  In line with its terms of reference the ICFA Neutrino Panel has developed a
roadmapfor the international, accelerator-based neutrino programme. A "roadmap
discussion document" was presented in May 2016 taking into account the
peer-group-consultation described in the Panel's initial report. The "roadmap
discussion document" was used to solicit feedback from the neutrino
community---and more broadly, the particle- and astroparticle-physics
communities---and the various stakeholders in the programme. The roadmap, the
conclusions and recommendations presented in this document take into account
the comments received following the publication of the roadmap discussion
document.
  With its roadmap the Panel documents the approved objectives and milestones
of the experiments that are presently in operation or under construction.
Approval, construction and exploitation milestones are presented for
experiments that are being considered for approval. The timetable proposed by
the proponents is presented for experiments that are not yet being considered
formally for approval. Based on this information, the evolution of the
precision with which the critical parameters governinger the neutrino are known
has been evaluated. Branch or decision points have been identified based on the
anticipated evolution in precision. The branch or decision points have in turn
been used to identify desirable timelines for the neutrino-nucleus cross
section and hadro-production measurements that are required to maximise the
integrated scientific output of the programme. The branch points have also been
used to identify the timeline for the R&D required to take the programme beyond
the horizon of the next generation of experiments. The theory and phenomenology
programme, including nuclear theory, required to ensure that maximum benefit is
derived from the experimental programme is also discussed.
