City of Belgrade signed a contract with the Serbian companies Yunex Traffic and Telegroup at the end of 2019 for the implementation of the adaptive management system by traffic, that is, smart traffic lights, at 322 intersections. It is known that by 2022, 280 intersections will have received smart traffic lights, this information was published in a promotional text, and after that there was no more news about it.
Drivers know about smart traffic lights in Belgrade, but claim that either they were never installed, or they never worked. In any case, they do not feel that the traffic congestion has decreased since they were reported.
Who did the measurement?
What are smart traffic lights? This is when traffic is managed in real time from one center. For example, when there is a match, the system recognizes that there is a traffic jam around the stadium, so it regulates it. Or when it's morning rush hour. Or whenever needed.
Three years ago, in the aforementioned promo text, it is written that a comparison was made before and after the introduction of smart traffic lights, and that the results show that the travel time and the number of stops during the morning rush hour on Bulevar Kralja Aleksandra, in the direction from Cvetkova pijaca to Tašmajdanski Park, were reduced by 26%. It was also calculated that the journey from the Faculty of Law to Trg Slavija was reduced by 5%.
It does not say who made these measurements.
But it says that the Secretariat for Transport made a decision to give priority to trams in order to promote public city transport and reduce pollution caused by traffic. This decision, the Secretariat for Transport announced in that text, was implemented in Rooseveltova, Kralja Aleksandar Boulevard, Milutin Milankovića Boulevard, and Jurija Gagarina Street. Thanks to this, the journey from the first to the last stop was shortened by 40 percent.
They are waiting for the green light for the tram
The Belgrade on the Move organization says that this is not true, they claim that trams still wait at traffic lights as long as all other vehicles, and that they do not have priority. That is why they call on the City to, instead of planning new tenders for the purchase of trams, modernize traffic by introducing smart intersections.
"A tram that stops at a red light is not an acceptable means of transport for citizens or for city traffic," says Nikola Radin, executive director of the organization Belgrade on the Move.
He also says that "it's not just a traffic story. It's a matter of attitude towards people. Because every tram that arrives on time means hundreds of people who arrived at their destination without nervousness, without running, without apologizing for being late. And that's not a luxury. It's the basis of a civilized life. Something that isn't measured by numbers from statistics, but I feel that the city you live in counts on you and counts on you."
He points out that there is not a single publicly available analysis of smart traffic lights by an authoritative institution, primarily the Faculty of Traffic. "We only know about smart traffic lights based on the announcement of the Secretariat for Traffic," says Radin.
He also notes that the price of all that is not known.
Our intelligence in Europe
He reminds that the product Yunex Traffic, produced in cooperation with Siemens, "already works in Helsinki, Krakow, Ljubljana and Maribor? It is installed in the systems of those cities, saves time, fuel, nerves. It works. And it is exported. Serbian wisdom. Only Belgrade does not know what to do with it".
In Europe, this type of traffic regulation has been applied for a long time.
For example, says Nikola Radin, "in Krakow, where the winter is severe and where people do not see transport as a social category but as a right, trams have priority at every major intersection. And in Ljubljana and Maribor, which are smaller cities but with greater respect for common sense, public transport vehicles pass where Belgrade is still waiting for the green light".
"In Belgrade, for now, they still count on you to wait silently at the red light. In the tram. In life. But maybe it's time to change the color of the light. If we already have a mind, let's leave it here. Not everything has to be exported. Not everything has to be waiting," says Nikola Radin.
