Personal Freeway Assistant.
An Information-as-a-Service data feed bringing dynamic roadway sign information directly to the driver.
Our Personal Freeway Assistant brings freeway information to the driver in their dashboard or via our mobile app. Dynamic lane control and speed limits ease the flow of traffic, but adaptive cruise control relies on cameras for sign status. With PFA, we provide 99% sign information accuracy updated automatically.
Active Traffic Management (ATM) for freeways, including dynamic lane control and dynamic speed limits, has become the tool of choice for stabilizing freeway traffic flow over the last 30 years. The implementation of speed funnels ahead of hazardous locations (i.e., incidents, road works, etc.) resulted in significant safety benefits. To date, ATM systems have been installed on approximately 20% of European freeways. |
How Does It Work?Working with SuppliersData suppliers for this product are the State DOTs and their traffic management centers where operators or automated algorithms can define sign settings and all states are archived for potential use in court. The TTS cloud captures the live status data directly from the traffic management centers and transfers it to our clients’ backends together with the geo-referenced location of their corresponding gantry.
Working with PartnersTTS works closely with industry leaders to ensure stable and reliable data access to the respective regional traffic management centers. One of the technology leaders in this space is Heusch/Boesefeldt GmbH, who serves as our primary partner for Germany and Austria.
CommunicationsTTS receives current states of each dynamic lane control sign according to the update frequency of the respective ATM system. Typically, this means that states are regularly updated every 15 seconds for tunnel management, 60 seconds for dynamic lane control, and 15 minutes for dynamic route guidance. Furthermore, TTS instantaneously receives and provides push notification for event-based control switches (e.g. lane closure in response to an accident).
