Use of data

Data issued from
the usage of public transportation can be anonymized and used to produce maps
showing when and where people are traveling, giving both a far more accurate
overall picture, as well as allowing more granular analysis at the level of individual
journeys, than was possible before. As a large proportion of Paris journeys
involve more than one method of transport, this level of analysis was not
possible in the days when tickets were purchased from different services, in
cash, for each individual leg of the journey.

For example, the metro, passengers are used to “checking out
and checking in” – tickets are validated (by automatic barriers) at the start
and end of a journey. However, on buses, passengers simply check in.

Traditionally tickets were purchased from the bus driver or inspector for a set
fee per journey. There is no mechanism for recording where a passenger leaves
the bus and ends their journey – and implementing one would have been
impossible without creating an inconvenience to the customer. So, can we use
Big Data to infer where someone exited? We know where the bus is, because we
have location data and we have data for entry, what we do next is look at where
the next tap is. If we see the next tap follows shortly after and is at the
entry to a tube station, we know we are dealing with one long journey using bus
and metro. This permit to understand how crowded a particular bus or range of
buses are at a certain time, and to plan interchanges, to minimize walk times. We
can also use big data to study origin-destination pairs at different levels and
thus optimize the transfer times if big chunk of population faces the same “inefficiency”

Collaboration between the citizen and the city

The citizens must be involved in the city mapping we must therefore promote the acquisition of
sensors by citizens and the development of tools for feedback and analysis of
information. *****give information to the user ********

collaborative
mapping can be used as a tool for urban development and resilience. Finally,
this mapping will be conceived as a true public service of the data ensuring
the reliability, the free and the guarantee of a benevolent use of the data
produced on the territory.

Free public transportation

Public transportation of metropolitan cities is a crucial
part of the solution to the nation’s economic, energy, and environmental
challenges – helping to bring a better quality of life. In increasing numbers,
people are using public transportation and local communities are expanding
public transit services. Free public transportation will encourage people using
it rather than choosing the option of private vehicle which will result in
overall low pollution emission.

Free public transportation can also create other positive
externalities such as a more efficient labor markets since it is easier for
poor people to get to jobs. This is a benefit to employers for it makes it
easier to hire people and it is a benefit to the people without cars who now
find it easier to get jobs. But it is also a benefit to the society at large
because it contributes to a long-term reduction in poverty.
