1. A system for control of movement of an asphalt compactor within a compacting area, the system comprising:
a vibratory system configured to compact an asphalt surface using force applied through one or both of a trailing drum and a leading drum;
a drive system configured to propel the asphalt compactor along a direction of travel;
one or more sensors configured to generate data indicative of operational criteria of the asphalt compactor, the one or more sensors including a grade sensor configured to determine a slope of the asphalt surface within the compacting area in at least the direction of travel of the asphalt compactor; and
a control system communicatively coupled to the one or more sensors, the control system configured to:
receive data indicative of the slope of the asphalt surface in at least the direction of travel of the asphalt compactor from the grade sensor,
determine if the slope of the asphalt surface is one of an incline slope or a decline slope in the direction of travel,
if the slope is determined to be the incline slope, determine if the incline slope exceeds a first threshold for the incline slope, and
if the incline slope exceeds the first threshold for the incline slope, control the vibratory system to stop vibration of the trailing drum.
