Aircraft X assigned the KNIK2 SID began left turn at 4.3 DME at 2;300 MSL and the system immediately responded with a low altitude notification. I issued a low altitude alert with an immediate climb and left turn. The aircraft responded in the affirmative and advised terrain in sight. At the TED 057 radial 7.3 DME; Aircraft X entered a lower MVA. I advised the aircraft of the MVA change and issued a normal rate of climb. I believe adding a 'do not penetrate' DME arc about the TED VOR; and incorporating into a new KNIK3 SID; would solve a lot of the issues with our SID. The wording in the notes does not seem to be properly interpreted by the auto pilots; and is being misread or unnoticed by the PICs. A graphically depicted DME arc about the TED DME should be easier for the Flight Director to digest; while providing a visual queue to the PIC that an important restriction exists. I also suggest terrain depictions to be overlaid onto the plate in order to convey the importance of the restrictions by clearly displaying the proximity of the topographical challenge.
A11 TRACON controller reported air carrier on KNIK2 SID entered higher MVA resulting in low altitude alert.
