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.

    Bluetooth and Wi-Fi offer new options for travel time measurements
    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

    Collecting speed and travel time data without using roadside infrastructure could offer new possibilities to cash-strapped road authorities. Streaming video may be useful for traffic controllers to monitor incidents and automatic number plate recognition may be required for enforcement, but neither are necessary for many ITS functions. For instance travel times, tailbacks, percentage of vehicles turning, origin and destination analysis can all be done using Bluetooth and/or WI-Fi sensors and without video o

    Rennicks UK, in conjunction with Bluetrace, is using Traffex 2015 to launch a new traffic management system which it says is a significant leap forward in the battle to improve safety and reduce congestion. The system, developed in conjunction with Bluetrace, uses the most sensitive Bluetooth and wi-fi technology on the market to monitor and measure traffic movement from the roadside by connecting to devices inside vehicles. The data is transmitted to a central location to present a clear, real-time p
