, finally, building a roundabout to replace a major signalised junction.
