BMW introduces new traffic information system

BMW Connected Drive as part of its program to introduce a new traffic information system. For the navigation systems of the brand developed Real-Time Traffic Information (RTTI) provide for the routing and forwarding recommendations of the traffic situation in real time. Additionally, on motorways and trunk roads captured this new system also roads and many inner-city connections.

To analyze the traffic conditions are considered significantly more data and updated frequently. This gives the driver of a BMW in the future delivered in addition to the traffic jam warning on its current route and precise information on traffic conditions on a potential detour. Unexpectedly, a delay occurs on the alternate route are a thing of the past.


Instead, the navigation system is also under difficult conditions the actual fastest route to the controlled target. Stand next to date traffic information to the police only a limited number of sensors on freeways and expressways function available in the future moving or stopped vehicles as indicators of self-moving or stalled traffic.

are connected by-truck fleets of taxis and freight forwarders to their navigation systems with a control center, provide the additional vehicles carried in mobile data, which indicate congestion or slow-moving traffic. Based on the dynamic network connections of mobile devices, anonymous movement profiles are determined, which are transmitted to the entire road network.

From the number and rate of change of location within the cellular network can draw conclusions about the traffic situation. The transmission of data in real time over the GSM cellular network. An active Smartphone app is not required. In addition, local traffic management systems are included in the data collection.

The driver also receives information about many cities in possible delays on highways and city connections. In four shades - from green for free travel through yellow and orange for slow-moving traffic to stop and go up to red for stop - the particular traffic situation is displayed on the display.

The detected road network is divided into sections each 500 meters long, the updating of information is done at intervals of three minutes. In addition, the user can recognize on the basis of changes in the map, if the traffic situation has worsened or the dam is already in disarray. Thanks to the detailed data on an extensive and dense road network provides RTTI also significantly more reliable diversion recommendations.

Is reported for example for a section of a highway traffic jam, the navigation system with route guidance activated immediately determine the resulting delay. But not only that: Since the first time, the traffic situation on the roads off the highway is detected, the system provides informative diversion recommendations.

The risk gets on the detour route to once in a traffic jam and losing additional time is reduced considerably. Call forwarding recommendations to include precise information on the distance and time difference of the alternative route compared to the currently planned route. With this knowledge, the driver can also take the traffic jam on the main route into account, if the eligible alternative route allows no or only a small time savings.

Or he may opt for a long detour in order to be more relaxed and it may still appeal a charming stopover. Prerequisite for the use of RTTI is equipping the vehicle with the Professional navigation system, including mobile phone preparation with Bluetooth interface. The new generation of traffic information is offered as a fee-based extension in the context of a BMW Connected Drive-contract.
