Vehicle - fix costs: strongly dependent on specific application |
| |
|
|
|
|
An advanced traffic optimisation system would require some additional information and communication on-board equipment, such as GPS units, GSM-R transmitters and a software to display driving recommendation on the drivers' desk. Some of this equipment may already be deployed for other purposes in many fleets. Therefore the vehicle fix costs heavily depend on the technological point of departure. |

|
Infrastructure - fix costs: strongly dependent on specific application |
| |
|
|
|
|
Just as in the case of vehicle fix costs the required
infrastructure investment strongly depends on the point of departure in a given
infrastructure. |
|
|
|
|
| |
|
|
|
Infrastructure - running costs: unchanged |
| |
|
|
|
|
- There could be slightly increased running costs due to a more complex
train control system. However, there could be reduced personnel costs due to
automation in train control.
- On the other, improved capacity and slot management could increase
the revenues of the infrastructure manager.

Amortisation: (no data) |

The amortisation time of an advanced traffic management system strongly
depends on the intial investment, cf. vehicle - fix costs and infrastructure
- fix costs. |

Advanced centralised traffic management systems are seen as one of the most effective instruments for raising traffic fluidity. They will improve two of the most critical quantities in today's railway operation: overall punctuality and infrastructure capacity. A very considerable increase in energy efficiency is a very important side effect. Barriers for such a system are high, since a fleet-wide roll-out of additional IT components is necessary and an integration into existing train control hierarchies is to be achieved. Given the immense benefits for service quality, infrastructure management and energy efficiency, the introduction of advanced traffic management systems will be a key success factor for the efficiency and quality of railway operation in dense infrastructures. The cost effectiveness and speed of the introduction of traffic optimisation systems strongly depends on standardised interfaces ensuring maximum synergy effects with other telematic solutions. |
