The project aims to reduce the flow of diesel heavy goods vehicles transporting maritime containers between the Grand Maritime Port of Marseille and Nord Isère, thus enabling the reduction of GHG emissions and air pollutants from freight transport in the territories crossed, by promoting and developing multimodality and inland freight transport. Indeed, alternatives to road use in diesel vehicles exist but remain largely underutilised. River and rail infrastructure exists and is able to meet needs. It will therefore be necessary to analyse and remove the brakes on the use of alternatives to the road in PL Diesel on the flow connecting the GPMM and the Nord Isère. This support to greening is innovative in that it mobilises all stakeholders in the sector around a defined flow. It seeks to understand the specific brakes and locks of each link in the sector, characterised by an important subcontracting chain. It is therefore necessary to carry out a study allowing the knowledge of the flows concerning the transport of containers on the Rhône Saône axis more particularly between the port of Marseille and the international logistics hub of Chesne/north Isère on the transport axis Lille-Paris-Lyon-Marseille).
