Sample Data - pgRouting Manual (3.0)
Sample Data
The documentation provides very simple example queries based on a small sample network. To be able to execute the sample queries, run the following SQL commands to create a table with a small network data set.
Create table
CREATE TABLE edge_table (
id BIGSERIAL,
dir character varying,
source BIGINT,
target BIGINT,
cost FLOAT,
reverse_cost FLOAT,
capacity BIGINT,
reverse_capacity BIGINT,
category_id INTEGER,
reverse_category_id INTEGER,
x1 FLOAT,
y1 FLOAT,
x2 FLOAT,
y2 FLOAT,
the_geom geometry
);
Insert data
INSERT INTO edge_table (
category_id, reverse_category_id,
cost, reverse_cost,
capacity, reverse_capacity,
x1, y1,
x2, y2) VALUES
(3, 1, 1, 1, 80, 130, 2, 0, 2, 1),
(3, 2, -1, 1, -1, 100, 2, 1, 3, 1),
(2, 1, -1, 1, -1, 130, 3, 1, 4, 1),
(2, 4, 1, 1, 100, 50, 2, 1, 2, 2),
(1, 4, 1, -1, 130, -1, 3, 1, 3, 2),
(4, 2, 1, 1, 50, 100, 0, 2, 1, 2),
(4, 1, 1, 1, 50, 130, 1, 2, 2, 2),
(2, 1, 1, 1, 100, 130, 2, 2, 3, 2),
(1, 3, 1, 1, 130, 80, 3, 2, 4, 2),
(1, 4, 1, 1, 130, 50, 2, 2, 2, 3),
(1, 2, 1, -1, 130, -1, 3, 2, 3, 3),
(2, 3, 1, -1, 100, -1, 2, 3, 3, 3),
(2, 4, 1, -1, 100, -1, 3, 3, 4, 3),
(3, 1, 1, 1, 80, 130, 2, 3, 2, 4),
(3, 4, 1, 1, 80, 50, 4, 2, 4, 3),
(3, 3, 1, 1, 80, 80, 4, 1, 4, 2),
(1, 2, 1, 1, 130, 100, 0.5, 3.5, 1.999999999999,3.5),
(4, 1, 1, 1, 50, 130, 3.5, 2.3, 3.5,4);
Updating geometry
UPDATE edge_table SET the_geom = st_makeline(st_point(x1,y1),st_point(x2,y2)),
dir = CASE WHEN (cost>0 AND reverse_cost>0) THEN 'B' -- both ways
WHEN (cost>0 AND reverse_cost<0) THEN 'FT' -- direction of the LINESSTRING
WHEN (cost<0 AND reverse_cost>0) THEN 'TF' -- reverse direction of the LINESTRING
ELSE '' END; -- unknown
Topology
-
Before you test a routing function use this query to create a topology (fills the
sourceandtargetcolumns).
SELECT pgr_createTopology('edge_table',0.001);
Points of interest
-
When points outside of the graph.
-
Used with the withPoints - Family of functions functions.
CREATE TABLE pointsOfInterest(
pid BIGSERIAL,
x FLOAT,
y FLOAT,
edge_id BIGINT,
side CHAR,
fraction FLOAT,
the_geom geometry,
newPoint geometry
);
INSERT INTO pointsOfInterest (x, y, edge_id, side, fraction) VALUES
(1.8, 0.4, 1, 'l', 0.4),
(4.2, 2.4, 15, 'r', 0.4),
(2.6, 3.2, 12, 'l', 0.6),
(0.3, 1.8, 6, 'r', 0.3),
(2.9, 1.8, 5, 'l', 0.8),
(2.2, 1.7, 4, 'b', 0.7);
UPDATE pointsOfInterest SET the_geom = st_makePoint(x,y);
UPDATE pointsOfInterest
SET newPoint = ST_LineInterpolatePoint(e.the_geom, fraction)
FROM edge_table AS e WHERE edge_id = id;
Restrictions
-
Used with the pgr_trsp - Turn Restriction Shortest Path (TRSP) functions.
CREATE TABLE restrictions (
rid BIGINT NOT NULL,
to_cost FLOAT,
target_id BIGINT,
from_edge BIGINT,
via_path TEXT
);
INSERT INTO restrictions (rid, to_cost, target_id, from_edge, via_path) VALUES
(1, 100, 7, 4, NULL),
(1, 100, 11, 8, NULL),
(1, 100, 10, 7, NULL),
(2, 4, 8, 3, 5),
(3, 100, 9, 16, NULL);
CREATE TABLE new_restrictions (
id SERIAL PRIMARY KEY,
path BIGINT[],
cost float
);
INSERT INTO new_restrictions (path, cost) VALUES
(ARRAY[4, 7], 100),
(ARRAY[8, 11], 100),
(ARRAY[4, 8], 100),
(ARRAY[5, 9], 100),
(ARRAY[10, 12], 100),
(ARRAY[9, 15], 100),
(ARRAY[3, 5, 8], 100);
Images
-
Red arrows correspond when
cost> 0 in the edge table. -
Blue arrows correspond when
reverse_cost> 0 in the edge table. -
Points are outside the graph.

Network for queries marked as
directed
and
cost
and
reverse_cost
columns are used
When working with city networks, this is recommended for point of view of vehicles.
Network for queries marked as
undirected
and
cost
and
reverse_cost
columns are used
When working with city networks, this is recommended for point of view of pedestrians.

opentime INTEGER,
