Control ModelPriorities
Priorities• Overlapping of priorities of individual VMS due to adjacent funnels. VMS with
highest priority will be selected.• A certain priority can be given to each VMS dependent on the automatic
programme and on the VMS-gantry.
Default Priorities• If no priorities are assigned to the funnel the (system specific) default priorities
will be used.• Use of default priorities in case of special programmes.
Individual Priorities• Individual priorities will overwrite the default priorities in defined cases.

Control ModelSupply of up- and downstream VMS
Up- and Downstream VMS
Only downstream VMS are supplied (details about type and location).
Each VMS has no or only one downstream VMS.
The downstream VMS are used for the stretch-related comparison.

Control ModelIterative Improvement of the Switching Requirement
Cross-section tuning for VMS Speeds shown on one VMS-gantry must
be increasing from the right to the left lane. Different restrictions on overtaking with
different priority exist which can be shown via VMS Type B and C.
Priority VMS-Type B VMS-Type C
1 general restriction on overtaking „Dark“
2 restriction on overtaking for lorries „Dark“
3 restriction on overtaking for lorries "4 t"

Basic principles of the Control System
switching request only in case of (danger of) congestion on the regular route
detour only in case of free alternative routes, i.e.– no congestion and no danger of congestion, also taking
into consideration the amount of diverted traffic

Congestion is detected, if
• the prognosis velocity vp falls below a certain threshold value
or if
• the density of the prognosis kp is higher than the threshold of k0 * f (congestion)
Danger of Congestion exists, if
• the prognosis density kp is between k0 * f(danger of congestion) and k0 * f(congestion)

Switching requirement only in case of congestion (or danger of congestion) on the normal route (at least one detection point with (danger of) congestion)
Rerouting only in case of free alternative route, that means– no congestion or no danger of congestion, considering also the
diverted traffic

Fusion of Local and Mobile Traffic Data in a Fuzzy-Logik-Approach combining the Benefits of both kind of traffic data
Basis of FCD: GAT-StandardProblems of FCD:
– FCD only represends a spot check of the traffic Stream– it is not ensured, that there is a FCD Pentration in the analysis time frame statistical Analysis of the Repesentative of FCD is needed
Benefits FCD:– Exact Travel Time Estimation– Enlarged Traffic Condition Analysis (exspecially: Exact Location of Traffic Congestion; jam velocity etc.)
Outlook: Integration of FCD

Fusion of Local and Mobile Traffic Data in a Fuzzy-Logik-Approach combining the Benefits of both kind of traffic data
Problems of local Data:– represents only the traffic conditions at the data collection point Uncertainties in the transmission of local data to the related
section
Benefits local Data:– Traffic condition Analysis is ensured for all analysis time frames by the Integration of local Data
– Data is collected for the whole traffic stream, and not only just for a spot check (FCD)
Outlook: Integration of FCD
