Macroscopic Modeling and Control of Emission in Urban Road Traffic Networks

Abstract

Abstract. This work suggests a framework for modeling the traffic emissions in urban road traffic networks that are described by the Network Fundamental Diagram (NFD) concept. Traffic emission is formalized in finite spatiotemporal windows as a function of aggregated traffic variables, i.e. Total Travel Distances (TTDs) in the network and network average speed. The framework is extended for the size of an urban network during a signal cycle -the size of a window in which the network aggregated parameters are modeled in the NFD concept. Simulations have been carried out for model accuracy analysis, using the microscopic Versit+Micro model as reference. By applying the macroscopic emission model function and the traffic modeling relationships, the control objective for pollution reduction has also been formalized. Basically, multi-criteria control design has been introduced for two criteria: maximization of the TTD and minimization of traffic emissions within the network.

The impact of autonomous vehicles on urban traffic network capacity: an experimental analysis by microscopic traffic simulation

“…where l i is the length of link i, n is the number of links (Williams et al 1987;Csikós, Tettamanti, and Varga 2015). The second approach interprets the MFD of one single road link of the network, i.e.…”

“…The idea of urban MFD has been generally researched in the previous decades, e.g. Mahmassani, Williams, and Herman (1987), Daganzo (2007), Keyvan-Ekbatani, Papageorgiou, and Papamichail (2014), Csikós, Tettamanti, and Varga (2015), He, He, and Guan (2014), Geroliminis and Daganzo (2008). Furthermore, Guan and Shuyan (2008) found that the three-phase traffic theory and fundamental diagram are not conflicting when it comes to the urban area.…”

“…ahol l i az i-edik hálózati útszakasz hossza, n pedig az útszakaszok száma [5], [6]. A kifejlesztett szoftveres környezet célja az is, hogy a most kiépülő zalaegerszegi autonóm tesztpályán [14] közvetlenül alkalmazható legyen.…”

Pattern Recognition Based Speed Forecasting Methodology for Urban Traffic Network

“…The importance of relevant average speed forecast is straightforward for ITS applications, e.g. (Csikós et al 2015a;Ficzere et al 2014). At the same time, it must be emphasised that resources' sharing based services also require information sharing.…”
