Abstract

Traffic efficiency if one of the key applications of the connected vehicle technology, which uses moving cars as nodes in a network to create a Vehicular Ad hoc Network (VANET). The nodes act as mobile traffic sensors. The technology holds promise for enhancing urban and highway mobility. It is cost-effective alternative to the existing fixed location traffic sensing technologies such as inductive-loop detectors and video image processing systems. In this paper we survey the emerging applications of VANETs for traffic efficiency. We considered green light speed advisory systems, adaptive traffic signals, virtual traffic signals, and cooperative traffic information systems. Topics for future research are suggested. We stress the fact, that due to rebound effects the improvements in traffic efficiency will result in additional vehicle travel (generated traffic). Although net congestion reductions will most likely be observed, it is important to account for rebound effects when evaluating initiatives related to traffic efficiency.
