Bangkok Expands BlipTrack Wi-Fi Bluetooth Sensor Solution
The city of Bangkok, Thailand, is expanding its use of the BlipTrack queue- and flow-management sensor solution from Blip Systems to cover additional roads. The expansion will provide city engineers with travel times and congestion alerts, in order to ease traffic woes and provide drivers with real-time traffic information.

Thailand's Department of Highway (DOH) was pleased with the traffic data collected by its BlipTrack Wi-Fi Bluetooth sensors, the company reports, and is now expanding the technology to cover additional roads in Bangkok. The city has some of the worst traffic congestions in the world. Faced with the challenges of trying to ease traffic and reduce massive gridlocks, the DOH needed a solution to help provide live and detailed traffic information. To help measure and provide travel times and traffic flow, and to predict traffic build-up, the city implemented the BlipTrack solution in 2015.

"The Department of Highway wanted to measure and compare travel times on the Intercity Motorway, The Bangkok Expressway and neighboring routes in Bangkok," said JJ Nutayakul, the managing director of New Trend Development Co., in a prepared statement. "The idea was to present real-time traffic information to road users, via DOH's Highway Traffic mobile app, to help them make informed decisions when planning their trip."

The mobile app, which provides information on travel times, fastest routes and other traffic information, is continually updated, in line with the actual behavior of road users. So, by considering their route and the time they depart, motorists help to keep the traffic moving. The BlipTrack data will help to provide economic benefits through reduced travel times, fuel consumption and vehicle emissions.

"This was the first project ever in Thailand, where this kind of technology, in the traffic field, has been implemented and it has shown great results," Nutayakul said. "The client, the Department of Highway, is very pleased with how fast the installation has been, the ease of configuration and the hardware reliability."

"BlipTrack has helped Thai citizens to travel home faster during two major traffic events: Songkran and New Year holidays," said Songrit Chayanan, director of the Samut Sakhon Highway District, in the prepared statement. "The system allowed not only road users to decide route choices via travel time info online but also the Thai Highway Police to manage traffic in real time."

According to Blip Systems, BlipTrack sensors are placed at strategic points along roads. The sensors, covering roughly a 600-kilometer section of highway in and around Bangkok, detect Bluetooth or Wi-Fi devices, found in mobile phones and in car audio and communication systems. Re-identifying the devices from multiple sensors enables specific and accurate statistical information, such as travel times, average speeds, dwell times and movement patterns, to become available.

"The solution gives more accurate travel time data compared to spot speed data collected from radar and ANPR cameras," Nutayakul said. "Furthermore, the origin/destination data is used by city engineers to gain an in-depth insight into the understanding of traffic flows and the development of traffic jams, in order to optimize the road network and reduce congestion."
