In our own training centre at the company headquarters in Tönning, or on-site at your location, we share valuable knowledge about mobile telematics. This includes practical instruction in the details and function, in addition to compliance with regulations. Email us at vertrieb(at)nissen-germany.com to obtain a quote on a customised training session.
A team of specially trained experts is available to answer all technical questions relating to hardware in mobile telematics applications and control and display sections. From operation to maintenance and repair at your site. We look forward to your call
The components of a mobile traffic jam detection in compliance with M-TI 2015 include:
  • LED variable message signs complying with M-TI. Parameters such as the technical version, size of the message signs, photometric requirements, the display of texts, etc. are defined there.
  • Traffic jam sensors with automatic generation of the levels of service.
  • Central unit (TrafficManager) complying with regulations for controlling and monitoring the devices. Requirements of the M-TI are for instance the status display of the devices and location determination.
  • Monitoring of the devices by means of an OC complying with regulations, with a guaranteed annual availability of the devices of 99%.
The LED variable message signs and traffic jam sensors that are already available must be compatible with the TrafficManager. An ID indicating this compatibility of Nissen products can be found in the product catalogues. Furthermore, the devices already available must be equipped with a modem and the corresponding SIM card in order to ensure communication via the mobile network.
The response time between the documentation of an error and the start of error correction is 45 minutes. The error correction process is documented with regard to its time and scope.
All traffic signs stored on the storage medium of the variable message sign are retrieved and switched by the TrafficManager. Additionally, an integrated design editor is used to freely create simple images and texts. For more complex designs of images and texts, we recommend using the NiCo 2 Designer software which is included in the scope of supply.
Communication between the devices and the server structure is carried out via GSM (Global System for Mobile Communication). This is the mobile radio standard of the second and third generation. The browser with the online application in return communicates with the server via HTML.
The AES encryption (Advanced Encryption Standard) is utilised. Indicated by the URL (https). The AES encryption is considered as the common form of encryption and is for example also used by banks for the purpose of online banking.
The application works on all common and current terminal devices and web browsers. However, in order to ensure optimum handling of the application, Firefox and the Chrome browser are recommended.
The user level provides three ways of regulating user access:
  • Admin: can create/switch devices, create projects/subprojects, create scenes/site plans
  • Operator: can switch devices, create projects/subprojects, create scenes/site plans
  • Viewer: can only view projects/subprojects, only view scenes/site plans
In order to represent the devices via Google Maps, a Google account with a stored API key is required. When the Google account has been linked with the TrafficManager, Google provides a free quota of calls per year to the user. This quota is usually sufficient for the user.
Two panels on the left-hand and right-hand lane
DS1.1 is display section 1 on the left
DS1.2 is display section 1 on the right

Circuits in the case of which individual signs or whole scenes are switched automatically in a sensor- or time-dependent fashion.

Mobile warning trailer (MWT)Warning trailer serving to secure work sites and scenes of accidents. Also known as warning sign trailer.

A barrier board mounted on a trailer and used to secure roadworks and accident sites. Also known as a warning arrow trailer or traffic safety trailer.
Term for a remotely controllable or monitorable unit, e.g. LED variable message sign (VMS), MWT, warning system, CB warning system, traffic box (measuring unit) etc.
The site plan is a graphical view in which the control and display sections can be represented in compliance with traffic regulations in the road section
In contrast to the static message signs, LED variable message signs allow for the dynamic display of almost any symbols and texts. They are often mounted to trailers (mobile LED warning signs) with warning lights that have a facility for lifting and lowering.

Calculated traffic jams of a CS

1 = free-flowing traffic
2 = traffic jam warning (slow-moving traffic)
3 = traffic jam

Mobile traffic light.
Organisational unit that represents a company. Clients can contain multiple projects and sub-projects.
Unit for transferring data and control commands to and from the device via the mobile network.
Traffic box with 1 to 4 sensors
Combination of DS and CS, central unit and OC for the automated warning and speed regulation at work sites in road traffic.
M-TI-compliant data centre for setting up, controlling and monitoring mobile traffic management systems (mCWS, VMS). Redundant mirrored servers and online connections as well as permanent staffing (365 days a year, 24/7) are necessary.
Circuits in the case of which transmission is not carried out by the control signal but the display graphics and, if necessary, also texts are created by the user and are directly transmitted to the variable message sign.
Program for the creation of images and image sequences for the variable message signs. Is in particular used for Over-The-Air circuits.
A program in the LED variable message sign is an image sequence that is typically stored in the local library on the storage medium of a device.
Measuring unit that records data and transmits them via the traffic box. Traffic boxControl section: device for measuring traffic density. Up to four sensors can be connected to one box.
Measurement cross-section: Device for measuring traffic density to which up to four sensors can be connected.
Graphic overview of a street section in the form of a site plan with CS and DS indicated. Also used to refer to a group of interdependent LED VMS that are switched simultaneously. Also known as an ad-hoc circuit.
Alternative designation for LED VMS or sign.
Flashing lights of type WL7 with 300 mm diameter for advance warning in compliance with class L9H or L9MO3.
Standardised trailer with variable message signs consisting of two or three signs including advance warning lights.
Variable message sign that can be activated, changed or deactivated if necessary.
The central unit is a web-based program that evaluates the data transmitted by the control sections, generates the commands for the display sections and documents the display states. The central unit must be kept in a data centre (OC) that is permanently staffed (365 days a year, 24 hours per day) and provides monitoring and support in compliance with the EU standard contractual clauses. The data centre must agree to be a contractual dataprocessor and comply with the corresponding regulations.
