Advisory Speed Computation in Adverse Weather Conditions |

|
| In this paper, we propose a novel approach to compute advisory speeds to be used in an Intelligent Speed Adaptation system (ISA). This method is designed to be embedded in the vehicles. It estimates an appropriate speed by fusing in real-time the outputs of ego sensors which detect adverse conditions with highway characteristics transmitted by distant servers. The method presents two major novelties. First, we consider that the 85th percentile of observed speeds (V85) is a practised and practicable speed in ideal conditions. We propose to modulate it in adverse conditions (top-down approach). Second, this method allows us taking into account the potential seriousness of crashes using a generic scenario of accident. With this scenario, we estimate the difference in speed that should be applied in adverse conditions so that global injury risk is the same as in ideal conditions. |
