We present a framework to integrate macroscopic traffic flow models with microscopic emission and fuel consumption models. Since macroscopic traffic flow models do not provide the acceleration as an output, while microscopic emission and fuel consumption models require both the instantaneous speeds and accelerations as input, we describe how to generate these variables. In particular, we consider the macroscopic traffic flow model METANET and the microscopic emission and fuel consumption model VT-micro. In order to integrate these models, we propose a method to generate from the METANET model the spatial and temporal speed-accelerations pairs and the number of vehicles subject to them, which are required as input by VT-micro. The integration of the models results in a new macroscopic emission and fuel consumption model called the VT-macro model.
