This paper presents the methodology and first results of a survey focusing on mobility impairment in Paris region, with both quantitative results on impaired population and its mobility patterns and a qualitative appreciation of the accessibility.


In 2005, French Parliament voted a law to reach an equality of rights for disabled people, including responsibility for public authorities to grant accessibility for all both in public transport and public areas.

STIF, the public transport authority in the Paris region elaborated in 2008 a regional master plan for accessibility in public transport which is currently under implementation. In the meantime, municipalities in charge of measures concerning public areas have also started the necessary works.
It is now time to assess the impact of the on-going achievements on the mobility of impaired people. However, it appears that there is a lack of quantitative information to appreciate the current situation and the progress made.

Standard mobility surveys are inadequate for providing an overall description of impairment and impaired mobility. In the meantime, surveys focusing on health and disability are too general to describe everyday mobility.
In order to cope with this lack of information, STIF launched a regional survey on impaired mobility in 2013. The survey has three main objectives:
• Identifying the part of the general population suffering from impaired mobility: disabled persons (including their type of impairment) and persons suffering for temporary impairment (pregnant women, injured people, people with young children or travelling with luggage...);
• Comparing daily mobility behaviour of disabled people with the general population;
• Assessing the perception of accessibility of the different modes and of the measures which have been recently implemented in general and among people suffering from mobility impairment.

To identify the part of the regional population suffering from mobility impairment, a representative sample of 15,700 individuals will be interviewed using a specific algorithm to detect both administratively recognised handicaps and those which are not but have negative consequences on everyday life.
A subsample of 1,500 disabled people and 3,000 non-disabled people will additionally answer questions regarding their opinion on accessibility for all transport modes (car driving, public transport, walking).
Another subsample of 1,500 disabled people and 1,200 non-disabled people will describe all trips made the day before the interview as in usual household surveys.

The methodology is based on a telephone interview of a representative sample chosen at random as it is the only way to guarantee the accuracy of the quantification of the target population. The large subsample of disabled-people ensures a comprehensive approach of their mobility patterns.

The questionnaire was elaborated thank to a collaborative work involving experts of mobility surveys and representatives of associations for disabled people who contributed to apprehend the wide range of disabilities, the heterogeneity of this population and their expectations.

The paper will detail key learnings from the outgoing of the survey which is the first one of this type in France.
It will also present its main results:
• How many people are concerned by mobility impairment in Ile-de-France?
• What are the differences regarding mobility between general population and disabled persons? This point will be appreciated both by the comparison of the results of the survey and by the comparison with the last general household mobility survey conducted in 2010 in the region.
• How do people judge the current level of accessibility and do they have perceived some (positive) evolution?

Besides giving a picture of the current situation, the survey will also be the starting point for measuring the impact of the regional master plan for accessibility.
