Project Traffic Management   (Aktiv-VM)

 

The interaction of intelligent vehicle systems and intelligent infrastructure units is the objective of the Aktiv-VM project. This novel kind of team work will create new modes of co-operation between automotive industry, road network operators and the ICT sector. But “Cooperation in traffic” also means a stronger interaction of technical processes which will be enabled by use of new technologies, software and new communication media.

 

The 6 Aktiv-VM applications combine traffic and information centres, road-side infrastructure and intelligent vehicles in a novel manner:

 

                                    - Network Optimizer

                                    - Virtual Traffic Guidance System

                                    - Cooperative Traffic Signal

                                    - Adaptive Navigation

                                    - Situation-Responsive Driving

                                    - Information Platform

 

The two cross-sectional subprojects are:

 

                                    - "Assessment" and "Cooperation and Innovation Forums"

 

 

Projekt Partners and Costs

 

 

 

 

The “Network Optimizer” is working on the current traffic situation calculated in a centre, which will be interpreted and transferred into a package of information and measures. Infrastructure equipment like variable message signs will be supplied directly. In close cooperation with the application “Information platform”, today’s unidirectional information flow will be extended to both directions between “public” and “private” partners.

 

 

 

 

 

The “Virtual Traffic Guidance System” will play a key role within the road side infrastructure systems. In addition to display traffic information on a message-sign, it will be communicated directly into the vehicles. Today known information as well as new information can be displayed in the vehicle or used by intelligent onboard driver support systems. Virtual means that information can be distributed at important locations (e.g. construction sites) completely without infrastructure equipment.

 

 

The “Cooperative Traffic Signal” will care for the control of traffic flow at traffic junctions. Existing traffic light systems will be integrated into the new communication-concepts of Aktiv-VM applications. This is of special importance for the improvement of  detour traffic control adapted to traffic situation. The advantage will be reduction of noise, pollutants and queue time on light-signal systems.

 

 

 

 

 

 “Adaptive Navigation” is developing cooperative vehicle-infrastructure technologies for dynamic navigation and for driver information. In addition to Broadcast and UMTS, a direct bidirectional communication link to infrastructure based applications will be established. Travel-times, strategic driving re-commendations and infrastructure information can be integrated and offered to the user in a single system. Situational information (warnings, speed limits) will be displayed.

 

 

 

Technologies for optimization of traffic flow by anticipatory and cooperative driving in special situations are the objective of the “Situation-Responsive Driving” application.  The performance of the road network in critical situations like in road construction areas will be improved by local traffic situations detected by the vehicle, the information exchange between vehicles as well as between vehicle and infrastructure. The information is used by the vehicle systems.

 

 

 

 

 

The „Information Platform“ will be the central node for strategy and traffic information. It is handling the preparation of data and information from different sources and the provision of application-specific information on different content levels. The platform is also supporting the geocoding and the decentralised support of specialised map attributes.

 

 

 

 

 

Precise statements concerning the effect potential of those applications will be supplied by a subproject called “Assessment”. This evaluation will be based on extensive field-tests to be performed in the test field Hessen. The Aktiv-VM results gained will be discussed in showcases with experts in the so called “Cooperation and Innovation Forums”.
