Are you travelling outside the boundaries of the town you live in? If so, according to my friends who follow the Hanafi mazhab, the moment you leave the boundaries of your town, you are considered a musafir and therefor can aggregate your solat. What you can do is go outside the boundary of your town, perform solat zuhri as a musafir and on your way home, stop outside the boundary of your town and perform the maghrib and isha solat together as a musafir. This is told to me by my friends. Please consult a real life ustaz to get a more accurate answer.
