Variants & Options


TOPO.lx is able to classify on multilane roads with two multibeam-LIDAR sensors. One sensor detects the lateral height profile and allocates the vehicles to the lane, the other sensor detects the vehicles from the back. The measured data is put together to make an exact classification possible.

For an exact classification of traffic volume, installation on the mast. This variant with an integrated charging device can be used very well as a permanent counting station.

Ideally, the installation height of the should be 2.50 m. The device can be mounted on masts ranging in diameter from 76 to 150 mm using the universal mast bracket.


Integration of the system in a standard guide post for installation along roads outside city limits. This implementation fits optimally in the appearance of the street.

A foundation receptacle into which the device can be inserted is necessary for the installation of the TOPO.slp.

The small box can be simply installed at the edge of the road by just one person. Thus it can be used quickly and in a variety of ways to classify the amount of traffic.

The is to be installed at a height of approximately 1.00 m. It can be mounted on all masts commonly in use.

In addition there is the  variation TOPO.bigbox which is the same device but with a bigger battery.

Option: Solar Power Supply

Please note:

It has to be ensured that the solar panel is placed at a location where it’s receiving direct sunlight. Due to the high fluctuation in hours of sunlight per day at different times of year, the sole power supply via a solar panel cannot be guaranteed. Therefore, RTB recommends using an additional rechargeable, replaceable battery to ensure the operation of the device throughout the year. If the power supply is via solar energy, the solar panel must be cleaned at least once a year.

Consists of:

  • solar module
  • solar regulator
  • accumulator cabinet

Option: GSM Modul

Automatic Data Transfer

The traffic data collected by the devices can be transmitted via GPRS to a server on the internet. The prerequisite for this is the integration of a GSM module and the provision of a SIM card by a mobile telephone company. The transfer rhythm of the data to the server can be configured at will.

Location Identification via GPS

A GPS module connected to the GSM interface is available. The location coordinates of the device are stored along with the collected traffic data in each data set. The current position of the device can thus be determined precisely. This makes it possible to take special measures in case of theft. If a device is removed without authorization, the GPS module automatically sends an alarm message along with the current position.

Option: Comfortable Analysis

Comfortable Analysis:

With the personalized analysis program DD.web one can access the data of all devices from every computer with internet access. The data can be analyzed simply, quickly and comfortably and then be processed in the form of a presentation.

For this a wide variety of analysis possibilities are available:

  • Calculation of speed (Vav, V85, V15 and Vmax)
  • Vehicle classification (complexity depending on the configuration of the device)
  • Conversion into car units
  • Analysis of the average daily traffic (ADT).

The data can be imported either automatically via the GSM module or manually within the program. Diverse export variants are available to use the data in other programs.
