First, an extensive literature search will be conducted to determine the various security indicators that have already been proposed. Each of these indicators will be a detailed analysis in order to judge their relevance and determine their applicability in the context of microsimulation.
Based primarily on the results of first part and based on data from the microsimulation, the development of a relevant indicator will be realized. This will be done by determining the importance and influence of each of these data on the level of security that exists in the relationship between two vehicles. A detailed study of behavior patterns used by microsimulation will be necessary. The limits of the indicator should also be clearly determined.
Once the method of calculation of this indicator is established an interface with the simulation software AIMSUN (developed by the Polytechnic University of Catalonia) will be programmed to automatically obtain this indicator.
The development of this interface has been executed, the assessment of the safety level of a section of the motorway bypassing the city of Lausanne will be performed based on an existing and already calibrated model. A comparison will be made with the accident data to determine the level of correlation between the areas designated as particularly dangerous by the microsimulation and those which are dangerous in reality.
After this validation phase, the security indicator will be applied to several scenarios of telematics application.
Finally, a series of conclusions will be drawn and proposals for use in the safety analysis will be proposed.
