Why my player doesn't stop when it collide with the roadblock?,Collision does not work, player won't stop moving when it hit an object with collider.

So I had recently added this roadblock into my project, and I want to make the player stop when it touches or in other words collider, with the roadblocks. I have added rigidbody and collider to both objects(player and the roadblock. But when I run the game, it turns out that my player will just go through the roadblock even if I locked the roadblock's position on X Y Z and rotations. I just want to make the roadblock acting like a wall which prevents player from walking/running through. I used the transform method to move my player. Here is my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerMoving : MonoBehaviour
 {
     public float walkingspeed;
     public float runningspeed;
     public float crouchwalkingspeed;
     public float walkingstairsspeed;
     public Transform movingObject;
     public Animator anime;
     bool stair = false;
     // Update is called once per frame
     void FixedUpdate()
     {
         if (Input.GetKey("d"))
         {
             if (Input.GetKey("space"))
             {
                 movingObject.Translate(movingObject.right * -runningspeed * Time.deltaTime);
             }
             if (anime.GetBool("isCrouching") == true)
             {
                 movingObject.Translate(movingObject.right * -crouchwalkingspeed * Time.deltaTime);
             }
             if (stair == true)
             {
                 movingObject.Translate(movingObject.right * -walkingstairsspeed * Time.deltaTime);
                 stair = false;
             }
             else
             movingObject.Translate(movingObject.right * -walkingspeed * Time.deltaTime);
         }
         
         if (Input.GetKey("a"))
         {
             movingObject.Translate(movingObject.right * walkingspeed * Time.deltaTime);
         }
     }
     public void walkingOnStairs()
     {
             Debug.Log("im on stairs");
             stair = true;
     }
 }
 
 

Your help is extremely important for me.

Thank you!
