A Data-Driven Approach for Generation of Tactical Planning Rules Regarding Buffer Time in Initial Railway Timetables: A Case Study on the Differentiation of Buffer Times in the Railway Timetable of Nederlandse Spoorwegen

Despite advanced communication, monitoring, and control facilities, train operations are still subject to uncertainties that can disturb train services, cause delay to multiple trains, and propagate through the network. One option is to mitigate delay propagation in the timetable design by adding buffer time to the minimum difference between the...

An Optimization Model for Simultaneous Periodic Timetable Generation and Stability Analysis

We present an optimization model which is able to generate feasible periodic timetables for networks given the line structure and the requested line frequencies, taking into account infrastructure constraints and train overtake locations. As the model uses the minimum cycle time as the objective function, the stability of the timetable is also...

The impact of scheduling on service reliability: Trip-time determination and holding points in long-headway services

This paper presents research on optimizing service reliability of longheadway services in urban public transport. Setting the driving time, and thus the departure time at stops, is an important decision when optimizing reliability in urban public transport. The choice of the percentile out of historical data determines the probability of being...

Service reliability and urban public transport design

The last few decades have shown a substantial increase in personal mobility. Urban traffic and transport volumes have been increasing for years. However, the share of public transport in this mobility growth did not change much and still remains rather limited. To ensure the accessibility and liveability of our cities for future generations,...
