CROSSRAIL, LONDON

TIMETABLE DESIGN USING INNOVATIVE TECHNIQUES AND ADVANCED SIMULATION TO ESTIMATE DELAYS

The ambitions and world-famous Crossrail line will bring about 1,5 more people at commuting time from central London and greatly relieve congestion on the overcrowded Central line of the Underground.
The infrastructure Manager RFL aims at selecting an operator that guarantees the maximum quality of service. It is obtained through a series of indicators, in which a key role is played by the punctuality and reliability.
Our task was to create a microscopic simulation model of the entire network, and simulate it using the timetable provided by RFL.
Second, TRENOlab created a new timetable from scratch, aimed at better exploiting the line and being flexible towards changes in the service requirements. We developed ad-hoc an additional functionality in the TRENOPlus timetable planning tool to create a timetable for a metro system in a few clicks.
The timetable was simulated considering real input delays obtained analyzing the existing network with TRENOAnalysis. Simulation was used to quantify the delays and variations of service frequency, for which the operator would have to pay.
