Teaching/research job in any University (in a research oriented department or teaching-oriented department) DOES NOT require a lot of travel. Invitations to conferences or seminar talks come indeed but this does not mean you have to go, if you don't want to. Traveling to two conferences per year (usually one week or less) and/or 1-2 seminar talks per year (for one day) will be sufficient. Even if you do not travel at all, this is not going to hurt seriously your research career. People travel a lot because they like to travel:-)
