The aim of this presentation is to propose a new event-based mesoscopic model, fully consistent at a macroscopic scale with the LWR model. This model is parsimonious, has a low computational cost while keeping an individual tracking of vehicles. It is ready for dynamic trafficassignment applications. It can also be easily combined with any microscopic models to propose a bi-level traffic flow representation on networks. This model overhauls the link traffic flow model early proposed by Mahut (2003) by integrating heterogeneous vehicle characteristics and moving bottlenecks treatment. It also introduces a simple node model that (i) generalizes the supply allocation scheme at merges proposed by Daganzo, (ii) naturally respects the FIFO rules at diverges and (iii) accounts for traffic signals timing. This model reproduces at an individual scale the global behavior reproduced by classical macroscopic node models and notably merge ratios
