Here's a script which will convert the URL to an ITN:
<?

function gmapToItn($url, & $errors)

isset($parts['query']))) {
$errors[] = 'Invalid URL.';
$ok = false;
} else {
parse_str($parts['query'], $params);
$query = '';
$saddr = isset($params['saddr']) ?
trim($params['saddr']) : '';
if ($saddr == '') {
$errors[] = 'Parameter \'saddr\' not specified.';
$ok = false;
} else {
$query .= $saddr;
$daddr = isset($params['daddr']) ?
trim($params['daddr']) : '';
if ($daddr != '') {
if ($query != '') $query .= ' to:';
$query .= $daddr;
}
}
}
if ($ok) {
$route = array();
$locs = explode('to:', $query);
foreach ($locs as $loc) {
$ptn = '/^\s*([\+-]?\d+(?:.\d+)?)' .
'\s*,\s*([\+-]?\d+(?:.\d+)?)\s*$/';

if (!preg_match($ptn, $loc, $m)) {
$errors[] = "No coordinates specified for " .
"location \"$loc\".";
$ok = false;
} else {
// String like 'Stationsstraat @50.879940, 4.092990'

}
}
}
}
// Create ITN
