The purpose of this research is to demonstrate the feasibility of an automated system for medium-duration, deployable, in-the-field vehicle classification. Most temporary surveys of vehicle traffic today are done manually, typically with human observers recording traffic. Instead, we plan to employ a network of traffic sensors (NOTS), a number of small, low-cost computer nodes, each with a portable inductive loop sensor. This system can provide accurate measurements for longer duration and lower cost than is possible today. Our system will allow medium-term surveys, targeting 7-14 days. For temporary surveys like these it is essential that the system be easily deployable, not requiring investment in permanent, in-roadway sensors, but instead capable of being deployed by one or a few people in a few hours. We look at accurate vehicle classification and compare our results to ground truth taken from off-line analysis of videos, and to on-line human observations.
