the Gray boxes bring traffic, the city of Zurich to the roles. Unremarkable they stand at every traffic light intersection. Sober also their Interior: not much more than a fuse box in the private household. “Nothing here looks like a high-tech, but there’s more to it,” says Joos Bernhard, head of traffic management of the city of Zurich. “The System is working properly.”
in 1971, took Zurich a leading role. It was the world’s first city that sat in the passenger traffic on a computer control. Even today, the interest. Recently, a Delegation from Norway visited the Department for transport to the mill alley, the Zurich transport system, says Bernhard.
But a part of the infrastructure is outdated and needs to be replaced. Next September, the Department for transport, replaces the first control device in six years, all 400 will be replaced.
exchange
The System is complex, even small changes: As in last October, the 31-Bus to the Klusplatz left turned off, it came to traffic delays. For a month the employees were. “It was like a Gordian knot,” says Bernhard. The solution: Although in Zurich, the public transport is prioritized, had to wait for the Trams for a few seconds. The journey will take a bit longer, it comes to less traffic. “Safety first,” says Joos Bernhard.
The control center at the mill lane monitors the flow of traffic.
The Department for transport does not want to stay. Zurich exchanges with other cities such as Frankfurt or Stuttgart. “In Germany the cities are in some areas more than we do, and pursue other approaches, especially because the automotive industry makes printing,” says Bernhard. Zurich shall also examine these approaches, with particular benefit to the motorists of the day, does not want to accept but easy. It is necessary to estimate which amount of sense, as new technologies come on the market. And not all were for the Zurich-based System, with its strong public TRANSPORT prioritization in a profitable way, says Bernhard.
the development comes a Few in Zurich to slow: The green liberals see great development potential for intelligent solutions in road traffic. In the summer of 2017, and requested the city Council to consider a two-way traffic regime on the bellerivestrasse. This should be reduced in favour of a Velowegs on three tracks, the middle track is, depending on the volume of traffic in the Morning heading towards the town centre in the evening out of town. Civil engineering head Richard Wolff (AL) would like to examine this variation, he said at the end of last year.
Flexible track mark
In the meantime, the GLP has the group already been a further advance in Parliament, submitted. It calls for the “digital Transformation” of the traffic steering. “It would be stupid to use the new technical possibilities,” says GLP-municipal Council Sven Sobernheim, of the traffic studied systems. “In Höngg, the houses are close to each other. For more than two tracks, it rarely has space,” he says. So the control needs to be optimized. You should also make use of existing data.
Modern information systems for vehicles can communicate with other cars and with a traffic control system. So it would be eventually possible to know of all the cars, where they are located and in which direction you are driving. “The more data we can feed into the Computer, the more efficient the System reacts,” says Sobernheim. He is thinking about it to replace the drawn markings on the ground through the flexible Display. In the evening the traffic lanes could be converted easily, so that more cars can leave the city at the same time.
To Express the specific proposals of the GLP Joos Bernhard, Department for transport, because the Motion is still pending. He confirmed, however, that a wireless System for the communication between vehicles and the light signals would be possible.
hackers, and privacy
However, wired systems such as those in the Asphalt-embedded detectors that detect the presence of a car in front of the traffic lights, have advantages: “The cables are protected in the pipe safe from hackers.” Also the privacy issues are smaller.
The infrastructure, which renewed the city in the next six years, will continue to work with copper cables. But it would be technically possible to use wireless data to the System. The city is open to this possibility.
