D8.3 Developed simulation methods and models for capacity evaluation of ETCS and C-DAS/ATO

The aim of EU Rail Flagship Project 1, Deliverable 8.3 is to develop simulation methods and models for capacity evaluation of ETCS and C-DAS / ATO. We also include the enhanced TMS-functionality and Next Generation Brakes as DATO (digital and automatic train operation) techniques to be researched. This report describes the developed simulation methods as well as accompanying planned simulation scenarios. For the latter, numerical results and analysis will follow in deliverable 9.2 of the follow-up work package 9.

The report uses the following structure. First, it presents general information on railway traffic simulations to contextualize our simulation method choices later on. Next, the report describes different current simulation tools, all of which will be used to study at least one of the different DATO techniques and scenarios. In total, this report describes 8 simulation packages.
Next, the report describes the developed simulation methods for each DATO-technique. Specifically, for each DATO-technique, the report offers a short description of the technique, an explanation of the developed simulation methods, an outline of how the previously described software packages (may) implement these methods, and a validation of the simulation methods to technical readiness level 4.
The basis for all other methods is ETCS level 2, the signalling system that will replace the current class B systems in the near or further future. Thereafter follows Hybrid Train Detection (formerly HL3), where the report presents a method for simulating the virtual subsections and train integrity monitoring. For NG-Brake, the method consists of altering traction and braking parameter settings compared to the basic ETCS settings. For C-DAS and ATO, the method relies on the implementation of altered driving strategies. The method for TMS includes either an adapted parameter setting for emulation or the configuration of a TMS for a proper simulation of the effect.

Finally, the report describes the scenarios that will be simulated with the developed methods with a brief overview of infrastructure, timetable and rolling stock. In total, the report describes 17 geographical areas across Europe. Each will be used to simulate one or multiple DATO-techniques, using complementary software packages. The methods, scenarios and results are related to several other work packages in FP1-MOTIONAL and FP2-R2DATO.

In sum, this report gathers and presents information about simulation, methods for simulating DATO-techniques, verification of the methods, and scenarios to be calculated. The information gives the possibility of a broad evaluation of methods and results. The follow-up work package 9, deliverable 9.2, will present outcomes of the simulations.
