Description

The French Ministry in charge of ecology and sustainable development carries out a survey on urban public transport since 1995, in partnership with the GART (Groupement des Autorités Responsables de Transport – French Association of Public Transport Authorities) and the UTP (Union des Transports Publics et Ferroviaires – French Public Transport Union). This survey is led with urban public transport proper authorities and operators.

Abstract

Background
The French Ministry in charge of ecology and sustainable development carries out a survey on urban public transport since 1995, in partnership with the GART (Groupement des Autorités Responsables de Transport – French Association of Public Transport Authorities) and the UTP (Union des Transports Publics et Ferroviaires – French Public Transport Union). This survey is led with urban public transport proper authorities and operators.

It gathers financial, supply and demand data, which are released every year in a database called "base TCU". Urban public transport networks can be described and compared by these data. The comparisons are mainly made from direct interpretations of a range of variables (simple tabulations or cross-tabulations). They show some large disparities in commercial and financial efficiencies although networks are similar in served population size.


Aims of the study
Some relations between the "base TCU" variables have an effect on the network classes depending on the served population size. The paper proposes a summarized description of the overall "base TCU" variables. The description is based on the analysis of the relations between the "base TCU" variables and the building of synthetical variables which discriminate urban public transport networks. The main synthetical variables identified characterize the size of the network, the possible high-quality transport mode in operation and the spatial dispersal of the network.

A typology of urban public transport networks is proposed then by grouping the most similar networks together. Five classes are identified:
• the small networks,
• the medium networks without dedicated-lane public transport,
• the medium networks with dedicated-lane public transport,
• the big networks with tramway lanes,
• the big networks with metro lanes.

Finally the paper provides econometric models to explain in part the disparities observed on two aspects:
• the commercial efficiency, which is based on the annual number of travels on the urban public transport networks (per inhabitant);
• the financial efficiency, which is assessed by the net public operating loss for the urban public transport networks (per inhabitant).

Several models are proposed in order to take into account the previous typology.
