Mitu-yoho
Mr. HATANO Yuta and Mr. SANAMI Tetsuro

A web service that simulates congestion due to detours when routes are suspended

When a railway route is closed, detour routes that avoid the closed route and the closed route itself immediately after restoration will be more crowded than usual. On the other hand, the trains that the cancelled trains were scheduled to connect to are expected to have fewer passengers than usual. Mitu-yoho defines a “stay” as staying of someone within a one-kilometer radius for more than 15 minutes, and calculated the demand for travel from one place of “stay” to another based on the past floating population data. Of these travel demands, those that can be covered by public transportation within the maximum calculated time to travel are defined as public transportation demand.

The total demand for public transportation on the same day of the week in the same month as the day for which congestion is to be estimated is used as the demand for the day for which congestion is to be estimated. The route used for each demand is calculated using a route search engine, and the train to use for travel is guessed.

In addition, Mitu-yoho considers trains that are delayed for more than 10 minutes as trains to be avoided, and their operation data are excluded from the route search engine. This app simulates and visualizes how congestion develops when public transportation demand on the estimated congestion day is met by trains other than the avoided trains in contrast to normal times.

Public Transportation Irregular Event Notifier (PIEN🥺) for Tokyo
Mr. Akihiko Kusanagi

Twitter Bot service that delivers real-time information on railway delays and operation suspensions in the suburbs of Tokyo

Public Transportation Irregular Event Notifier (PIEN🥺) for Tokyo is a Twitter Bot service that lets a figure, "Pienta-kun," deliver real-time information on railway delays and suspensions in the suburbs of Tokyo. To use it, just follow the Twitter account @pien_tokyo. Daily train operation status information provided in the Open Data Challenge for Public Transportation in Tokyo is delivered with humorous illustrations and a friendly tone.

This service operates as a Python script on Google App Engine. It obtains train operation status information every minute, and checks the differences in the text for each route. If there is an update to the information, the service converts the text into the colloquialism of "Pienta-kun," selects an illustration that matches the reason for the delay from 43 illustrations, and posts it through the Twitter API.

The results on my performance since the account was opened in December 2020 are as follows;

The PIEN 🥺 Tokyo Train Information Stamp is now available on the LINE stamp shop.
