Traffic Alert Program


Traffic Alert Network

This FREE email or text message service provides you with timely information about construction, accidents, and incidents that are expected to impact traffic and transit. Whether an accident has shut down Route 1 South or a train breakdown is causing delays, this service will keep you informed.

Construction Alerts, Shuttle alerts, and similar notices may be sent at any time during normal business hours, Monday - Friday.

Traffic and Transit Alerts are generally sent between 3:30 PM and 4:10 PM in preparation for the evening commute, Monday - Friday.

All alerts usually contain the following information:

Where? - The route that is affected, and the town in which the incident/construction is taking place. 

When? - The date and time of the incident, and often the likely duration of its effects.

What? - A description of the construction, incident, or transit service change.

GMTMA provides traffic alerts for Mercer and Ocean counties. Mercer Alerts and Ocean Alerts are available by email and text message to everyone. We also send out some information to interested subscribers regarding construction and incidents in Bucks County, Pennsylvania.
