Traffax Inc. Conducts July 4 Study of Vehicle and Pedestrian Traffic Flows with D.C. Dept. of Transportation
The preliminary results of this demonstration show the potential of the Bluetooth technology to effectively measure travel conditions in urban areas. The data, which was collected along Seventh Street, N.W., shows the influx of pedestrians before the beginning of the
The traffic data collected by the Traffax equipment can be used to manage vehicle and pedestrian traffic flows in various applications such as retiming traffic signals, directing motorists and pedestrians to less congested corridors and transit stations, and dispatching appropriate personnel to bottleneck locations. The information collected for DDOT during the
The Traffax data collection system, known as BluFax, matches Bluetooth addresses observed at successive installations, to obtain travel time samples. Travel time is increasingly being used by transportation officials to judge the quality of service they are providing, as opposed to more subjective measures of congestion, which have been used in the past. Until now, it has been impossible for transportation engineers to accurately measure the travel times of either vehicles or pedestrians in urban areas.
Unlike other traffic monitoring methods, which might threaten personal privacy, the Traffax equipment operates in a manner that protects the public from potential abuse. The Bluetooth addresses being received cannot be associated with specific individuals, vehicles, or devices. The received data is used to produce statistical summaries that ignore the movements of any particular electronic device. The records of specific addresses are discarded during processing. As a result, the privacy issues associated with technologies such as cell phone location, closed circuit television monitoring, and license plate reading, are avoided.
BluFax technology was initially developed at the
