Toll charges reduce travel time

25.09.2007
A smart introduction of a variable toll charge, with different rates at different departure times, reduces traffic jams. Even small toll charges can exert a large effect on the total travel time, concludes Dutch researcher Dusica Joksimovic.

oksimovic developed a simulation model that can help policy makers to estimate the consequences of various toll charges. The model predicts, where, when and how much toll must be charged for the desired policy outcomes, such as reducing the total travel time of all travellers or maximising the toll incomes (revenues).

Based on a toll value entered, the model iteratively calculates the impacts on road congestion and the total toll incomes and searches for an optimal composition of the toll charge.

The model contains a number of variables. For example, it takes into account the different characteristics of travellers. People who want to be at a preferred destination by a given time are more inclined to pay more during rush hours than people who want to travel as cheaply as possible and are flexible with respect to their arrival time. A flexible toll charging system in which car drivers must pay more at peak times than off-peak times leads to less traffic jams, but also maximum toll incomes.

Various factors play a role in the problem of toll charges: the government wants to minimise both the total travel time of all travellers and harmful environmental effects whilst at the same time maximising toll incomes to pay, for example, for roadworks. Individual motorists mainly want to make their journeys as quick and cheap as possible. These considerations lead to a complex decision model in which the various variables are dependent on each other. The instrument that Joksimovic developed during her doctoral research can provide policy makers with a quicker insight into the outcomes of policy measures.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
