A traffic management system uses a network of traffic detecting apparatus distributed through the traffic network, such as at each traffic light and detects vehicle IDs of passing vehicles, such as by detecting Bluetooth addresses from Bluetooth transmissions, and sends capture messages back to a traffic network monitoring centre. The traffic network monitoring centre estimates travel times, excess delays and congestion, and sends traffic status messages to the traffic detecting apparatus. These broadcast the message, for example in a modified iBeacon frame, which is detected by mobile devices in passing vehicles, and an app running on the mobile device parses the traffic status message and generates traffic alerts and information messages to users, for example by outputting an audio representation of the message on the mobile device or vehicle audio system.
