Measuring the amount of traffic and the classification of vehicles continue to be the principal needs when it comes to traffic measurements. Nodeon provides reliable traffic measurement and vehicle classification solutions readily integrated in the cloud-based Nodeon Smart City platform.
If the aim of traffic measurements is to determine traffic volumes and vehicle classification, the market offers several different technologies which resolve this issue, each with their own pros and cons.
In addition to measuring the number of vehicles, the user also has to decide where and how to transfer the measurement data, where to store it, and what kinds of analyses will be performed on the basis of it – in other words, how to present the data.
Nodeon’s traffic volume measurement solution is a productised solution which allows the integration of several different measurement techniques. The data is transmitted from the field to the Nodeon Smart City cloud, which provides customers with a centralised point for the management and analysis of the measurement data.
The presentation of hourly traffic volumes in the Nodeon Smart City cloud is updated every five minutes.
SUPPORT FOR SEVERAL MEASUREMENT SOLUTIONS
Inductive loop sensors
Inductive loop sensors, installed beneath the surface of a road, are a traditional and still reliable way of carrying out traffic volume measurements and vehicle classification. The sensor reacts to changes in the electromagnetic field when a vehicle drives over a loop. The technical implementation method makes the sensor a reliable way by which to measure traffic volumes in all weather conditions and during different seasons. Nodeon’s solution can be integrated with both new and old loops already installed in the ground.
Microwave counters are a common way to carry out traffic measurements, particularly in moveable counts, due to their easy installation. The counter can be installed by the side of the road or street, and the installation does not disturb traffic in any way. The counting based on microwave technology produces data on the direction, speed and lane of vehicles, in addition to the volume of vehicles. Nodeon’s solution allows for the integration of microwave counters equipped with open interfaces, in which case the data they produce is transmitted automatically to the Nodeon Smart City cloud solution.
The technical implementation of measurements in all of Nodeon’s solutions is based on a productised field solution which is integrated with the identification technology in use. The field solution collects data from the software interfaces of the measurement devices and sends this to a programmable unit installed in the field, which carries out encrypted transmission to the Nodeon Smart City platform.
The Nodeon Smart City platform provides a real-time situational picture of the traffic situation, key indicators on the traffic flow and ready reporting tools based on the measurement data. The raw data generated by the measurements can also be uploaded to the user’s computer for their own analyses.
