Codeigniter URI routing with for multiple methods - codeigniter-2

Question

I am working on codeigniter. Controller name is "project" and 4 functions are there.."get_city_data", "get_store_data", "get_currency", "get_description".
Parameters I am passing in above 2 functions are - get_city_data($state, $city), get_place_data($state, $city, $store).
So on browser to render these functions I am using the urls respectively as-
http://localhost/project/get_city_data/state1/city1
I want to change the urls like
http://localhost/state1/city1
In routes.php if I define a route like this
$route['(:any)/(:any)'] = 'project/get_city_data/$1/$2' then it reflects for all other functions as well but I want to change urls for these 2 functions only.
Also I do not want to use _remap function as it doesn't go well with my needs.
Can anybody help me in this?
ThankYou

I suggest you to check in the database at first, then determine the routes required. Here is my answer for your requirement.
In your routes.php, try this code:
require_once( BASEPATH . 'database/DB' . EXT );
$url_source = $_SERVER['REDIRECT_URL'];
$arr_url = explode("/", $url_source);
$state_name = $arr_url[3];
$city_name = $arr_url[4];
$store_name = $arr_url[4];
$db = & DB();
//Let say grab 3 columns to be check
$db->select('state_name, city_name, store_name');
if(!empty($state_name)):
$db->where('state_name', $state_name);
endif;
if(!empty($city_name)):
$db->where('city_name', $city_name);
endif;
if(!empty($store_name)):
$db->where('store_name', $store_name);
endif;
$query = $db->get('table', 1);
$obj = $query->row();
if ($obj):
$route["$obj->state_name/$obj->city_name/$obj->store_name"] = "project/get_city_data/$state_name/$city_name/$store_name";
endif;
You can try by this url to test:
http://localhost/state_name/city_name/store_name

I got it solved using regex.
In routes.php i wrote
$url_source = $_SERVER['REQUEST_URI'];
if(!(preg_match('%^/project/get_description\?state=[a-zA-Z_-]*%', $url_source) || preg_match('%^/project/get_currency\?state=[a-zA-Z_-]*%', $url_source))){
if(!preg_match('%^\/[a-zA-Z_-]+\/[a-zA-Z_-]+\/[a-zA-Z_-]+$%', $url_source)){
$route['(:any)/(:any)'] = 'project/get_city_data/$1/$2';
}else{
$route['(:any)/(:any)/(:any)'] = 'project/get_store_data/$1/$2/$3';
}
}
This way I was able to route for particular functions.
