A traffic error correcting circuit for use with a dispatching system circuit operable to control instructing means for directing traffic to a plurality of receiving stations in response to electrical traffic request signals and request cancel signals from the stations. The error correcting circuit automatically compensates for traffic error or failure to obey the instructing means by automatically providing additional traffic request signals as required without requiring attendants at the receiving stations to constantly monitor the directed traffic.
