Study on the cost-effectiveness of a probe vehicle system at lower polling frequencies

One serious problem of continuous large-scale data collection with probe vehicle is the dilemma of balancing the cost economization and system reliability improvements. The polling frequency is found to be one of the major factors that determine the operation cost of a probe vehicle-based traffic data collection system. This paper focuses on evaluating the cost-effectiveness of a probe vehicle system at various space-based polling intervals, with the purpose of data collection on providing roadway travel time estimation at certain reliability. The proposed optimization framework concentrates on the least total operation cost through a combining consideration on the polling frequency and the required probe size, which gives a simple and valuable solution on the issue of cost-effective traffic data collection.
