N2 - Applications like automatic safe lane change and adaptive forward collision avoidance are increasingly based on connected vehicles approach. At the heart of communications-based automotive safety applications lies the need for reliable position estimation. Augmenting GPS positioning by utilizing short-range wireless and other on-board sensors improve positioning accuracy. However, the introduction of short-range signals changes the traditional GPS problem configuration and introduces new challenges. In this paper, we investigate issues relevant to positioning accuracy. We show that the lateral component of positioning error presents the majority of the overall error. We analyze the uncertainty space and describe the factors leading to lower accuracy of lateral positioning component aiming at better understanding of components forming the total error.
