I'm sorry, could you elaborate? Do you mean because transgender people are so much more likely to be the victims of violent crimes?

I believe the reason the sign is highlighting women (all women) as opposed to specifically transgender women or people in general is that so few people are transgender,, that's the Canadian 2022 census because it actually included questions on gender, resulting in 0.33% of the population stating they identify with a gender other than that they were assigned at birth. Whereas women usually make up just over half the population, and have usually been made to feel unsafe by men (for example, 97% of women report being catcalled), without touching the rest of the violence against women, almost all of which is perpetrated by men.

If I'm off the mark I would love to hear your thoughts.
