  • Field Details

    • LANE_ADD_EVENT

      public static final EventType LANE_ADD_EVENT
      The (regular, not timed) event type for pub/sub indicating the addition of a Lane to a CrossSectionLink.
      Payload: Object[] { String networkId, String linkId, String LaneId, int laneNumber }
      TODO work in a different way with lane numbers to align to standard lane numbering.

    • LANE_REMOVE_EVENT

      public static final EventType LANE_REMOVE_EVENT
      The (regular, not timed) event type for pub/sub indicating the removal of a Lane from a CrossSectionLink.
      Payload: Object[] { String networkId, String linkId, String LaneId }
      TODO allow for the removal of a Lane; currently this is not possible.

  • Constructor Details

    • CrossSectionLink

      public CrossSectionLink(RoadNetwork network, String id, Node startNode, Node endNode, LinkType linkType, OtsLine2d designLine, ContinuousPiecewiseLinearFunction elevation, LaneKeepingPolicy laneKeepingPolicy) throws NetworkException
      Construction of a cross section link.
      Parameters:
      network - the network
      id - the link id.
      startNode - the start node (directional).
      endNode - the end node (directional).
      linkType - the link type
      designLine - the design line of the Link
      elevation - elevation given over fractional length, may be null.
      laneKeepingPolicy - the policy to generally keep left, keep right, or keep lane
      Throws:
      NetworkException - if link already exists in the network, if name of the link is not unique, or if the start node or the end node of the link are not registered in the network.
