Function map_model::make::traffic_signals::get_possible_policies

pub fn get_possible_policies(
    map: &Map, 
    id: IntersectionID, 
    timer: &mut Timer<'_>
) -> Vec<(String, ControlTrafficSignal)>

Applies a bunch of heuristics to a single intersection, returning the valid results in best-first order. The signal configuration is only based on the roads connected to the intersection.
