Digital Traffic Surveillance
with
Traffic-Observer
Type LMS-06
With the system series Traffic-Observer, ces ag provides
public authorities with modular solutions for automatic
traffic control.
The main item is a laser measuring system with a digital
recording unit.
It detects speeding, going through red lights, as well as
driving against the traffic on motorways. Violations are
saved on a digital photo, including all relevant measuring
data. By the means of a CF-card or direct network
con-nection, the traffic violations are passed on to the data
administration concerned. A special software enables
authorities to issue invoices for fines efficiently.
In contrast to conventional speed or red light surveillance
systems, which cannot work continuously due to the
ti-me-consuming changing of films on site, Traffic-Observer
systems are ready for use around the clock.
Combined red light and speed measuring
system Traffic-Observer LMS-06 without
costly structural works
The LMS (laser measuring system) detects motor cycles, pri-vate cars as well as trucks, and records this information toget-her with the geometrical characteristics. The objects are follo-wed as long as they are within the field of vision of the system. The speed and the distance covered are recorded and made retrievable by the system. This process has been extended so that vehicles, even if not visible for a short time (measuring shadow) can be traced speculatively.
Traffic-Observer LMS features state-of-the-art mechatronics and outstandingly high reliability. At the same time, the LMS sensor is unequalled as far as minimal installation costs and
maintenance are concerned. Compa-red with conventional speed measu-ring instruments (inductive loops, double radar), Traffic-Observer LMS produces qualitatively excellent mea-sured results.
All electronic components meet the highest industrial standards (Com-pact-PCI System).
Its mechanical components, however, are not neglected either. All the com-ponents are fitted into a robust cabin. In order for it to withstand any type of environmental condition, the doors, lateral walls and roof have double walls and are provided with small ho-les for airing.
Besides high-resolution digital camera systems, the Traffic-Observer sales program also includes flashlights (Speed Light) in conventional techno-logy, as well as IR-Flashes (LED tech-nology).
The digital photos are provided with an unambiguous signature in order to avoid any possible misunder-standings. This signature is examined automatically when processing the pictures, so that illegal changes in the picture are indicated immediately. In order to
ensure an unambiguous assignment of vehicles on streets with several lanes, the direction of travel and the lane of the vehicle in question are also documen-ted in the picture inserts, besides the usual informati-on.
How it works (LIDAR)
The Traffic-Observer laser scanner operates on the principle of pulsation runtime measuring: A pulsed la-ser beam is emitted. If it hits an object, it is reflected and registered in the receiver of the scanner. The time between the emission and the reception of the impul-se is directly proportional to the distance between scanner and the object (time of flight).
By means of an internal cheval glass, the laser beam is diverted and the environment is scanned in a fan-shaped way (laser radar).
From the series of the received impulses, the contour of the object is computed. The measuring data are ready for further assessment in real time at the
inter-face. In the scanner, an automatic fog correction is active. Rain drops or snow flakes are blanked via a pixel-oriented assessment.
The computed and measured data are made available in real time and are shown directly in the picture.

LMS-06 Features
•Laser based, therefore no structu-ral works on the roads are neces-sary.
•With regard to its implementation, what is needed is only a 230V supply and the laying of an anchor plate.
•Only one measuring cabin is ne-cessary for both front and rear views of vehicles.
•On motorways, selective measure-ment of different vehicle categories is also possible of arriving traffic (frontal views of trucks).
•Modular build-up of all compo-nents, electronic as well as me-chanical
•As a removable data carrier, a CF Card with 4-8GB capacity is provi-ded (this means that with 4 pictures in best resolution per traffic violati-on, 500 – 1000 cases can be
sto-red on one CF card.
•No waiting time for download, sin-ce the pictures and measured data are stored on the CF card parallel to the internal HD.
•The picture data are signed and saved in JPG format.
•Per traffic violation, either two front and two rear view pictures can be saved and assessed, or alternati-vely only one front and one rear view picture.
•The saved data can – if data lines are available – be transferred di-rectly to data processing facilities via the network.
•The incorporated digital cameras with RGB-CCD sensor of the size 23.7x15.6mm and with an effective resolution of 6.1 mio pixel guaran-tee the best possible picture quali-ty.
•Thanks to the electronic documen-tation of focal length, it is possible for the first time to implement a zoom lens with f 18-70mm.
•Time synchronisation is effected via GPS satellite receiver.
•Allowed range of speed: 10km/h-300km/h

The LMS-05 equipment now also for mobile use
The mobile LMS-05 measuring equipment consists of the same components as the permanent LMS-06 installation. The system is already in use successfully in Swit-zerland. The standard equipment contains flashlights, digital came-ras, INTEL processing units as well as a data transfer system.
