Ottawa, Ontario

@OCTranspoAlerts provides unofficial notices of transit service disruptions by tweeting Ottawa transit service disruption alerts. Although not affiliated with OC Transpo, this feed automatically tweets run cancellation notices based on OCTranspo.com information and route delay alerts based on Open Data via OCBus.ca.

Open Data is also used to estimate the percentage of delayed buses at any given time, a typical bus delay, and a range of the delays for transit users.

Since 2010, @OCTranspoAlerts has been providing updates to thousands of followers including various media outlets, city councillors, and of course, OC Transpo passengers.

Sometimes mistaken for the official account, this feed has influenced the frequency of OC Transpo's online service updates and the language used in the transit agency's notices. Its tweets are seen 6300 times per day and 190 000 times per month on average.

@OCTranspoAlerts notices can sometimes be heard on CBC Radio and 1310News traffic reports. The feed has been featured and mentioned in:
