Driver Assisting by Inverse Time to Collision

The paper is proposing a specific indicator, the inverse time to collision TTC^-1, useful when analyzing the highway traffic. The advantage of TTC^-1 vs. TTC is a direct and continuous dependence with the collision risk. TTC^-1 could be used as an input in car following algorithms. Because the automate driving is yet in a research stage, a feasible application for TTC^-1 would be rather assisting the driver of the following car at the choice of the distance gap towards the first car.
