Very dangerous tree

This tree is hugely dangerous! It’s on the Sandringham and Banbury lane junction. I have to walk my children past this tree twice a day. Today a huge piece fell off just in front of my 5 year old, this could have been life threatening. Photo of piece attached. We have no other way to walk but under it and every time bits fall off. Surely it needs cutting back and making it safer for everyone. There is also a huge limb that is broken and clearly logged in the middle of the tree which is just waiting to fall especially in windy conditions. I have been taking lots of photos incase anything happens to people so can prove that it’s dangerous.
