Warsaw Trams implement priority for their vehicles on Towarowa and Okopowa streets in Wola and Grochowska streets in Praga Południe. The changes will be introduced by the end of the year at 12 intersections. As tram drivers argue, the system benefits passengers (time) and the company (money).

The system, which allows trams to pass through junctions with priority, will appear on new sections of six kilometers. The City Hall has just signed a contract to launch it on two routes.

“The first is the line of Towarowa and Okopowa streets between Zawiszy Square, Kercelak and Babka roundabout. In order for vehicles to go faster on this almost 3.5 km section, changes will be introduced in 12 places with traffic lights. The second new route with a green wave is Grochowska street between the Wiatraczna roundabout and the Gocławek terminus. Here, the green light will appear at six intersections. Thanks to this, the trams of line No. 9 along their entire route will be able to accelerate up to 10 minutes in total “- said the town hall.

Work related to the implementation of the priorities in Wola and Grochów will last until the end of the year and will cost PLN 576 thousand net. The contractor is Siemens Mobilty.

In Okopowa and Towarowa, trams will be given priority at the intersections with Kolejowa, Grzybowska, Chłodna, Leszno, Żytnia, Wolność, Niska, Stawki and Powązkowska streets. Traffic at the Daszyńskiego roundabout will also be coordinated. On Grochowska, the green wave for trams will operate at the intersections with Wspólna Droga, Zamieniecka, Żółkiewskiego, Headquarters, and Wiatraczna, and in the eastern part of the Wiatraczna roundabout.

GPS technology and cloud

At the moment, the green wave for trams is already operating at 160 out of 255 intersections with tracks (63 percent). Ultimately, the system will operate at all intersections with traffic lights through which trains pass. By the end of this year, the green wave for trams is expected to appear in 75 percent of such places, and by the end of 2022 it will cover a minimum of 90 percent of intersections.

Warsaw’s tram drivers use solutions based on GPS and cloud computing. Rather than installing sensors to detect stockpiles, building underground utilities and sometimes digging up streets, installation work is limited to the intersection itself. As they calculate, in this way the city can save even several hundred thousand zlotys at one intersection.

“We have been implementing the priorities for trams since 2014, and the effects are visible throughout the city. Line 17 from Tarchomin now reaches Służewiec ten minutes faster, and line 41 from Żerań Wschodni – by nine minutes. The journey via Bródno to the Vilnius Railway Station in Praga has been shortened by three minutes, and the speed increased by 15% The very popular line 2 from Nowodwory to the Młociny metro station runs in less than five minutes, which means the travel time is shortened by as much as a quarter and with a communication speed of approx. 30 km / h, it is one of the fastest tram lines in Poland “- tram drivers boast. And they calculate that thanks to such solutions it was possible to “regain” 29 trams and 90 jobs to operate them.

Lower energy costs

The green wave also lowers energy costs. An example is to be Marymoncka Street. “When the priority for trams was switched on, the energy consumption in this section fell by 13 percent. The company saves about PLN 70,000 a year on only one tram line” – the capital city hall said.
