Cobb County and Fulton County in Georgia, US, have rolled out TrafficCast’s Bluetooth Travel-time Origination And Destination (BlueTOAD) system.

The counties have implemented BlueTOAD to improve major arterial roadways efficiency, reduce traffic congestion and bring down travel delays and journey times.

Cobb County traffic signal systems manager Brook Martin said that the performance-based measurement tool provides the county with a traffic data system to help support the efficient operation of its adaptive corridor management initiative.

"For example, our new traffic management centre (TMC) utilises the BlueTOAD real-time speed map and associated data as an incident management and monitoring resource to determine the effects of heavy traffic from I-75 spilling onto Cobb Parkway," Martin added.

Fulton County traffic operations manager Wyvern Budram said using BlueTOAD for reporting historical data, gathered from an archived travel-time database, the county is able to analyse valuable information to effectively manage its newly-installed adaptive signal system.

"As a result, we use BlueTOAD data to determine modifications to signal timing splits and offsets to actively manage and maintain our key arterial traffic signals," Budram added.

The BlueTOAD system collects travelling data from the mobile devices connected to bluetooth, such as headsets, mobile phones, navigation units and in-vehicle infotainment systems, to analyse timestamp.

The technology then calculates the travel time using the analysed data and also identifies the route behaviour of the vehicles based on its movements.
