Constructor & Destructor Documentation

TrafficLight()

dsf::TrafficLight::TrafficLight ( Id id, Delay cycleTime )

inline

Construct a new TrafficLight object.

Parameters

id	The node's id
cycleTime	The node's cycle time

Member Function Documentation

cycles()

std::unordered_map< Id, std::unordered_map< Direction, TrafficLightCycle > > const & dsf::TrafficLight::cycles ( ) const

inline

Get the traffic light's cycles.

Returns

std::unordered_map<Id, std::unordered_map<Direction, TrafficLightCycle>> const& The traffic light's cycles

cycleTime()

Delay dsf::TrafficLight::cycleTime ( ) const

inline

Get the traffic light's total cycle time.

Returns

Delay The traffic light's cycle time

increasePhases()

void dsf::TrafficLight::increasePhases

(

Delay const

phase

)

Increase the phase times of the traffic light cycles.

Parameters

phase

Delay, the amount of time to increase the phase for each cycle

isGreen()

bool dsf::TrafficLight::isGreen	(	Id const	streetId,
		Direction	direction ) const

Returns true if the traffic light is green for a street and a direction.

Parameters

streetId	Id, the street's id
direction	Direction, the direction

Returns

true if the traffic light is green for the street and direction

isTrafficLight()

bool dsf::TrafficLight::isTrafficLight ( ) const

inlinevirtualnoexcept

Reimplemented from dsf::RoadJunction.

meanGreenTime()

double dsf::TrafficLight::meanGreenTime

(

bool

priorityStreets

)

const

Get the mean green time over every cycle.

Parameters

priorityStreets

bool, if true, only the priority streets are considered; if false, only the non-priority streets are considered

Returns

double The mean green time

The mean green time is the mean green time of all the cycles for the priority streets if priorityStreets is true, or for the non-priority streets if priorityStreets is false.

resetCycles()

void dsf::TrafficLight::resetCycles

(

)

Resets all traffic light cycles.

For more info, see TrafficLightCycle::reset()

setComplementaryCycle()

void dsf::TrafficLight::setComplementaryCycle	(	Id const	streetId,
		Id const	existingCycle )

Set the complementary cycle for a street.

Parameters

streetId	Id, The street's id
existingCycle	Id, The street's id associated with the existing cycle

Exceptions

std::invalid_argument	if the street id does not exist
std::invalid_argument	if the cycle does not exist

The complementary cycle is a cycle that has as green time the total cycle time minus the green time of the existing cycle. The phase is the total cycle time minus the green time of the existing cycle, plus the phase of the existing cycle.

setCycle()

void dsf::TrafficLight::setCycle	(	Id const	streetId,
		Direction	direction,
		TrafficLightCycle const &	cycle )

Set the cycle for a street and a direction.

Parameters

streetId	The street's id
direction	The direction
cycle	The traffic light cycle

setCycles()

void dsf::TrafficLight::setCycles ( std::unordered_map< Id, std::unordered_map< Direction, TrafficLightCycle > > cycles )

inline

Set the traffic light's cycles.

Parameters

cycles

std::unordered_map<Id, std::unordered_map<Direction, TrafficLightCycle>> The traffic light's cycles
