Bluetooth beacon

Calculation of Individual and Average Travel Times on Defined Road Segments

The principles

The Bluetooth beacon provides an optimal solution for measuring travel times and analyzing origin–destination matrices. It enables periodic calculations of average vehicle travel times across different road segments.

Easily installed thanks to its adaptable mounting kit suitable for various environments, the beacon connects via a single network cable, providing both PoE power and data transmission.

Bluetooth travel-time measurement beacons offer a unique capability to capture real-world traffic data in a non-intrusive and cost-effective manner.

By detecting Bluetooth signals emitted by onboard or carried devices in vehicles, these sensors measure the time it takes users to traverse a given segment, based on anonymized and timestamped identifiers. The analysis of this data, centralized on a server and collected during each vehicle pass near the beacons, allows the determination of Individual Travel Time (ITT). Statistics derived from these ITTs can then be used to periodically evaluate average travel times across different segments.

2 POSSIBLE VERSIONS 

• The PoE (Power over Ethernet) beacon

The Bluetooth beacon is powered and network-connected via PoE (Power over Ethernet). Lightweight and easy to deploy, this technology provides both electrical power and data transmission over a single Ethernet cable.

It comes in a polyester casing, resistant to external aggressions.

A modular mounting kit allows installation on a wall (using anchors) or on a pole (using clamps or straps).

An RJ45 cable gland is accessible on the underside for PoE.

The beacon is equipped with an omnidirectional antenna, requiring minimal installation constraints. Ideally, it should be installed at a height between 1 and 5 meters, with traffic visible from its front face.

• The OEM beacon

The OEM beacon is a version that can be connected to any host board running a Linux system.

We can provide OEM beacons with a software stack and integration support for third-party products.

The OEM beacon is high-performing, reliable, robust, and energy-efficient. It consists of a small polyester casing, resistant to external aggressions, and a DIN rail interface module to be installed inside a cabinet.

The casing comes with a mounting kit allowing installation on a wall using anchors or on a pole using straps.

The interface module allows connection via USB to the host board and via CAT5e/CAT6 network cable to the polyester casing.
