Function Area Defining of Freeway Ramp

Abstract

Based on existing research and standards ,this paper proposed a new method of freeway ramp function area calculation, divided the ramp into upstream function area, downstream function area and ramp function area, and redefined each function area. Moreover, according to the relationship among vehicle speed of certain point, the time required to change lanes , design speed and other parameters,modified the time of a lane change in the "Traffic Engineering Handbook", proposed new equation of each area and figure out the length.
