Certainly, if safety was the only concern, the best course of action would be to end the illegal occupation and settlement of the area. There sort of measures likely serve as a means to demoralise the Palestinians, and remind them of their status as second-class citizens. Maybe they've saved a few Israeli settlers, too. Sure, it's bad for PR, but that hasn't exactly been Israel's strong suit lately. Think of all the crazy things Netanyahu has said during the last election.
