As of 2015, there is not a Garden State Parkway map for smartphones. However, the New Jersey Turnpike Authority offers the SafeTripNJ app for drivers using the Garden State Parkway and other major roads in the state. The driver activates the app on his smartphone and listens for advisories.
SafeTripNJ uses global positioning satellites to track the driver's location and traveling direction. As the driver nears a traffic issue, the app announces the travel advisory. Also, the app allows the driver to set a time range for the program to rebroadcast any travel advisories within his current location. The driver selects how often to hear traffic advisories with this app.
