Vehicles Using The On Ramp Accelerate From 0 To 70 Mph In Order To Merge With The Freeway Traffic They Should Safely Re 1 (53.41 KiB) Viewed 39 times

Vehicles using the on-ramp accelerate from 0 to 70 mph in order to merge with the freeway traffic, they should safely reach 70 mph before the Soof weaving zone (distance "X"). Vehicles using the off-ramp are expected to decelerate from 70 mph at the end of the soon weaving zone to mph at the end of the ramp (distance "Y”). What is the minimum safe length of the entire weaving segment (X+500ft+Y)? Use the following assumptions, and state any other assumptions used: The design vehicle has an acceleration profile equivalent to the equation at = 4.2 -0.037u There is zero grade on both on-ramp and off-ramp, and both ramps are sufficiently straight to ignore any curvature. Perception-reaction time can be disregarded . traffic flow .
