Bluetrace boosts detection rates without privacy concerns

Vehicle counting and travel time determination is said to be easier and more accurate using Bluetrace which detects both Bluetooth and Wi-Fi signals from motorists smart phones. According to the Netherlands-based company's UK importer Rennicks, only 10% of mobile phone owners have Bluetooth activated whereas most have the Wi-Fi switched on leading to a hit rate of 98% which increase accuracy and granularity while maintaining the anonymity of a non-ANPR system.

Vehicle counting and travel time determination is said to be easier and more accurate using 8151 Bluetrace which detects both Bluetooth and Wi-Fi signals from motorists smart phones.

According to the Netherlands-based company's UK importer Rennicks, only 10% of mobile phone owners have Bluetooth activated whereas most have the Wi-Fi switched on leading to a hit rate of 98% which increase accuracy and granularity while maintaining the anonymity of a non-ANPR system. It is also said to be around half the cost of an ANPR system and to require almost zero maintenance.

Algorithms in the system are said to filter out multiple signals from transit users and other anomalies, it can be configured to signal an alert if the traffic speed drops below a pre-determined figure and road workers can be provided with tags to track their whereabouts. The system can be mains or solar powered while for temporary installation battery powered versions are available.

    Spectra is the latest version of BlueToad, TraffiCast’s Bluetooth detection technology, which can detect Bluetooth signals even when they are in a non-discoverable state – a move that can boost downstream matches by almost a factor of three. Once devices are paired – typically a mobile phone pairing with an in-car system such as a hands-free device, the Bluetooth signal is no longer discoverable by external devices – except by Spectra that is.

Solar power has been relatively slow in entering the transport sector, but a current blossoming of activity bodes well for the large-scale harnessing of an alternative energy that is zero-emission at source and, in practical terms, infinitely renewable. Traffic management and traveller information systems, and actual vehicles, are all emerging as areas for deployment. Meanwhile roads themselves are being viewed as new-style, fossil fuel-free ‘power stati
