PREVIOUS MODEL WORK
PREVIOUS MODEL WORK The following BRU reports form the main input for this updated model work Utrecht_dynamic_modelling_phase 1_report, February 2013 Utrecht_dynamic_modelling_phase 2_part A_B_v1, November 2013 Utrecht_dynamic_modelling_phase 2_part C 2020_v1, November 2013 They are referred to in this report as Prior Ops study
MODIFICATIONS OF BASE DATA COMPARED TO PRIOR OPS STUDY Alignment of Uithof lijn Modifications on SUNIJ-Lijn Speed profile considering modifications agreed in Project Step 1 Uithof lijn (no modifications) SUNIJ lijn (significant modifications on Ijsselstein branch and section Nieuwegein Stadscentrum Utrecht Centraal)
SPECIAL REQUIREMENTS TAKEN OVER FROM PREVIOUS MODEL Regulation at Utrecht OVT to assure needed punctuality Influence of bus traffic at Utrecht OVT Critical: Turnaround in Utrecht OVT to permit short shuttle between Uithof and Utrecht Turn around time: OVT minimum 175 s plus 85 s for passenger exchange P+R De Uithof max. 300 s Prior track layout
TURNAROUND TIMES Turnaround time: Technical minimum turnaround time: Technical minimum turnaround Dwell time for boarding and alighting Buffer time Minimum planned turnaround time Vehicle shut down: Driver changing cab: Vehicle ramp up: Total: 20 sec about 2 min 20 s 3 min 4 min minimum turnaround time including Sum of turnaround times at both ends of line shall be between 10% and 20% of overall runtime Dwell time for boarding and alighting Distribution depending on traffic demand and platform access Can be allowed while driver is changing the cab (at least in case of delay) Additional buffer time Remaining time to start at planned departure time
DUTY ROASTER EFFICIENCY Efficiency Definition: Runtime / (Runtimes + turnaround times) Shall ideally be between 80% and 90% 80 % or lower In case the value is below 80 % the (non-productive) turn-around time is compared to the (productive) run time too high The number of vehicles will increase leading to finally higher investment and higher operational cost The system robustness on the other hand is high as delays can be quickly re-covered 90 % or higher In case the value is 90 % or higher the (non-productive) turn-around time is compared to the (productive) run time too low The system robustness drops as delays cannot be re-covered anymore On the other hand the number of vehicles will decrease leading to lower investment and eventually lower operational cost But the system is not reliable anymore and the attractiveness for passengers goes down

VEHICLES
VEHICLE PARAMETERISATION AS IN PRIOR OPS STUDY 32 m single unit 42-43 m single unit combined to a 75 m double unit
NEW CAF VEHICLE PARAMETERISATION Traction effort curve: Acceleration Traction effort EL 4 (4 standees per m 2 ) identical with curve EL 6.67 Acceleration limited for comfort reasons to 1,2 m/s 2 (Force) 33 m single unit 42-43 m single unit
NEW CAF VEHICLE PARAMETERISATION Can be coupled to a double unit (simulated as one vehicle train)
SHORT AND LONG VEHICLES The CAF vehicles tested are 33 m long vehicles. In the case extended vehicle would be used, they would need one motorised bogie more. From experience the performance would be in this case the same as for the short vehicle.
RUN TIMES
OPERATIONAL KEY NUMBERS: CALIBRATION RUNTIME Comparison of runtimes based on vehicle and infrastructure from Prior Ops Study New OpenTrack model: New model with similar runtimes compared with Prior Ops Study 2014 with the same vehicles assumed
SPEED COMPARISON Maximum speed adapted in the model Simulation results: No significant change of runtime
VEHICLE EFFECTS ON RUNTIME Comparison of undisturbed runtimes (to compare vehicle influence): Single line one-directional simulation Remark: Run times without operational effects are shorter than system runtimes CAF vehicle shows shorter runtimes than prior reference vehicle of about 1 min between P&R De Uithof and Ijsselstein and Nieuwegein respectively From To Reference vehicle CAF vehicle Difference P+R De Uithof Ijsselstein Zuid 00:52:45 00:51:32 00:01:13 Ijsselstein Zuid P+R De Uithof 00:54:07 00:53:05 00:01:03 From To Reference vehicle CAF vehicle Difference P+R De Uithof Nieuwegein Zuid 00:47:17 00:45:55 00:01:22 Nieuwegein Zuid P+R De Uithof 00:47:22 00:46:17 00:01:05

OVT PLATFORM OCCUPANCY Tracks 1 & 2 respectively 3 & 4 use the same platform between the two tracks. From the safety point of view considering the amount of passengers at one point of time on a platform there boarding and alighting at the same time shall be avoided. Scenario C1: Tracks 1 & 2: No occupancy at the same time OVT Platform occupancy Arrival at track 3 just after departure at track 4 Scenario C2: Arrival and departure at track 2 while track 1 is not used Arrival and departure at track 3 while track 4 is not used

RISK ANALYSIS SCENARIO C2 Ramboll/MMD have calculated 54 vehicles without reserve for the scenario C2 With sufficient turnaround times a reliable operation can be assured. This implies the avoiding the change of line (Ijsselstein/Nieuwegein) at the turnaround in P+R De Uithof A further optimisation would not be recommended regarding the risk of longer dwell times as a result of different door opening and closing times of the CAF vehicles. Precondition for this operational concept would be: Using a short turnaround at OVT and The change of line at P+R De Uithof for the intermediate short line service P+R OVT (combination of Nieuwegein and Ijsselstein line).

RISK ANALYSIS SCENARIO C1 So far Regiotram calculated with 27 for the Uithof start operation and then 26 options on top of this, in total 53, 26 vehicles are today operating on the SUNIJ-line. But this takes not the efficiency gains of the combined operation into account. Ramboll/MMD have calculated 42 vehicles for this without reserve Short turn-around times at P+R and OVT High efficiency There is a risk is that due to higher stop times (the doors at the SIG trams are now opening at a speed below 3 km/h, the new CAF trams will have to go down to 0 km/h) the gain in run times can be lost again. In this case a reliable operation can be assured by using 2 more vehicles and longer turn-around times.
CONCLUSION
CONCLUSION New OpenTrack model: New model infrastructure built-up Model results of Prior Ops Study confirmed Runtime of CAF vehicles in preliminary model runs slightly shorter than reference vehicle from Prior Ops Study Effect of runtime on key number of scenario C2 with 12 / 6 / 3 min headway (shorter runtime, longer turnaround) Concept of scenario C1 with 15 / 7,5 / 3-4 min headway implemented Modification of speed profile does not affect the runtime significantly Model ready to use for further analysis and new scenarios
