Faculty Civil Engineering and Geosciences Department Transport and Planning Date 2012-12-31 Abstract In the last decade many multi class kinematic wave (MCKW) traffic ow models have been proposed. MCKW models introduce heterogeneity among vehicles and drivers. For example, they take into account differences in (maximum) velocities and driving style. Nevertheless, the models are macroscopic and the ow is modeled as a continuum flow, without tracing individual vehicles. The first MCKW models were simple extensions of the mixed class kinematic wave model [1, 2]. For example, Wong and Wong introduced a kinematic wave model with unequal velocities for all classes [3]. More recent MCKW models take into account that some vehicle classes use more road space per vehicle than others and that this space occupancy may change if the velocity changes [4, 5, 6, 7]. Recently, frameworks were proposed to assess fundamental relations [8] and to assess car following traffic ow models [9, 10]. Some important properties of MCKW models have been analyzed before [3, 4, 5, 11, 12, 13], but no consistent assessment framework has been developed yet. Our main contribution is the introduction of a framework for the assessment of MCKW models. It is applied to analyze whether MCKW models have certain important properties. The framework consists of a set of requirements (see Section 2) and a generalized MCKW model (see Section 3). In the full paper we show that all MCKW models known from literature fit in the generalized model. In Section 4 we apply the framework and assess all MCKW models. We conclude that only few models have all desirable properties. Finally, in Section 5 we give an outlook for the full paper.
