Lack of road signs/markings

Clearly there is a lack of road markings or signs, as in the space of a week I’ve had 3 cars drive straight towards me going the wrong way on Shelley Street. Entering from Kingsley park terrace onto Shelley street, which is one way (the other way to what people are going) This is unsafe as there is limited spaces available usually to pull aside and cars coming at you head on isn’t great
