Here on Streets.MN, much has been discussed about pedestrian crossings, signage, and traffic signals on the Green Line. Because of this, it may be useful to look at what our European peers are doing. This urban railway in Slovakia is more of a tramway, but as you can see it has some dedicated right of way in places.
Note how the train interacts with people and vehicles with a near complete lack of signage and traffic signals. Try to ignore the guy surfing the tracks on a pallet.
