Angry engineer measures 'subway quality' by compiling disturbance data


Exasperated by repeated delays, Romeo, 22, collects and analyzes RATP messages on Twitter. According to his barometer, the lign

On Twitter, he manages the @MétroQualité account.

But in real life, his name is Romeo.

This young 22-year-old engineer lives in the 11th arrondissement of Paris and is used to taking line 8 every day.

Like millions of metro users at rush hour, he often has to take his troubles patiently.

“On line 8, there have always been problems.

Except that since the start of the school year, it has exceeded the limits!

“, he breathes.

Long waiting times, overcrowded trains… the metro has experienced a sharp deterioration in service since last September.

“The worst thing is that there is no transparency, judge Roméo.

The RATP's messages speak of operational difficulties, which are repeated day by day… It's incomprehensible”.

"Turn my anger into something useful"

“Tired”, this engineer specializing in data processing then decided to set up a system of “bots”, small automated software that compiled traffic info messages broadcast in real time on the RATP site.

“Initially, I wondered how to turn my anger into something useful.

I said to myself that it would be good to have an overview of the disturbances of the metro and the RER, for each line”.

To start the year off right, here is a report on the quality of the Parisian "Metro" network since November 30, 2022.

More than 5 hours of disrupted traffic every day on line 12

This information is formatted to calculate the average disturbance time on each line.

Result: according to the data collected between November 30 and January 4, lines 12, 8 and 6 are those which experienced the longest incidents.

On average, Route 12 experienced more than 5 hours of disrupted traffic on average each day.

Lines 7, 9 and 13 are also on the list of problem lines.

Roméo also classifies the descriptions of incidents put forward by the RATP.

“Operating difficulties” (463 incidents), security measures (221), forgotten baggage (136), operating incidents (89), passenger discomfort (80) or people on the tracks ( 76) are the main sources of malfunction.

For its part, the RATP advances multiple factors to explain the deterioration of the last few months: lack of drivers, lines under construction, forgotten luggage, etc.

The management ensures that hundreds of recruitments are in progress and that an improvement is in sight "at the end of the first quarter".

An extraordinary council of Île-de-France Mobilités is precisely scheduled for Friday with the leaders of the RATP and Transilien to specify the timetable for a return to normal traffic in 2023.
