pub struct ControlTrafficSignal {
    pub id: IntersectionID,
    pub stages: Vec<Stage>,
    pub offset: Duration,
}
Expand description

A traffic signal consists of a sequence of Stages that repeat in a cycle. Most Stages last for a fixed duration. During a single Stage, some movements are protected (can proceed with the highest priority), while others are permitted (have to yield before proceeding).

Implementations§

source§

impl ControlTrafficSignal

source

pub fn new(map: &Map, id: IntersectionID) -> ControlTrafficSignal

source

pub fn get_possible_policies( map: &Map, id: IntersectionID ) -> Vec<(String, ControlTrafficSignal)>

source

pub fn get_min_crossing_time(&self, idx: usize, i: &Intersection) -> Duration

source

pub fn validate(&self, i: &Intersection) -> Result<()>

source

pub fn convert_to_ped_scramble(&mut self, i: &Intersection) -> bool

Move crosswalks from stages, adding them to an all-walk as last stage. This may promote yields to protected. True is returned if any stages were added or modified.

source

pub fn convert_to_ped_scramble_without_promotion( &mut self, i: &Intersection ) -> bool

Move crosswalks from stages, adding them to an all-walk as last stage. This does not promote yields to protected. True is returned if any stages were added or modified.

source

fn internal_convert_to_ped_scramble( &mut self, promote_yield_to_protected: bool, i: &Intersection ) -> bool

source

pub fn adjust_major_minor_timing( &mut self, major: Duration, minor: Duration, map: &Map ) -> Result<()>

Modifies the fixed timing of all stages, applying either a major or minor duration, depending on the relative rank of the roads involved in the intersection. If this transformation couldn’t be applied, returns an error. Even if an error is returned, the signal may have been changed – so only call this on a cloned signal.

source

pub fn missing_turns(&self, i: &Intersection) -> BTreeSet<MovementID>

source

pub fn simple_cycle_duration(&self) -> Duration

How long a full cycle of the signal lasts, assuming no actuated timings.
