| Abstract: | In the planning phase of a project, traffic network designers have a lot of choices to make when designing junctions in urban networks. The traffic network designers base the design choices, among others, on design guidelines for junctions. These design guidelines contain a set of rules based on rules of thumb and decision diagrams. The main criteria for these rules and decision diagrams are traffic flow and safety. A check is usually performed for costs and local criteria while guidelines for emissions, noise and fuel consumption barely exist (Bezembinder, 2013; CROW, 2012). However, the environment is becoming a more important subject nowadays. And policies are more and more based on minimizing the five most important (negative) external effects of traffic: congestion, traffic safety, global warming, air pollution and noise pollution. Research of Bezembinder is aimed to develop new junction design rules for urban traffic networks in the Netherlands, reckoning with those policy objectives. The research described in this document aims to contribute to the research of Bezembinder by developing an emission modelling approach which can determine emissions values of isolated junctions. In the research of Bezembinder a junction model is used that produces macroscopic static flow data. An emission model that is able to use these data should be connected to the junction model to calculate emission values of different junction designs. With the results the junction designs should be compared to each other. Furthermore, the approach should not be calculation capacity and calculation time consuming because it has to be used in a network situation. Therefore, the objective of this research is: The objective of this research is to develop a static macroscopic junction emission model which produces results that can be used to compare different junction designs on policy relevant emission substances. |
