Title:

Analysis of Low Cost Bluetooth-Plus-WiFi Device For Travel Time Research

Accession Number:

Abstract:

The focus of many researchers in travel time studies is to gather sufficient data to predict accurate travel times within a road network with limited financial constraints. Using Bluetooth and Wi-Fi (BT) to track media access control (MAC) addresses in travel time studies is a fairly recent but popular low-cost communication protocol. Many researches rely on commercially developed BT detecting devices from local transport agencies that are restricted to certain locations. This paper presents one of the low cost BT detecting devices developed by the Nebraska Transportation Center (NTC), referred to as generic Bluetooth (gBT). This is presented as an alternative to the robust but fixed commercially developed BT devices. The study objectives are to present the assembling components of the gBT and ascertain the reliability of the gBT collected data for researchers. The gBT is modular, readily adaptable, low cost, and can be easily assembled and disassembled. Travel times were collected using the gBT reader and a Global Positioning System-probe vehicle for 15 hours in 3 consecutive days on a 2-mile arterial road segment in Lincoln, Nebraska. The GPS data was used as the average “ground truth” to evaluate the reliability of the gBT. It was shown that the gBT is viable for determining link travel times. There was an average of 4% deviation of median values compared to the GPS data and relatively wide variations. However, theoretical lognormal distribution fit both data, and there were no statistically significant differences at the 95% confidence level between the mean travel times from both systems.
