California deploys TrafficCast’s Bluetooth-based monitoring system


Wisconsin-based developer of travel time collection systems TrafficCast has announced the successful implementation of its market-leading BlueTOAD Spectra Bluetooth sensor detector technology at the City of Diamond Bar in California.

TrafficCast provides travel time forecasting, road speed monitoring, and other traffic-related information, with technology, applications and content, based on advanced digital traffic data. Used as the foundation for traffic management and performance monitoring, the company’s BlueTOAD Spectra system is a suitable resource for cities such as Diamond Bar that want to continuously evaluate traffic operations and provide real-time traveler information to the public. Diamond Bar has deployed the proven BlueTOAD Spectra travel time technology to enhance and optimize its traffic network, while achieving optimal return on investment (ROI).

The City of Diamond Bar has strategically implemented the BlueTOAD travel time system throughout the city to manage the impact of commuter traffic, school zone or seasonal effects on travel-times, and peak-hour speeds.

TrafficCast’s original BlueTOAD (Bluetooth Travel-time Origination and Destination) system monitors anonymous Bluetooth signals from mobile devices in vehicles to determine travel times, road speeds and vehicle movements.

However, when a modern smartphone or navigation device pairs up to a vehicle, it is rendered undiscoverable.

The company’s next-generation, BlueTOAD Spectra system is able to detect that undiscoverable device, adding significantly to Bluetooth match counts.

With the number of states legislating the use of ‘handsfree’ mode in vehicles, the new dual-radio detector, couples ‘discoverable’ (unpaired) and ‘undiscoverable’ (paired) Bluetooth detection, and has been proven to offer the highest match rate in the industry, and significant increases in Origin/Destination metrics. The BlueTOAD data can then be analyzed with the company’s BlueARGUS software platform.

“Using the BlueARGUS suite of reporting tools to create Origin & Destination (O/D) studies and Travel Time Reliability reports will assist us in determining the best locations for our proposed adaptive traffic management system,” said Christian Malpica, Diamond Bar’s associate engineer. “This is also an extremely useful system to monitor before-and-after travel times as we continue to enhance our traffic management system network, another step toward confirming our congestion mitigation strategies, and overall investment in traffic operations.”

Local TrafficCast distributor NexTech Systems’ president, Janna McKhann, noted, “Diamond Bar is our first implementation of BlueTOAD Spectra and the BlueARGUS traffic analytics software in Los Angeles County. We’re looking forward to working with the city to assist in their development of travel-time data analysis and then sharing those insights with other neighboring regions.”
