Your table isnt properly stable , other than that you would need to fix some stuff around or upated it for it to work.
I'll make your life simple . Delet the transport_data table , and copy and paste whats bellow here into notpad and save it as an .sql and than execute it and you should be fine.
Code:
CREATE TABLE `transport_data` (
`entry` int(10) unsigned NOT NULL default '0',
`name` text character set utf8 collate utf8_unicode_ci,
`period` int(10) unsigned NOT NULL default '0',
PRIMARY KEY (`entry`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT='World System';
INSERT INTO `transport_data` VALUES ('181646', 'Azuremyst and Auberdine', '251162');
INSERT INTO `transport_data` VALUES ('176495', 'Grom\'Gol Base Camp and Undercity', '333044');
INSERT INTO `transport_data` VALUES ('177233', 'Forgotton Coast and Feathermoon Stronghold', '317040');
INSERT INTO `transport_data` VALUES ('176310', 'Menethil Harbor and Auberdine', '261004');
INSERT INTO `transport_data` VALUES ('176231', 'Menethil Harbor and Theramore Isle', '282824');
INSERT INTO `transport_data` VALUES ('176244', 'Teldrassil and Auberdine', '309295');
INSERT INTO `transport_data` VALUES ('175080', 'Grom\'Gol Base Camp and Orgrimmar', '303463');
INSERT INTO `transport_data` VALUES ('164871', 'Orgrimmar and Undercity', '356284');
INSERT INTO `transport_data` VALUES ('20808', 'Ratchet and Booty Bay', '350818');
