Conventional intersection improvement strategies add lanes to accommodate increased traffic volume. In built up areas, augmenting lanes can become cost-prohibitive. Unconventional intersection configurations are effective in these situations. These intersections are generally symmetric in all legs. Depending on the traffic composition and available space symmetric treatments may not be highly efficient or effective. A simplified spreadsheet based methodology is proposed in this paper that can explore the strengths of relevant unconventional intersection configurations. The proposed method has the ability to develop hybrid intersection configurations that are asymmetric but appropriate for the situation. The strengths of displaced left-turn, jughandle and quadrant intersection design configurations are explored in this study to demonstrate the proposed methodology.
