ABSTRACT
Against the backdrop of extensive urban expansion and suburbanization (Chen 2000; Crawford 1994; Haddon 2001; Hall 1989; Thorns 1972) telephony is seen as a way to coordinate interaction (Katz 1999). However, there are also a number of claims about the potential effects that telecommunications can have on mobility (Katz 2001). For example, there is the suggestion that telephony and transportation stimulate each other (Falk and Abler 1980). Others argue that telephony modifies travel rather than reducing demand (Salomon 1985), and still others note the contrary idea that telephony replaces transportation (Claisse and Rowe 1993; 1988).
