Brief description: With an average daily traffic volume of almost 50,000 vehicles and up to five public transport lines running in parallel every ten minutes, the north-south link is one of the most important arterial roads in the center of the city of Dresden. Together with the Dresdner Verkehrsbetriebe, the city of Dresden and several industrial partners, the 4.2-kilometer-long route was upgraded with a quality-based traffic control system (QLSA) and the cooperative driver information system COSEL was introduced at DVB AG for operation- and energy-optimized driving.
Since the QLSA control system takes into account the needs of different modes of transport and, in particular, the operational and passenger-relevant quality criteria of public transport, significant improvements in overall traffic quality have been achieved. In addition to stabilizing the timetable situation, QLSA also achieved a fundamental reduction in travel times on the north-south connection. As a result, in August 2015, DVB AG reduced the scheduled transport times for Lines 3 and 7 by three minutes and for Line 8 by one minute per round trip.
With the COSEL driver information system, the driving personnel were provided for the first time in the world with a system in streetcar operation that avoids unnecessary braking and acceleration processes at traffic lights by means of stop and travel recommendations. As a result, savings in traction energy consumption of up to 30% have been demonstrated.
