1. A computer-implemented method of monitoring vehicle traffic along a roadway comprising:
- initiating, in a first sensor disposed at a first location along a roadway, a first inquiry scan according to a Bluetooth standard;
receiving, in the first sensor and at a first time, a first inquiry response according to a Bluetooth standard from a mobile device, the first inquiry response including a media access control address of the mobile device;
storing, in the first sensor, a first device identifier identifying the mobile device based on the first inquiry response;
storing, in the first sensor, a first sensor identifier that identifies the first sensor;
associating the first device identifier with the first sensor identifier and a first time stamp that reflects the first time;
initiating, in a second sensor, a second inquiry scan according to a Bluetooth standard, wherein the second sensor is disposed at a second location along a roadway;
receiving, in the second sensor and at a second time, a second inquiry response according to a Bluetooth standard from the mobile device, the second inquiry response including the media access control address of the mobile device;
storing, in the second sensor, the first device identifier identifying the mobile device based on the second inquiry response;
storing, in the second sensor, a second sensor identifier that identifies the second sensor;
associating the first device identifier with the second sensor identifier and a second time stamp that reflects the second time;
identifying that the first device identifier is associated with the first sensor identifier and with the second sensor identifier; and
based on having identified that the first device identifier is associated with the first sensor identifier and the first time stamp as well as with the second sensor identifier and the second time stamp, deriving at least one vehicle traffic statistic based on the first time stamp, the second time stamp, the first location, and the second location.

Abstract
Devices, systems, and methods for monitoring traffic, such as vehicle traffic on a roadway, using identification information acquired using a Bluetooth protocol. A sensor is configured to scan for discoverable Bluetooth devices within a flow of vehicle traffic and to create a log of identified Bluetooth devices. A system includes multiple sensors at known locations along a route and is operable to identify a Bluetooth device identified at multiple sensors.
