The main goal of this paper is to develop a distance to line crossing (DLC) based computation of time to line crossing (TLC). Different computation methods with increasing complexity are provided. A discussion develops the influence of assumptions generally assumed for approximation. A sensitivity analysis with respect to the vehicle parameters and positioning is performed. For TLC computation, both straight and curved vehicle paths are considered. The road curvature being another important variable considered in the proposed computations, an observer for its estimation is then proposed. An evaluation over a digitalized test track is first performed. Real data is then collected through an experiment carried out in test tracks with our equipped prototype vehicle. Based on these real data, the TLC is then computed with the theoretical proposed methods. Obtained results outlined the necessity to take into consideration vehicle dynamics in order to use the TLC as a lane departure indicator.
