This paper introduces a new model for describing intersections in road networks, whose load dynamics is governed by the Lighthill–Whitham–Richards model. More precisely we define a solution for intersections using a multibuffer, i.e. a set of buffers, one for each outgoing road. We compare the obtained dynamics with those of some models previously introduced in the literature. In particular, we are able to respect the preferences of drivers and to not block the intersection when only one outgoing road is full. This improves some weaknesses of previous models

Abstract
This paper introduces a new model for describing intersections in road networks, whose load dynamics is governed by the Lighthill–Whitham–Richards model. More precisely we define a solution for intersections using a multibuffer, i.e. a set of buffers, one for each outgoing road. We compare the obtained dynamics with those of some models previously introduced in the literature. In particular, we are able to respect the preferences of drivers and to not block the intersection when only one outgoing road is full.
