Vehicle Classification
Automatic vehicle classification (AVC) is a critical, integral part of electronic toll collection (ETC) and traffic management systems. Sensor Line offers SL-Road System Basic, a turn-key vehicle classification solution that is highly accurate and reasonably priced for single-lane and multilane free-flow roads and stop-and-go tolling stations. SL Road System Basic is integrated with Sensor Line's long-life and high-accuracy fiber optic axle sensors, as well as it can be combined with the other non-intrusive and intrusive vehicle detection sensors, such as lidars, optical curtains, and inductive loops. The experimental classification accuracy for the system is better than 99.9% for post-classification and better than 98% for pre-classification systems.

Vehicle Counting
Vehicle counting by axle detection is the most stable and common measurement of road usage. The information and data from the counted vehicles support all major areas of road traffic monitoring such as Intelligent Transportation Systems (ITS), Electronic Toll Collection (ETC), highway planning as well as traffic management and traffic analysis. Sensor Line's in-road traffic sensors with their fiber optic sensor technology are the most accurate and reliable axle counting sensors on the market. The precise acquisition of vehicle characteristics enables road operators to monitor and control traffic flow in real time and at minimal cost.
The different types of Sensor Line's high-performance sensors are designed for various traffic monitoring applications in different areas of use.

Cyclist Counting
Modern cities' approach to sustainable mobility concepts calls for innovative ideas. Many initiatives plan to provide more safety and space for vulnerable road users. The detection of bicycles and similar vehicles is an important step in designing environmental improvements as well as planning overall capacity and addressing safety issues in urban traffic.
To capture this specific data, Sensor Line offers the most sensitive in-road sensor for various types of bicycles, scooters and other innovative and individual transportation.

Vehicle Speed & Speed Enforcement
Monitoring vehicles speed and enforce violations is a desired application for safety and traffic monitoring. This is becoming more and more important with regard to Vision Zero. Due to the increasing interest in monitoring and reporting on road performance, road operators are being asked to collect and report data on where, how often, for how long and to what extent roads are congested. At the same time, safety and environmental studies are interested in the relative distribution of vehicle speeds and the number and type of vehicles that are speeding.
Sensor Line's SL PUR and SL SPZ sensors are ideal for single vehicle speed applications and enforcement or the combination of multiple applications, such as automatic classification of speeding vehicles.

Vehicle Volume
Detecting vehicle volumes is essential for all intelligent transportation systems (ITS) and traffic analyses. The measurement of vehicle volumes and their composition (class, speed, number, right of way, gaps, congestion, ...) is also one of the basic functions of traffic management and highway planning. Sensor Line’s in-road traffic sensors ensure the highest possible quality in the correct collection and provision of vehicle volume data. The insights gained from the collected data are important for shaping a targeted traffic policy for passenger and freight transport, both for public clients and for the private sector (public-private partnership - PPP).
Sensor Line road traffic sensors can be used in various fields of application in the area of vehicle traffic.

Occupancy / Headway / Gap / Congestion Determination
Determining traffic density is the key to analysing existing traffic routes and creating new traffic concepts. Most right-of-way and gap information is collected and reported as part of special studies and capacity analyses, for which short-term counts are very well suited. Sensor Line's permanent traffic monitoring sensors are easy to install and are suitable for much more meaningful long-term monitoring as well as short-term counting.
The results can provide important information before or during planning. Not only for the future dimensioning of roads and maintenance planning, but also for safety and economic reasons.
