7 Turnback arrangement Arrangement at the terminus of line 2 in the city centre > Terminus at Matkakeskus next to the railway main station > 1 track stub to turn back after Matkakeskus station MATKAKESKUS Line 1 MATKAKESKUS Line 2 7

8 Speed limits in OpenTrack model Speed reduction at curves > Radius determines the speed reduction > Reduction according to the German BOStrab reglementation > Input of rounded values in the model Speed reduction due to the alignment > 30 km/h across the city centre (around the market place) > 40 km/h in track sharing car/tram area > 50 km/h along tram tracks on the side of the street (in a residential area) > 60 km/h along tram tracks on the middle of the Street (in a residential area) > 70 km/h outside residential areas 8

13 Conflicts among the line Track and stop sharing with bus > 5 track sharing segments with bus > 15 stop sharing with bus > Runosmäki branch: Ruohonpää, Kähäri, Raunistulan koulu and Puutori > Varissuo branch: Tuomiokirkko, Yliopisto, Sairalaa, Kupitaan kampus, Koukkarinkatu and Pelttarinkatu > Skanssi branch: Vasaramäki, Kauppakeskus, Koulu and Piispanristi > Trams have to stop longer depending on the number of departures per hour and possible bus interference Stop time distribution for buses 13

14 Conflict among the line Track sharing with car > 6 track sharing sections with car > Reduction of running speed of the trams according to the traffic > Trams can run from 60 % to 90 % slower in the model Priority at junctions > 5 junctions with minor priority (average stop time 15s) > Tampereentie > Eerikinkatu > Uudenmaankatu > Hämeenkatu > Tykistokatu > 100 % priority for the other ones Stop time distribution at junctions 14

23 Simulated scenario with OpenTrack Simulation of peak hours > Operation on a week day (6:00 AM to 12:00 AM) > Six hours simulation in OpenTrack > Departure each 7,5 for both lines Simulated lines > Line 1 from Runosmäki to Varissuo > Line 2 from Matkakeskus to Skanssi The results from the OpenTrack simulations are deducted from the time period where the travel times are the highest. This time period sets the size of the rolling stock needed in order to operate the network. However the travel times outside peak-hour are a little shorter. 23

24 Simulated scenario with OpenTrack Six different simulations with OpenTrack > Scenario A: Basic simulation with dwell time distributions (no conflict) > Scenario A.1: Basic simulation with track sharing with car > Scenario A.2: Basic simulation with track and stop sharing with bus > Scenario A.3: Basic simulation with minor priority at the junctions > Scenario B: Simulation with the three conflicts types > Scenario C: Simulation from the worst case scenario * The next slides show the final results (scenario B). 24

25 Scenario B Final results Travel time for each line Line 1 Runosmäki to Varissuo Turnaround time Varissuo to Runosmäki Turnaround time > Turnaround time = 13 % Travel time Line 2 Matkakeskus to Skanssi Turnaround time Skanssi to Matkakeskus Turnaround time > Turnaround time = 38 % Travel time 25

Higher delays in the city center!

39 Scenario C : Worst case scenario Rolling stock Line 1 > 14 trams > ~ 16 with 10% reserve Line 2 > 7 trams > ~ 8 with 10% reserve Line 1 Line 2 Line 1&2 Reserve Total Estimate with OT % > 23 vehicle needed in the worst case scenario seem the minimum rolling stock needed: 21 x 10% = 2,1 could be rounded to 2 vehicles for the reserve! 39

40 Has the wish for a regular 3-4 minutes headway on common track section any impact on rolling stock? Consequences of 3-4 minutes headway : > Line 2 has to fit to line 1 headway. > The minimum turnaround time of 4 minutes on line 2 imposes a specific travel scenario. > The headway has however no impact on rolling stock. Tram 1 Tram 2 Tram 1 Tram 2 40

41 How to spare some vehicles? Other headway? > Lower demand on line 2 allows a larger headway Higher demand Needed Tram Headway during peak hours capacity per hour in minutes Line Line theoritical seats 65% real seats 150 real seats > Reduction of rolling stock depending on the headway on line 2: > 7,5 ph = 7 trams to operate > 10 ph = 6 trams to operate (-1 vehicle) > 15 ph = 4 trams to operate (-3 vehicles) > 20 ph = 3 trams to operate (-4 vehicles) > No more regular headway on the common part between Tuomiokirkko and Matkakeskus! Lindforsinkatu TTK GmbH

42 How to spare some vehicles? Other line concept? > Line 1 from Runosmäki to Skanssi (37 travel time) > Line 2 from Matkakeskus to Varissuo (26 travel time) > Same rolling stock needed! > First concept feets the demande better Concept with line 1 only (-8 vehicles = 7 trams + 1 reserve)? > 16 trams for line 1 only ( reserve) > Demand forecast for line 2 very low for a tram or even a BRT system!
