This system uses Bluetooth for electronic terminals (car navigation systems, smartphones, etc.) mounted on traveling vehicles. ® Is received by receivers installed at regular intervals on the side of the road, and it is possible to calculate the exact required time even during traffic stagnation based on the difference between the passing times at each receiving point. In order to determine the passing time of each vehicle, unique information called MAC address * is used. The calculated travel time can be provided on a simple information board or on a website.

* About MAC address

To calculate the time required by the customer, the received Bluetooth ® We will use a part of the 12-digit unique ID that is assigned to network devices such as smartphones, which is called the MAC address included in. Specifically, after deleting two digits from the 12-digit ID, the character string converted by the hash function used for further encryption is collected and statistically processed as a temporary ID for calculating the required time. You. The personal ID cannot be identified directly from the ID collected here, and since the original MAC address data is not possessed, the personal information of the customer does not leak to the outside.
