A PDIE (Plan de Déplacements Inter-Entreprises) or "inter-company transport plan" involves a series of concerted measures to optimise commuting and work-related travel arrangements, aimed essentially at encouraging other means of transport than the private car.

The  PDIE Grenoble Presqu'île agreement brings together 17 of the institutions working on the Presqu'île Scientifique. These include, apart from the EMBL, ESRF  and ILL, ARM, Biomérieux, CEA, CNRS, CORYS, ERDF, GEG, GEM, Grenoble INP, Schneider, Siemens, ST Ericsson, ST Microelectronics, and the UJF.

The plan concerns 16000 individuals and an area of 250 hectares.
