Ok. But how much compared to the other cities?

And in the world?

CityChrone: the context

The first definition of accessiblity in urban context is done more than 50 years ago

But no attemp to compute it at large scale.

This work must be considered, first of all, as an empirical work. It defines procedures to measure quantities and then we measured them.

Prerequisites

Data, algorithms and data visualization.

Quantity Definition

Easy to understand, easy to compute and meaningful quantities to measure public transport efficiency.

Collective creativity

Exploring the huge and complex space of new configurations of the public transport in cities

** Data, visualizations, algorithms **

CityChrone

Science for City

Boundaries and Tessellation.

It is possible to compute **isochrones**

First step towards an accessibility measure:

The larger isochrones are, the faster you move.

Velocity Score

Average velocity taking a random direction

Paris
Rome

interactive maps and more cities:

Sociality Score

Number of people is possible to reach in a typical day trip starting from a point.

Rome

interactive maps and more cities:

City Rankings

City Velocity

Velocity Score per person

City Sociality

Sociality Score per person

Cohesion

City Sociality divided by total population

Values distribution

Area distributions - Population distributions

Inequality distribution of
**accessibilities**

Exponential decay from the center of the city.

Exponential decay of the Velocity Score with the time distance from the center.

Exponential decay from the center of the city.

Exponential decay of the Sociality Score with the time distance from the center.

Are these inequalities unavoidable?

In which way?

I don't known.

The future of public transports in cities

Bad ending for my current research, but happing ending for public transport in the cities?
