Incidents

Rail, bus, and elevator disruptions/outages.

XML - Bus Incidents

Description

Returns a set of reported bus incidents/delays for a given Route. Omit the Route to return all reported items.

Note that the Route parameter accepts only base route names and no variations, i.e.: use 10A instead of 10Av1 and 10Av2.

Bus incidents/delays are refreshed once every 20 to 30 seconds approximately.
