Make the crossings split level, then you would not need traffic lights at all. Just a couple of bridges or tunnels to aid cyclists and pedestrians crossing the access roads.
Then, maybe the bridge itself could be split level. Double decked, it would be twice as narrow and maybe even cheaper to build. And again no traffic lights would be needed.
