MODELING SIMULATION AND OPTIMIZATION OF INVESTMENTS

SARDINIA (ITALY)

The objective of the simulation of the Sardinian railway network consisted in the targeted selection of the best scenario of intervention for the infrastructural and technological upgrading necessary to define an operations model enabling the combination of high-speed regular services between the Northern and the Southern part of the island with regional short-haul services. The main issue of such case study was represented by the fact that most of the considered railway network is constituted by single-track lines and is featured by winding planometric and altimetric characteristics.
Lift adopted the microsimulation to identify the essential upgrading interventions addressing the creation of a specific operations model which could successfully serve the whole railway transport system at hand.

Our tasks:
- Microscopic modelling of the entire regional railway network according to different scenarios, not only related to various infrastructural and upgrading interventions, but also in terms of diverse train timetables
- Comparison among developed scenarios
- Stochastic simulation
- Optimization of investments
