      abstract = {Research on the demand side of public transportation  systems with the use of time series data frequently shows  conflicting results with respect to fare elasticities and  the factors affecting it. In this analysis we complement  prior research by developing seemingly unrelated regression  equation models with monthly data for a city served by  three different modes of public transportation. The results  indicate that, as expected, urban public transport demand  in Athens, Greece, is inelastic with respect to fares but,  surprisingly, highly inelastic with respect to automobile  fuel cost. Further, different transit modes have  significantly different fare elasticities, a finding with  important practical implications.},
