Weekly overview
Stability was the predominant result. Of 438 routes compared, 144 (32.9%) had more observed vehicles, 267 (61.0%) remained stable, and 27 (6.2%) declined.
route SN319 averaged 2.76 more vehicles per day, moving from 1.67 to 4.43 (+165.7%). route 61 averaged 10.91 fewer vehicles per day, moving from 53.2 to 42.29 (-20.5%). At least one highlight starts below two observed vehicles per day, so the absolute difference should be read alongside the percentage.
Among the compared groups, Transcarioca had the highest average change (+11.8%), while MOBI-Rio had the lowest (+3.5%).
In the 30-day context, 17 routes entered the critical range. Leading cases include route 898 (Sepetiba - Campo Grande) because of reliability score of 34/100 with low confidence; route 11 (Santa Cruz - Terminal Alvorada) because of reliability score of 34/100 with low confidence; route 498 because of reliability score of 48/100 with low confidence.
The historical window covered 30 of 30 days. Of 490 candidate routes, 438 entered the comparison and 52 were excluded for insufficient data. The figures represent observed vehicles and do not measure passengers, occupancy, revenue, or regulatory punctuality.
