Dynamic Toll for Smooth-Flowing Traffic

15.08.2011
Highway traffic can flow more freely thanks to a dynamic toll. Siemens has developed a special algorithm for traffic control systems that adjusts the toll charge to the current traffic situation.

In return, the system lets motorists enjoy the benefits of getting to their destinations more quickly, while also helping to prevent traffic jams and reduce fuel consumption and CO2 emissions. The first special highway lane with the innovative control system, known as the “fast lane”, is on the highway connecting Jerusalem and Tel Aviv in Israel.


Many densely populated areas have problems with traffic during peak periods. Special lanes whose use is subject to a fee are often provided to improve the flow of traffic and encourage people to form car pools or use public transportation. The greatest challenge here is the need to set the fees at a level that will ensure the lane’s capacity is sufficiently utilized and that traffic jams will be prevented. Siemens Mobility has responded to this challenge by developing a traffic control system that enables a steady driving speed while ensuring optimal use of capacity.

The system uses induction loops in the road surface to register the speed and numbers of vehicles on the free driving lanes and the fast lane. The heart of the system is a complex algorithm that uses the measured data to calculate the toll fees down to the minute. Ultimately this leads to evenly distributed traffic density on the special lane: When traffic is light, the toll fee drops, giving drivers an incentive to use the lane. When traffic gets heavier, the fee increases, which deters some drivers and thus prevents congestion. The updated toll fee is displayed on electronic traffic signs at entrances to the fast lane. For calculating the toll fee, a video system films the vehicle’s license plate number when it enters the lane. The fee can be debited from the bank accounts of drivers who have registered for this option in advance; otherwise they receive a bill. Buses and fully occupied vehicles are exempt from the toll. The fast lane is 12 kilometers long and makes it possible to cover the distance in about 12 minutes — compared to the 30 to 60 minutes the trip can take during peak hours.

The fast lane was built by Shapir Civil & Marine Engineering Ltd., an Israeli company. And another Israeli company, R.S. Industries / Orad Group, is responsible for toll billing. From Siemens’ point of view, a very promising market for the new traffic control system is the U.S., where there are already many fast lanes in use, but so far with little flexibility of toll calculation.

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...
