## Saturation in a Markovian parking process.(English)Zbl 1012.60087

Summary: We consider $$\mathbb{Z}$$ as an infinite lattice street where cars of integer length $$m\geq 1$$ can park. The parking process is described by a 0-1 interacting particle system such that a site $$z\in\mathbb{Z}$$ is in state 1 whenever a car has its rear end at $$z$$ and 0 otherwise. Cars attempt to park after exponential times with parameter $$\lambda$$, leave after exponential times with parameter 1 and are not allowed to touch nor overlap. We define and study a jamming occupation density for this parking process, using the quasi-stationary distribution of a Markov chain related to the reversible measure of the particle system. An extension to a strip in $$\mathbb{Z}^2$$ is also investigated.
