Real-Time Estimation of Emissions Emerging from Motorways Based on Macroscopic Traffic Data

In this paper a complex traffic emission modeling approach is suggested: based on the considerations of macroscopic traffic flow modeling and an average speed emission model, a macroscopic emission model is formed. The proposed methodology leads to two functions to evaluate traffic emission: a model for actually realized emissions and one for the emission level of traffic. The former one is useful for a more exact estimation of emissions relative to inventory methods; the latter one is for the analysis of optimal traffic control objectives. The introduced functions are validated in VISSIM/MatLab environment on a real motorway segment model located in Hungary.
