The world’s most trusted permanent bike counter, designed for urban cycling.

Eco-Counter’s Urban ZELT Inductive Loop system is the world’s leading technology for permanent on- and off-street bike counting. The system is perfect for obtaining trends over time and allows for the comparison of bike trips over consecutive months, seasons or years. The ZELT loop precisely analyzes the electromagnetic signature of each bicycle wheel using 13 differentiation criteria.

The ZELT’s unique SIRIUS algorithm allows the system to detect all types of bicycles with extreme precision. When the loops are installed on a shared road, the system will accurately count bikes while ignoring cars motorcycles and larger vehicles. The system can be configured to count on any type of cycling facility (shared road, bike lane or protected bike path).

Designed for Shared Roads:
The Urban ZELT is used to accurately count cyclists in mixed traffic conditions. The system is ideal for deploying on bike boulevards, shared lanes and on-street bike lanes.

Measures the Direction of Travel and classifies speed of cyclists:
In San Francisco, several bidirectional counters have been installed to monitor cycling volumes on contra-flow bike lanes. The ZELT counter also enables to classify cyclists according to their speed. Cycling count data with direction information and speed classification can help in planning safe routes and the justification of new infrastructure investment.
