Detailed Description

This class generically implements the TrafficRules class in the sense of the tagging specification. It is designed to make sense for most countries and participants. Country specific details (traffic signs, speed limits regulations, ...) must be implemented by inheriting classes.

Member Function Documentation

◆ canChangeLane()

bool lanelet::traffic_rules::GenericTrafficRules::canChangeLane	(	const ConstLanelet &	from,
		const ConstLanelet &	to
	)		const

overridevirtual

determines if a lane change can be made between two lanelets

The orientation of the lanelets is important here as well.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 248 of file GenericTrafficRules.cpp.

◆ canPass() [1/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass ( const ConstArea & area ) const

overridevirtual

returns whether it is allowed to pass/drive on this area

Implements lanelet::traffic_rules::TrafficRules.

Reimplemented in lanelet::traffic_rules::GermanVehicle.

Definition at line 149 of file GenericTrafficRules.cpp.

◆ canPass() [2/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass	(	const ConstArea &	from,
		const ConstArea &	to
	)		const

overridevirtual

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 237 of file GenericTrafficRules.cpp.

◆ canPass() [3/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass	(	const ConstArea &	from,
		const ConstLanelet &	to
	)		const

overridevirtual

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 220 of file GenericTrafficRules.cpp.

◆ canPass() [4/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass	(	const ConstLanelet &	from,
		const ConstArea &	to
	)		const

overridevirtual

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 203 of file GenericTrafficRules.cpp.

◆ canPass() [5/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass	(	const ConstLanelet &	from,
		const ConstLanelet &	to
	)		const

overridevirtual

returns whether it is allowed to pass/drive from a lanelet to another lanelet.

The orientation of the lanelets is important. The function first checks if lanelets are direcly adjacent, then checks if both lanelets are passable and finally checks if any traffic rule prevents to pass between the lanelets.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 187 of file GenericTrafficRules.cpp.

◆ canPass() [6/8]

bool lanelet::traffic_rules::GenericTrafficRules::canPass ( const ConstLanelet & lanelet ) const

overridevirtual

returns whether it is allowed to pass/drive on this lanelet

The result can differ by the type of the traffic participant. A sidewalk lanelet is passable for a pedestrian but not for a vehicle. Orientation is important. It is not possible to pass an inverted oneWay Lanelet.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 133 of file GenericTrafficRules.cpp.

◆ canPass() [7/8]

virtual Optional<bool> lanelet::traffic_rules::GenericTrafficRules::canPass ( const RegulatoryElementConstPtrs & regElems ) const

protectedpure virtual

Called by canPass to check if traffic rules make a certain primitive drivable/not drivable If the optional is empty, there is no traffic rule that determines this.

Implemented in lanelet::traffic_rules::GermanBicycle, lanelet::traffic_rules::GermanPedestrian, and lanelet::traffic_rules::GermanVehicle.

◆ canPass() [8/8]

Optional< bool > lanelet::traffic_rules::GenericTrafficRules::canPass	(	const std::string &	type,
		const std::string &
	)		const

protectedvirtual

Called by canPass to check if a certain lanelet type is drivable for this participant.

Definition at line 327 of file GenericTrafficRules.cpp.

◆ countrySpeedLimits()

virtual const CountrySpeedLimits& lanelet::traffic_rules::GenericTrafficRules::countrySpeedLimits ( ) const

protectedpure virtual

Overloads should return a descripton of their countrie's speed limit definition.

Implemented in lanelet::traffic_rules::GermanBicycle, lanelet::traffic_rules::GermanPedestrian, and lanelet::traffic_rules::GermanVehicle.

◆ hasDynamicRules()

bool lanelet::traffic_rules::GenericTrafficRules::hasDynamicRules ( const ConstLanelet & lanelet ) const

overridevirtual

returns whether dynamic traffic rules apply to this lanelet.

This can be a case if e.g. a speed limit is controlled by digital signs. If this returns true, additional handling must be done to find which rules are dynamic and how to handle them. This makes the values returned by the other functions unreliable. Handling of dynamic rules is not covered here.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 127 of file GenericTrafficRules.cpp.

◆ isOneWay()

bool lanelet::traffic_rules::GenericTrafficRules::isOneWay ( const ConstLanelet & lanelet ) const

overridevirtual

returns whether a lanelet can be driven in one direction only

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 350 of file GenericTrafficRules.cpp.

◆ laneChangeType()

LaneChangeType lanelet::traffic_rules::GenericTrafficRules::laneChangeType	(	const ConstLineString3d &	boundary,
		bool	virtualIsPassable = `false`
	)		const

protectedvirtual

checks which types of lange changes are allowed along this boundary to make a lane switch from one lanelet to another.

Definition at line 161 of file GenericTrafficRules.cpp.

◆ speedLimit() [1/4]

SpeedLimitInformation lanelet::traffic_rules::GenericTrafficRules::speedLimit ( const ConstArea & area ) const

overridevirtual

returns speed limit on this area.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 319 of file GenericTrafficRules.cpp.

◆ speedLimit() [2/4]

SpeedLimitInformation lanelet::traffic_rules::GenericTrafficRules::speedLimit ( const ConstLanelet & lanelet ) const

overridevirtual

returns speed limit on this lanelet.

Implements lanelet::traffic_rules::TrafficRules.

Definition at line 315 of file GenericTrafficRules.cpp.

◆ speedLimit() [3/4]

virtual Optional<SpeedLimitInformation> lanelet::traffic_rules::GenericTrafficRules::speedLimit ( const RegulatoryElementConstPtrs & regelems ) const

protectedpure virtual

Returns speed limit as defined by regiualtory elements if present.

Implemented in lanelet::traffic_rules::GermanVehicle, lanelet::traffic_rules::GermanBicycle, and lanelet::traffic_rules::GermanPedestrian.

◆ speedLimit() [4/4]

SpeedLimitInformation lanelet::traffic_rules::GenericTrafficRules::speedLimit	(	const RegulatoryElementConstPtrs &	regelems,
		const AttributeMap &	attributes
	)		const

private

◆ TrafficRules()

lanelet::traffic_rules::TrafficRules::TrafficRules

inlineexplicit

Constructor.

Parameters

config a configuration for traffic rules. This can be necessary for very specialized rule objects (ie considering the time of day or the weather). The config must have at least two entries: participant and location.
