Firstly, this section deals with the various traditional travel time collection techniques in order to provide a comparison with the Bluetooth travel time method. Secondly, the working concepts of Bluetooth and its components are reviewed in detail. The final section reviews the application of Bluetooth technology in travel time data collection. It involves the literature on the sensitivity analysis, veracity of the travel time obtained compared to other sensors and the cost comparisons.
2.1. Traditional travel time methods
Traditional travel time collection techniques include direct measurement techniques and indirect techniques. Direct measurement include automatic license plate readers (ALPR), automatic vehicle location (AVL), floating car techniques and data from global positioning system (GPS) etc., whereas, indirect estimation of travel time is achieved through various models which vary from the application of simple to complex algorithms for the estimation of stream travel time.
2.1.1. Probe Vehicles
The most common direct measurement of travel time is the floating car technique, which uses a probe vehicle to travel along the corridor to obtain the travel time (Robertson 1994). Use of GPS in such probe vehicles records the vehicle trajectory and timestamps continuously as the vehicle propagates along its route (Quiroga and…
