Magento2 – How to Get Current Address Data in Custom Shipping Method

If the shipping method is estimated on the cart page or checkout page, you should be able to get the title of the shipping method with: Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress()->getShippingDescription(); Please keep in mind that this will return an empty string if it wasn't chosen on the cart page or checkout.

I added the title on top of the cart. in app/design/frontend/rwd/default/template/checkout/cart.phtml

echo "<pre>" . Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress()->getShippingDescription() . "</pre><br />";

The solution es this: First I created a helper to manage the options (shipping methods) And then use it in the Model.

Helper:

namespace TCK\ASM\Helper;

use Magento\Framework\App\Helper\AbstractHelper;
use TCK\ASM\Model\Source\Method;

/**
 * Class Group
 * @package TCK\ASM\Helper
 */

    class Group extends AbstractHelper

{
    protected $resourceConnection;
    protected $asm;

    public function __construct(
        \Magento\Framework\App\ResourceConnection $resourceConnection,
        \TCK\ASM\Model\Source\Method $asm
    )
    {
        $this->resourceConnection = $resourceConnection;
        $this->asm = $asm;
    }
    /**
     * Stub
     * @return string
     */
    public function getGroupData($id)
    {

        $db = $this->resourceConnection->getConnection();
        $result = $db->query('SELECT * FROM customer_group WHERE customer_group_id=' . $id); 
        $row = $result->fetch();
        $values=$row['shipping_method'];
        $split=explode(",",$values);
        $count = count($split);

        $metodos=$this->asm->toOptionArray();

        $i=1;
        $s=0;
        for ($i; $i <= $count; $i++) {
            $info[$i]=$metodos[$split[$s]];
            $s++;
        }

        return $info;
    }

    public function getAllMethods()
    {
        $metodos=$this->asm->toOptionArray();

        return $metodos;
    }
}

Model:

namespace TCK\ASM\Model\Carrier;

use Magento\Quote\Model\Quote\Address\RateRequest;
use Magento\Shipping\Model\Rate\Result;
