Disruptions in the Paris metro were analyzed by the Twitter account

The number of incidents per day, the average duration of interruptions… A Parisian engineer decided to collect the data published by the RATP to visualize the “quality of Paris public transport” line by line.

A Twitter account dealing with crowded trains at rush hour “@MetroQuality” Analyzes traffic data statistics of RATP infographic Published on Wednesday 4th January, we look at the number of daily incidents across the entire metro network since 30th November 2022.

Several figures are put forward, including an average of more than 37 hours of downtime per day. Most “problem“: from 17: 00 to 18: 00.

According to the Twitter account, which states that the report is independent of RATP, the most incidents were recorded in lines 12, 8, 4, 9, 13 and 6. As for the total duration “in anxiety“, line 12 also comes to the pole position. And so new postAs of Monday, Jan. 9, Line 12 has been out of service for about 25 hours over the past seven days, an average of about 4 hours per day.

The account was created by Romeo, a “data engineer”. proliferation of disorders on the RATP network in recent months. “I was mainly a user of metro number 8. There have always been problems, it drives you crazy. And every morning I saw the famous “operational events” on RATP’s Twitter account. So I wanted to imagine the riots over time. Now I skip line 8, I take line 3 as well, even if it’s not great“, says the young man.

pointing to Romeo”lack of transparency“and”reading problem“, thus creating a “bot”: an automatic program that checks every five minutes traffic information site To collect information about RATP, metro, RER, tram and some Transilien lines. “Specifically, the bot checks if a new incident has been reported and tracks it in the database. When the event is no longer announced, the bot records the time of the concern’s end“, he detailed.

His Twitter account also analyzes the origin of the events. According to a January 4 report, “operational difficulties” thereby causing 463 hours of unrest. “security measures” (221 hours), “forgotten luggage” (236 hours), “operational events“(89 hours), “traveler’s discomfort“(80 hours) and “people on rails(76 hours).

When contacted, RATP noted that “operational event“is”general term used in passenger information at the start of the incident (…) unless we have more precise information. Therefore, the term can refer to any event: an emergency brake, a serious passenger accident, a suspicious package, etc.“The group calls elsewhere”several tens of thousands of incidents occur in the subway every yearwithout giving exact figures.

The number of events is not a complete indicator for the analysis of operational quality

As for “Difficulties encountered in the network since September“happy end of the year”especially difficult“, RATP mentions several factors: “lack of drivers (absenteeism and understaffing)“, “absence of trains“on certain lines”Care groups follow a social movement“, “the effect of his works“…According to the group,”the number of events is not a complete indicator for the analysis of the quality of the operation, some events have no effect on the operation“.

RATP, which says it is accelerating its recruitment and training plans, also points out that “operations should improve significantly in the coming months, by the end of Q1 2023“.

For his part, Romeo hopes to see her curves”reverse“and after the rapid improvement of the traffic situation”A truly awful end to 2022“I want to be an engineer in the future.”Fully automate your Twitter account“, “maybe create a website to visualize all the data with filters“, also follow the bus network.
