Evaluation of New Technologies for Traffic Monitoring

Increasing rush-hour congestion on the interstate system has necessitated the evaluation of Intelligent Transportation Systems (ITS) instrumentation to keep the traveling public informed of traffic conditions and commute times. The latest traffic monitoring technology takes advantage of the number of Bluetooth devices carried by the public (phones and headsets) as well as newer vehicles that incorporate Bluetooth capabilities. Bluetooth radio ranges are generally limited to 30 feet; however, new devices on the market can detect Bluetooth emissions from as far away as 250'. Electronic devices typically have an "electronic" serial number known as a MAC (Media Access Control) address. Bluetooth monitoring detects this identifier at Point A and places the MAC in a database. The mean travel time can be calculated if that same address is detected at Point B. Privacy is assured since any one MAC address is not tied to a specific owner. Side-fire radar has been in use for some years but has been shown to be useful in terms of its ability to provide vehicle length, lane occupancy, point speed and direction. Studies have shwon that side-fire radar provides reliable data under ordinary circumstances. Accuracy appears to decline with increasing congestion as would be found in a work zone. An important point to consider with both of the technologies to be evaluated is that neither are intrusive nor do they require specialized installation procedures as would be found with standard traffic monitoring devices such as loop detectors.
