Hello everyone,
I am analyzing a curved ramp with three spans (36m, 45m, and 30m). The first two spans have a carriage width of more than 11.0 meters. However, between the second and third spans, there is a portion where the carriage width is less than 10.5 meters. In this regard, how many lanes should there be? Should I use three lanes (since 11/3.65 > 3.0) in the portions where the carriage width is greater than 11.0 meters and then reduce to two lanes where the ratio of carriage width to 3.65 is less than 3.0?
