Here is a step-by-step guide to creating the procedure 'insertRoute' in SQL:

1. First, you need to declare the procedure. You can do this using the CREATE PROCEDURE statement. The procedure takes one parameter, route_name, which is of type VARCHAR.

```sql
CREATE PROCEDURE insertRoute(route_name VARCHAR)
```

2. Begin the body of the procedure with the BEGIN statement.

```sql
BEGIN
```

3. Declare a variable to hold the new route id. This variable will hold the count of the existing records in the route table plus 1. You can declare this variable using the DECLARE statement.

```sql
DECLARE @new_route_id INT;
```

4. Set the value of the new_route_id variable to the count of the existing records in the route table plus 1. You can do this using the SELECT statement and the COUNT function.

```sql
SELECT @new_route_id = COUNT(*) + 1 FROM route;
```

5. Insert the new route id and the route_name into the route table. You can do this using the INSERT INTO statement.

```sql
INSERT INTO route(route_id, route_name) VALUES (@new_route_id, route_name);
```

6. End the body of the procedure with the END statement.

```sql
END;
```

7. Finally, execute the procedure to create it.

Here is the complete procedure:

```sql
CREATE PROCEDURE insertRoute(@route_name VARCHAR)
AS
BEGIN
DECLARE @new_route_id INT;
SELECT @new_route_id = COUNT(*) + 1 FROM route;
INSERT INTO route(route_id, route_name) VALUES (@new_route_id, @route_name);
END;
```

Please note that this procedure assumes that the route_id column in the route table is of type INT and that it can accept new values generated by the procedure. If this is not the case, you may need to adjust the procedure accordingly.
