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.

Cellint measures speed and travel time without roadside infrastructure

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
