Lift. Outstanding experience in simulation.

In railway engineering, Lift activities are focused on operations (a central issue in railway transport planning and design) which are the result of a complex interaction among infrastructural features, signalling, rolling stock and timetable. This interaction is further complicated by a number of human factors, other unpredictable phenomena and stochastic disturbances.

In particular Lift performs:

  • Railway operations analysis (from an aggregated to a more detailed level)
  • Operations modelling and simulation

SUPPORT FOR PLANING EFFECTIVE INVESTMENTS

Infrastructure Planning:
Long- and short-term definition and assessment of Infrastructure improvement measures.

The required objectives in terms of capacity and travel times can be reached through several combinations of infrastructure and signaling design (investments), services (timetable) and rolling stock.

Long-term large investments may be realized using a step-by-step approach, solving bottlenecks and avoiding un useful expenses.

This approach allows to both gain benefits also in short and medium term and to minimize the risks related to traffic forecasts.

A well-designed network allows forecasted traffic to flow with minimum perturbation, avoiding unnecessary construction in order to minimize costs.

Lift supports planners with the highest involvement at different design scales: from the long-term functional design of large projects to gradual improvement plans to increase capacity and small, punctual interventions that allow operating a higher number of services.

When an existing line or network needs to be improved, Lift suggests, defines the requirements and tests the interventions, comparing the performances of multiple scenarios to operate the forecasted number of services. The methods specifically developed at Lift consider the trade-off between capacity and service reliability in long-term planning, so as to estimate requirements with high precision. The result is a very effective investment.

TIMETABLE PLANNING

AT THE HEART OF RAILWAY OPERATIONS, WITH THE MOST ADVANCED METHODS AND TOOLS

We define drafts and compare scenarios using internationally-awarded stochastic models.

The timetable is the core of railway operations. It best exploits the infrastructure while offering the best possible service to customers. The timetable integrates the potential of the network and the performances of the rolling stock with passenger expectation of frequent, fast and punctual services. A careful timetable planning process allows to increase the number of services and their reliability considering the requirements of the different services. Using a unique mix of conventional and advanced techniques developed in-house and awarded internationally, Lift leads the way towards optimal timetables. From South America to Norway, Lift planned timetables on urban, high-speed and mixed-traffic lines, with poor traffic or in saturated conditions, with a special focus on large, complex nodes.

PUNCTUALTY ESTIMATIONS

INNOVATIVE METHODS TO TEST THE QUALITY OF YOUR TIMETABLE STABILITY AND PUNCTUALITY ESTIMATIONS

We assess ex ante the reliability of timetables and compute infrastructure capacity according to given punctuality rates.

Punctuality has become fundamental for all stakeholders involved in railway operations, since delays lead to higher costs and lower customer satisfaction. Through advanced stochastic microsimulation, our innovative approach reproduces real traffic with the highest detail considering multiple operating days.

For instance, different delay scenarios can be defined to evaluate how the perturbation on one branch line impacts on the others in a complex node. This powerful and innovative method has been applied to large and complex networks, such as the lines and nodes between Milan and Bologna in Italy, supporting planners in multiple tasks:

  • Estimating the reliability that could be obtained with a given timetable;
  • Comparing the performances of different timetables;
  • Assessing the effects of delay propagation among lines and nodes;
  • Assessing the effects of selected delayed services on the others;
  • Estimating the capacity related to given reliability levels;

TEMPORARY TIMETABLES

DEFINITION OF TEMPORARY TIMETABLES DURING INFRASTRUCTURE IMPROVEMENT WORKS.

Design of Timetables that minimize delays due to infrastructure unavailability.

Infrastructure improvement works or major disruptions can limit the availability of railway lines and stations for long periods. If the regular timetable would be operated in such conditions, it would lead to major delays. At the same time, any reduction in the number of provided services causes a loss in railway attractiveness with respect to the other transport means.

At Lift, maximizing services while maintaining high punctuality levels is a constant focus. A long experience in a variety of contexts drives the development of innovative, quantitative approaches that support the delivery of effective temporary timetables.

The use of advanced simulation techniques allows to compare different alternatives, define possible timetable changes or request slight variations of work-related restrictions, with the aim of maximizing punctuality.
