Certified mobility survey Cerema (EMC²) of the greater Toulouse area

The EMC² is a system implemented by the Cerema and is regularly updated to adapt to technological and societal changes. It has been in operation for about forty years and has already been used to more than 150 surveys in more than 100 territories. Its current version is modular and is based on a "core" survey and "and additional surveys. The "core" survey is based on a rigorous methodology interviewing by telephone or face-to-face of a random sample of households residing in the area on their characteristics and their travel practices. The complementary surveys allow the survey to be adapted to local issues while benefiting from a robust methodologyand results that can be compared with other areas.

The following are planned for theToulouse area :

• a "student" extension, who are traditionally under-represented in the core survey,

• a web-based questionnaire on on the potential of "cycling" as a mode of transportation,

• a module allowing the collection of itineraries with the help of a smartphone application.

The web questionnaire aims in particular to improve the conditions of mobility of two-wheelers, with the idea of allowing the development of a module for the Toulouse travel model. The itinerary collection module will also be a first at the national level also a first at the national level and will allow to better understand the recruitment bias of volunteers accepting to be to be geolocated during their trips to refine the travel habits during the week and to improve during the week and to improve knowledge of the energy energy balance and greenhouse gas emissions related to travel (actual journeys, including the search for a car park, speeds, etc.)
