The financing of urban public transport in France is based on the principle of contributions from the direct and indirect beneficiaries of these services. Users/customers, companies and public authorities are therefore called upon to finance them in the form of commercial revenues, mobility payments and public subsidies. It will be necessary to assess the effects of urban public transport on the value of land and housing, and whether one source of funding might lie in a possible capitalisation in land and walls of the gains in accessibility made possible by public transport. The academic work carried out over several years using econometric tools in particular will provide some answers to this question.
