A study on expressway merging and diverging traffic operation / Nurul Qastalani Radzuan

Merging lane is a path for drivers to accelerate their vehicle at a desired speed from the ramp terminal prior into entering the highway main stream. Conversely, diverging lanes allow the drivers to slow down their vehicle enabling them to enter the ramp terminal conveniently. The length of the spee...
