  We introduce a continuous space limit of the Vertex Reinforced Jump Process
(VRJP) in dimension one, which we call Linearly Reinforced Motion (LRM) on
$\R$. It is constructed out of a convergent Bass-Burdzy flow. The proof goes
through the representation of the VRJP as a mixture of Markov jump processes.
As a by-product this gives a representation in terms of a mixture of diffusions
of the LRM and of the Bass-Burdzy flow itself. We also show that our continuous
space limit can be obtained out of the Edge Reinforced Random Walk (ERRW),
since the ERRW and the VRJP are known to be closely related. Compared to the
discrete space processes, the LRM has an additional symmetry in the initial
local times (initial occupation profile): changing them amounts to a
deterministic change of the space and time scales.
