Geometry > Bypass Entry > Bypass Entry Angle Фb ## Bypass Entry Angle ФbFree and Merge Bypasses have zero Entry Angle Exclusive Right Turns have the same entry angle as the Entry Geometry Yield Bypasses have an entry angle phi as shown below. The blue lines are the median lines of the bypass entry and the bypass exit. The red line a-b is tangent to the entry median at the point it intersects the yield line. The line c-d is tangent to the exit median at the point it intersected by line a-b. The point x is the intersection of a-b and c-d. The bypass entry angle phi is c-x-a. © Rodel Software Ltd |
