> We need to look further at the cause, which is highway and road design, in addition to the symptoms, which are dangerous driver behaviors. You can address the symptoms, but as long as the cause is still relevant, the symptoms will persist. I watch a lot of dash cam footage and probably the most common cause of crashes related to poor road design are poorly timed traffic light changes when dealing with an unprotected green. Imagine a typical 4-way intersection with traffic lights. All lanes coming from east/west are red. Lanes going north/south are green, with the left turns having an unprotected green. A car is traveling north and is turning left. They've entered the intersection, but are waiting for cars traveling straight south. Then, ALL AT ONCE, the green lights turn yellow. What happens so often? A southbound car guns it to beat their yellow. Meanwhile, the person that was turning left guns it as well to beat THEIR yellow. Boom, you've got a crash. If they were to change the traffic light cycle so that the lanes going straight went yellow and then red FIRST, wait a second, and THEN make the left-turn lanes go yellow and then red, these types of crashes could be significantly reduced.
