collection environment

The city of Rio de Janeiro is one of the metropolises of Brazil, having in 2010 over 6 million residents. The city has about 1,200 km² of area and over 11,000 km of streets, where 2,576,947 vehicles (17,723 buses) circulated in 2014.

According to operational data from the buses controllers, obtained at the website of the federation of transport companies in the Rio de Janeiro state, in October 2014 there were 725 active bus lines, with a fleet of 9,028 vehicles which made 1,832,461 travels that month, covering over 72 million kilometers and carrying over 117 million passengers.

network configuration

None information of how the data is gathered is provided by the data maintainer. Nevertheless, we discovered that each bus have a GPS receiver and the data is sent to a central facility in near real time by a 3G cellular network.

data collection methodology

Real-time position data reported by the buses, updated every minute, plus other transport data, like stops location and bus routes, are made available by the city of Rio de Janeiro through the open data portal of the city http://data.rio/en/dataset?groups=transporte-e-mobilidade. We collected these data because it represents the actual shuttle of the public transport vehicles, in addition to contribute to analyze and eventually share an expressive location data collection of a large number of vehicles. The collected data is from October, 2014, in a month period.

sanitization

These are the raw data, only compiled all measurements performed per day.

disruptions to data collection

From 2014-10-24 to 2014-10-28 there were some system failures in the acquisition website. Those days have fewer or none data.

error

As this dataset are raw data collected from the data.rio website, there are error in the database, mostly related to GPS location errors, as measured by the buses. We also found some errors related to the message from the data.rio. These errors changed some numerical information of the message, like buses ID or even buses locations. Those errors are infrequent.

note

The new version (2018-03-19) is actually a correction to the original release that had a bad data file. Ignore that release moving forward.
