Bluetooth & Wi-Fi Technology manages traffic & airports passengers Today’s traffic with increased demand for mobility, safety and environmental friend- ly travel, requires smart and innovative solutions to optimise and enhance traffic flow. With proven technologies like Bluetooth and Wi-Fi tracking, the cost for col- lecting detailed data for travel time, origin and destination, traffic flow, queuing etc. has decreased significantly compared to traditional technologies like camera detec- tion. Bluetooth and Wi-Fi sensors are easy to deploy and maintenance cost are close to zero. It gives municipalities & road authorities a range of new possibilities to collect reliable traffic data.

DENMARK - BLIP Systems, a privately held possible to analyze, improve/change/act and wireless technology company with headquar- evaluate on an ongoing basis. ters near Aalborg, , has developed a complete solution for tracking road traffic and passengers in airports, called BlipTrack™ and the solution is deployed numerous places around the world.

BLIP Systems Headquarters in Denmark popular. More and more people use smart phones with both built-in Bluetooth and The vision at BLIP Systems is not only to Wi-FI and at the same time, more and more deploy Bluetooth and Wi-Fi sensors, but also cars have installed hands-free systems. to integrate with other data sources already Compared with other traffic data collection installed like ANPR cameras radars & loops. technologies, BlipTrack™ has some By doing so, data are available from one significant advantages, such as cost per single interface and analysis can be made measurement point due to: across different sensor technologies. • Sensor price itself What is Bluetooth? • Fever sensors are required per location.

Bluetooth is a wireless technology that allows personal One sensor covers multiple lanes and in computers, lap tops, cell phones and other electronic both directions. devices to communicate with each other to transfer • Installation is cheaper - BlipTrack™ information/files from one device to another. It uses radio waves and is designed to be a secure and sensor is road side based (sensors are inexpensive way of connecting and exchanging ususally mounted on light poles etc.) information between devices wireless and does not require diversion of traffic. • Typical installation is less than 1 hour Real data improve the way traffic planning • No maintenance of sensor, no moving are carried out – today planning are parts, no lenses to clean. normally based on assumptions, simulations • Measures 24/7 in all weather conditions. and manual/automatic short term traffic surveys (writing down license plate numbers By using 3 Bluetooth antennas the etc.).

By using a cloud based solution, users don’t have to worry about server installations, virus protection and upgrades. BLIP Systems have live monitoring of all cloud servers and take proactive actions to handle issues before they materialize into problems for the customer.

BlipTrack™ is used to help the general public by improving the flow of the traffic by measuring average driving times, not to track individuals. The Bluetooth Address is encrypted in the sensor using a one way hash algorithm, making it impossible to relate the Bluetooth address of a device to an individual.
