Tram in Turin – synchronized traffic lights!

Tram in Turin

What is the city of Turin doing to help Tram in Turin?

GTT, together with the City of Turin, completed a series of measures to make the Turin tram network more efficient. The system has seven lines which, along with the underground, constitute the backbone of the city transport network due to the importance of connections, the number of passengers transported, and eco-sustainability.

Traffic light priority, multiple reserved lanes, fewer stops: these are the three coordinated actions that will make the tram route more fluid in city traffic and allow customers to reach their destination faster.

Traffic light priority

Since last year, the traffic light priority has already made it possible to speed up the distances of most tram lines. Line 15, for example, has reduced travel times by 7% in the morning rush hour and by 6% in the remaining time slots; it is about 8-9 minutes saved by the terminus at the end of the round trip. Line 16 has reduced travel time in the morning and on average by 4% in the afternoon (which translates into 2 minutes less in the morning and 3 minutes less in the afternoon). The project will end in October 2020 and will allow a further reduction in travel times on the entire tram network by around 3%.

Reserved lanes

GTT is completing the extension of the preferential pathways that involve Corso Belgio for line 15 and Via Cibrario for line 13. With these further measures, line 13 increases the reserved lanes from 40% to 55% and line 15 from 50% at 66%. The final goal, in October 2020, is to reach an average of 90% of preferential or courtesy lanes on the entire tram network, with a reduction in travel times of 2.5% (note that already lines 3, 4, 9, 10 are almost entirely on reserved lanes).

Tram in Turin Stops

The project foresees that, from next December 1st, the tramways will also have fewer stops along their route; 30 out of the 453 total stops of the entire tram network. The 30 stops were chosen based on the following criteria: distance from the previous and next stop (in some cases just over 100 meters), distance from the poles of interest or interchange, number of daily validations.
Even with the new interventions, the stops on average are not more than 500 meters apart; this means that to reach a chosen stop, a user travels for a maximum of 250 meters.
The comparison and the dialogue with the Circumscriptions have allowed also doing some tricks to the project that initially envisaged the suppression of 41 stops, then reduced to 30.

The optimization of the stops will lead to a further reduction in travel times of 3%.
The entire project, coordinated with the three priority traffic light actions, reserved lanes, and optimization of the stops, aims to achieve an average reduction in travel times of 8.5% on all tram lines. With the same resources used, this will result in an increase in the potential supply of 190,000 km/year and over 30 million seats * km/year, equivalent numbers to 4 tram locomotives used at peak hours, and eight driving agents on the day school type of work.

From Thursday, 21 November, passengers will receive information about the measures in progress: the communication will be conveyed at the stops, onboard the vehicles, and on all communication channels to GTT customers offline and online.
