Which speed display panel is right for my application?
In principle, all viasis displays are suitable for traffic calming at danger points. However, the different housing shapes and LED display options offer advantages for some applications:
For mobile use, viasis speed display panels with with smaller housings are particularly suitable, as they are easier to transport and easier to mount.
For fixed installation, e.g. at the entrance to a town or near a school, the larger viasis PLUS speed display boards are also suitable. The large display areas are visible even at great distances and additional LED texts further enhance the effect of the displays. We will be happy to advise you on the selection of the right system for your application. Please contact us by email at email@example.com or by phone at 02171/504930.
How much will a viasis speed board cost me?
We offer viasis displays in different price segments. We will be happy to send you our price list or specific offers tailored to your needs. Please contact us by phone at 02171/504930 or by email at firstname.lastname@example.org.
Where should the speed display panel be placed?
Wherever there is a risk of danger for weaker road users. Especially where speed limits are disregarded, speed display boards are effective.
In the municipal sector, these are often school routes, the vicinity of kindergartens and senior citizens' homes, or intersections that are difficult to see.
In-house, viasis speed displays are used to defuse danger spots and make it safer to work on the premises.
Can private individuals also set up speed display boards?
The use of a speed display on private property or private roads is possible without restriction, because the following applies: Setting up a speed display board privately is permitted -as long as it is on private property.
If a viasis speed display is to be operated on public roads, you need a permit from the responsible authority. Here you are not allowed to set up a speed display board as a private person without prior approval.
What mounting options do I have?
The speed display boards are particularly easy to mount. Our one-man mounting set can be used flexibly on all common sign or lampposts. It is theft-proof with a special tool and an additional padlock and very durable thanks to the robust material. If no pole is available at the desired installation location, we offer our customers alternative tripod solutions and a mobile trolley for equipment mounting.
If you have any questions about the different mounting solutions, please do not hesitate to contact us.
What traffic data analysis options do I have?
With viagraph, the software for data evaluation, you have the possibility to collect and evaluate data such as average speed, maximum speed and the V85 speed ratio. Tables, pie charts and bar charts are created on the basis of Excel. A total of 425,125 speed values can be stored in the memory.
We will be happy to send you an example data evaluation in Excel format.
What is the range of the viasis speed table?
In the free field, normal cars are measured on average in a range of more than 120m. The larger the vehicle, the higher the range. For trucks the range increases by about 50% -for motorcycles it decreases by 50%. The detector reaches the highest range at a mounting height between 2m & 3m.
Does the road have to be completely clear for the speed display panel to measure?
The clearer the view, the higher the range of the speed detector. High buildings at the edge of the roadway or dense and high planting can worsen the range and lead to scattering losses. This is only occasionally the case, but should always be considered when measurement errors are noticed. Rarely is the cause due to the microwave detector. A clear view also offers less distraction and increases the perception of the already clearly legible speed display panels.
From what distance are the speed signs with smiley easily readable?
Thanks to the modern LEDs and the size of the speed displays, the display boards can be read safely even at a distance of over 120m. Due to the strong LEDs, the displays are still clearly visible even in sunlight.
How long is the speed visible on the display?
This is where the high range viasis comes into play: The first measurement and display takes place at about 120m. This gives the driver enough time to adjust the speed and receive positive feedback. Measurements are taken and the displayed speed is updated at a frequency of 1.5 seconds. The last measured value is displayed for about 3 seconds.
At what temperatures can the viasis speed display panels be operated?
We recommend an operating temperature from -20°C to +70°C. Outside these limits, no warranty can be given on the high-frequency units.
Will the speed display panels work in rain and snow?
Nothing stands in the way of commissioning in different weather conditions. Rain and snow can possibly lead to attenuation losses of the radar. The system is insensitive to rain, since the housing is splash-proof with the noise protection class IP64 according to EN 60529.
How susceptible are the speed display panel systems to interfering signals?
High measurement accuracy: Incorrect speed values due to radio interference are almost impossible. The use of a multi-channel Doppler trasceiver protects the measurement process.
