org.opentripplanner.graph_builder.impl.shapefile.CaseBasedTraversalPermissionConverter

Calculates street traversal permissions based upon a fixed set of cases. For example, given a shapefile that includes a DIRECTION column with data as follows:

 | DIRECTION | NAME    |  | ONE_WAY_F | Side St |  | TWO_WAY   | Main St | | ONE_WAY_B | Foo St. |

You could use a CaseBasedTraversalPermissionConverter to implement the following rules:

By default, all streets should be traversable by pedestrians and bicycles in both directions.

If a street's DIRECTION attribute is ONE_WAY_F, it should be traversable by cars and bikes in only the forward direction and traversable by pedestrians in both directions.

If a street's DIRECTION attribute is ONE_WAY_B, it should be traversable by cars and bikes in only the backward direction and traversable by pedestrians in both directions.

If a street's DIRECTION attribute is TWO_WAY, it should be traversable by everyone in both directions.

These rules could be implemented by configuring the converter bean as follows:

 {@code                     }

@see org.opentripplanner.routing.edgetype.StreetTraversalPermission

        builder.setFeatureSourceFactory(factory);
        ShapefileStreetSchema schema = new ShapefileStreetSchema();
        schema.setIdAttribute("LOCALID");
        schema.setNameAttribute("FULL_NAME");


        CaseBasedTraversalPermissionConverter perms = new CaseBasedTraversalPermissionConverter(
                "DIRECTION", StreetTraversalPermission.PEDESTRIAN_AND_BICYCLE);


        perms.addPermission("2", StreetTraversalPermission.ALL,
                StreetTraversalPermission.PEDESTRIAN);
        perms.addPermission("3", StreetTraversalPermission.PEDESTRIAN,
                StreetTraversalPermission.ALL);
        perms.addPermission("1", StreetTraversalPermission.ALL, StreetTraversalPermission.ALL);


        schema.setPermissionConverter(perms);


        // as a test, use prefixes ("NE", SE", etc) as an alert
        schema.setNoteConverter(new AttributeFeatureConverter<String>("PREFIX"));
