Yeah, automotive traffic flow is the priority. There are two crosswalks in my neighbourhood that are unreasonably long.

Traffic control is the most statistically driven type of engineering. All my type A pals were drawn to it.
Municipalities regularly receive request to review the length of crossing signals - give it a try! Depending on where you live, you might get a really responsive answer!
Nope. Pedestrian foot traffic needs to be completely separated from vehicular traffic. I utterly detest all city infrastructure where you only have one level of mixed traffic.
