bicycleSafetyFactor

protected float bicycleSafetyFactor

bicycleSafetyWeight = length * bicycleSafetyFactor. For example, a 100m street with a safety factor of 2.0 will be considered in term of safety cost as the same as a 150m street with a safety factor of 1.0.

wayId

public long wayId

The OSM way ID from whence this came - needed to reference traffic data

Method Detail

canTraverse

public boolean canTraverse(TraverseModeSet modes)

Checks permissions of the street edge if specified modes are allowed to travel. Barriers aren't taken into account. So it can happen that canTraverse returns True. But doTraverse returns false. Since there are barriers on a street. This is because this function is used also on street when searching for start/stop. Those streets are then split. On splitted streets can be possible to drive with a CAR because it is only blocked from one way.

Parameters:

modes -

Returns:

canTraverseIncludingBarrier

public boolean canTraverseIncludingBarrier(TraverseMode mode)

This checks if start or end vertex is bollard If it is it creates intersection of street edge permissions and from/to barriers. Then it checks if mode is allowed to traverse the edge. By default CAR isn't allowed to traverse barrier but foot and bicycle are. This can be changed with different tags If start/end isn't bollard it just checks the street permissions. It is used in canTraverse(RoutingRequest, TraverseMode)

Parameters:

mode -

Returns:

getElevationProfile

public PackedCoordinateSequence getElevationProfile()

isElevationFlattened

public boolean isElevationFlattened()

getMaxSlope

public float getMaxSlope()

getDistance

public double getDistance()

Overrides:

getDistance in class Edge

traverse

public State traverse(State s0)

Description copied from class: Edge

Traverse this edge.

Specified by:

traverse in class Edge

Parameters:

s0 - The State coming into the edge.

Returns:

The State upon exiting the edge.

calculateSpeed

public double calculateSpeed(RoutingRequest options,
                             TraverseMode traverseMode,
                             long timeMillis)

Calculate the speed appropriately given the RoutingRequest and traverseMode and the current wall clock time. Note: this is not strictly symmetrical, because in a forward search we get the speed based on the time we enter this edge, whereas in a reverse search we get the speed based on the time we exit the edge.

weightLowerBound

public double weightLowerBound(RoutingRequest options)

Description copied from class: Edge

Returns a lower bound on edge weight given the routing options.

Overrides:

weightLowerBound in class Edge

Returns:

edge weight as a double.

Description copied from class: Edge

Returns a lower bound on traversal time given the routing options.

Overrides:

timeLowerBound in class Edge

Returns:

edge weight as a double.
