Roundabouts would help too. There's a lot of random traffic light controlled junctions in lower traffic spots all over the place that could easily be replaced by a roundabout without any lights. Even where lights are involved, roundabouts drastically change the types of accidents experienced to the less-deadly rear-ends instead of t-bones (while also reducing the overall number of accidents too)
