The physics of traffic and regional development

Helbing, Dirk ; Nagel, Kai (2004)

This contribution summarizes and explains various principles from physics which are used for the simulation of traffic flows in large street networks, the modelling of destination, transport mode, and route choice, or the simulation of urban growth and regional development. The methods stem from many-particle physics, from kinetic gas theory, or fluid dynamics. They involve energy and entropy c...

Incorporating within link dynamics in an agent-based computationally faster and scalable queue model

Agarwal, Amit ; Lämmel, Gregor ; Nagel, Kai (2017)

The growing pace of urbanization increases the need of simulation models to handle large-scale scenarios in reasonable time. The present study proposes a fast spatial queue model, which is anchored to an agent-based travel demand simulation framework. The existing queue model is extended to produce more realistic flow dynamics by introducing backward travelling holes to mixed traffic conditions...

Mind the price gap: How optimal emission pricing relates to the EU CO2 reduction targets

Kickhöfer, Benjamin ; Agarwal, Amit ; Nagel, Kai (2018)

From the transport economic literature, it is known that optimal pricing of (environmental) externalities improves the urban system. In contrast to theory-based optimal pricing strategies, real-world policy setting often follows so-called “backcasting” approaches where certain targets are set, and policy measures are implemented in order to reach those targets. An example for the latter approac...

Buhrke, David ; Tavraz, Neslihan N. ; Shcherbakova, Daria M. ; Sauthof, Luisa ; Moldenhauer, Marcus ; Vélazquez Escobar, Francisco ; Verkhusha, Vladislav V. ; Hildebrandt, Peter ; Friedrich, Thomas (2019-02-12)

Phytochromes are red/far-red light sensing photoreceptors employing linear tetrapyrroles as chromophores, which are covalently bound to a cysteine (Cys) residue in the chromophore-binding domain (CBD, composed of a PAS and a GAF domain). Recently, near-infrared (NIR) fluorescent proteins (FPs) engineered from bacterial phytochromes binding biliverdin IXα (BV), such as the iRFP series, have beco...

Estimating Pore Water Electrical Conductivity of Sandy Soil from Time Domain Reflectometry Records Using a Time-Varying Dynamic Linear Model

Aljoumani, Basem ; Sanchez-Espigares, Jose A. ; Wessolek, Gerd (2018-12-13)

Despite the importance of computing soil pore water electrical conductivity (σp) from soil bulk electrical conductivity (σb) in ecological and hydrological applications, a good method of doing so remains elusive. The Hilhorst concept offers a theoretical model describing a linear relationship between σb, and relative dielectric permittivity (εb) in moist soil. The reciprocal of pore water elect...

German public utilities

Stiel, Caroline (2018)

Since 1998, public firms have had to adapt to a market environment that is very different from the post-war era in Europe. The liberalisation of services of general economic interest across Europe led to competition between public and private providers, while new technologies require infrastructure investment and innovative solutions. In addition, urbanisation and population ageing pose new cha...
