Abstract
The link between road infrastructure and use energy has not been,studied in depth , particularly as the legitimate societal expectations for transportation are primarily related to efficiency and safety. The environmental emergency implies to explore new trends as minor optimization of the road to reduce the energy use. This thesis aims to develop one of these optimization by improving the poten-tial of eco-driving road infrastructure. This will be achieved by modeling the effect on the energy spent by vehicles on a road of the adequacy between their dynamics, geometry and the sectioning in speed of the infrastructure. A four steps methodol-ogy has been developed to assess speed sectioning. The first step is to proposea criterion usable by road managers to rapidly detect Misplaced Speed-sectioning Position (MSP). The second step quantifies the energy cost of a MSP for a particular vehicle and the optimal position of the speed sectioning for an eco-driver. The outputs of these two steps yield information to the manager who can propose a new speed sectioning layout taking into account traffic and road configuration. The third step of the methodology involves a traffic flow simulation enabling an enhanced energy evaluation of new speed sectioning, based on real traf-fic data, and modeling several driver behaviors. The fourth step is an optimization process to find the optimized speed sectioning. Experiments have been carried out in Bosnia-Herzegovina and France to demonstrate the feasibility of the methodology. The benefits are reduced energy consumption, air pollution and noise produced by braking.
