In this paper, we build a proxy cost model for tramway services. we estimate separately: (i) transport services production costs; (ii) infrastructure costs; (iii) maintenance costs; (iv) administrative and general costs and (v) the cost of capital. we apply the proposed methodology to estimate the standard cost of italian tramway services. detailed data about costs, technical and environmental characteristics were collected by means of questionnaires sent to italian companies providing 100% of tramway services in 2012.

We develop a hybrid cost model for the determination of unit standard costs in the Italian local public bus transport sector. Detailed economic and transport data have been collected from companies producing more than 500 million of bus-kilometers in Italy observed in 2011. We draw upon the Bottom-Up approach for the estimation of the cost of the driving personnel and the economic cost of the rolling stock which usually cover more than 50% of the total economic cost.
