Traffic Monitoring Systems
Traffic monitoring system TMCS
With the TMCS inductive loop detector/classifier for 8 double loops (extendable to 24), Traffic Data Systems presents a product which is also supplied to OEM customers (Original Equipment Manufacturers). Thanks to high integration density and excellent performance features , it enables all providers to put forward a system with outstanding results and first-class references.
Compared with slow multiplexer methods, high scan rate of 1000 measurements/s per loop guarantees very accurate speed measurement and uninterrupted recording of signatures, which leads to more accurate classification results in the signal processing unit. Superimposed loop frequencies prevent interference even with long feed cables. All data, such as vehicle class, speed, vehicle length, net time interval and occupancy, can be interrogated sequentially and displayed on the graphical display simply by pressing a button.
The TMCS is available as a stand-alone FG1-EAK including display, Ethernet, USB and RS485 interfaces. The interval modem and the holder for the SD card are not required. The function group FG 1 outputs interval-controlled short-term and long-term traffic flow data, which are gathered and evaluated by BASt-certified inductive loop detectors/classifiers. The measuring intervals can be parameterised from a central unit or locally.
The system can be expanded to form a compact online traffic monitoring system using an optional GSM/GPRS/UMTS modem and an SD card. A stable system clock with a resolution of 10 ms, which is synchronised via the Internet, adds a time stamp with date and time to the data. An Ethernet interface is provided for project engineering.
As standard, TLS-compliant short-term and long-term FG1 data are determined and made available for interrogation by a central unit. Long-term data can also be read out locally and transferred to a notebook or PC using an SD card or memory stick. Long-term data can be kept in the system for several months.
If required, the TMCS can also register individual vehicle data over a period of weeks and months. The data input block structure in Type 63 according to TLS or extensions thereof is used for this purpose. SD cards with storage capacities from 256 MB to 32 GB are used as data media.
A root server on the Internet is provided for the online connection of remote monitoring stations where there are no roadside telecommunications cables or telephone landlines. Both of the TMCS designs described above are available as a top-hat-rail-mounted module or as an 8-unit wide 19-inch rack-mounted assembly. A motherboard is not required.
8-lane double loop detector/classifier
The same learning set is used in the TMCS as in the VDK 900 detector/classifier with 8+ 1 vehicle types certified by the BASt. Special learning sets are provided for customers in other countries (Light Goods Vehicle with Trailer and Gigaliner).

| Gigaliner |
* NCV: Non-classified vehicles
TLS 2002 suitability test
The TMCS is to be tested by the BASt in the second half of 2011. Because of the common learning set with the already approved VDK 900 detector/classifier, the TMCS will also achieve accuracy class A1 with a cable length of 300 m with 2 pairs of cores per loop in the TLS suitability test.
