National Transport and Travel Survey (2007-2008) / ENTD
Présentation de l'opération
Organisme producteur :
Insee. Direction des statistiques démographiques et sociales (DSDS)
Office of Economics, Statistics and Forecasting (SESP) of the Ministry for Transport
Type d'opération :
The 2007-2008 National Transport and Travel Survey was jointly conducted with the SESP, which has since become the Observation and Statistics Service (SOeS) of the Ministry for Ecology, Sustainable Development, Transport and housing - (MEDDTL). Its purpose is to obtain knowledge of the journeys undertaken by households residing in Metropolitan France and their use of both public and private transportation, in addition to information about the stock of vehicles possessed by households and their use. It forms part of the continuation of previous Transport surveys. These are the only surveys of mobility undertaken on this scale which describe all journeys, regardless of their length, duration, modes of transport, time of year, time of day or the reason for the journey. In order to understand these behaviours, the surveys also examine the opportunities for access to public transport and the means of private transport possessed by the households. The Transport and Travel Survey is the only source that provides a measurement of changes in peri-urban behaviours, which are becoming increasingly prevalent in urban mobility. It also allows for comparisons with previous surveys over time, with surveys conducted at the local level, and in space, with surveys conducted in other countries. This knowledge is also important for environmental issues (local or global pollutant emissions and energy consumption).
Thèmes abordés :
The topics covered are the journeys over short and long distances covered by households and their members, according to the different modes of transport used, in addition to the stock of vehicles possessed by households.
Champ de l'opération
Champ géographique :
Metropolitan France Regional extensions concern the Bretagne, Languedoc-Roussillon, Pays de Loire, Midi-Pyrénées and Île-de-France regions.
Unité statistique enquêtée :
"Ordinary" households, i.e. excluding households living in collective residence (hostels, prisons, hospitals, etc.) and in mobile dwellings (boatmen, homeless people, etc.)
Périodicité de l'opération :
Aperiodic, approximately every 10 years
Période et mode de collecte :
Data collection was carried out in face-to-face interviews using the computer-assisted method (CAPI), during two visits from the end of April 2007 to April 2008. It was spread over twelve months in order to take account of the seasonality that characterises mobility.
The 2007-2008 National Transport and Travel Survey is the fifth in the series of Transport surveys conducted in France since the 1960s (1966-1967, 1973-1974, 1981-1982 and 1993-1994). The survey carried out in 1993-1994 observed competition between modes of transport, their specialisation according to reasons, the combination of modes of transport to make the same journey, the influence of mobility and the possession of private vehicles on energy consumption and environmental concerns.
Plan de sondage :
"Ordinary" households in Metropolitan France are surveyed: of the 20,220 households surveyed, 10,700 concern the national sample and the rest cover regional extensions carried out in Île-de-France, Pays de Loire, Bretagne, Languedoc-Roussillon and Midi-Pyrénées.
At national level, a non-representative sub-sample of approximately 1,000 voluntary persons was established in order to test an experimental data collection method via GPS. These people were equipped with a GPS system for one week, which recorded "GPS traces" during the course of their journeys. This tracking firstly aims to correct the omission of certain journeys and to provide more accurate information about departure times and transport times. Secondly, it also provides information that cannot be obtained by traditional methods (very short journeys and terminal routes, waiting times, speed, choice of route, etc.).
Autres spécifications :
The Observation and Statistics Service (SOeS) now includes: - The Energy Observatory - French Environment Institute (IFEN) - Office of Economics, Statistics and Forecasting (SESP). Attached to the General Commission for Sustainable Development, the SOeS has been providing statistical services for the environment, energy, construction, housing and transport fields since 10 July 2008.
