Insights into factors affecting the combined bicycle-transit mode
The combination of bicycle and transit is an upcoming, sustainable multimodality. The flexibility of the bicycle combined with the speed and comfort of good transit can be a highly competitive alternative to the car. This study shows that many factors influence the uptake and attractiveness of the bicycle-transit combination. An in-depth literature review resulted in over thirty unique factors: six transit related factors, twenty first-last mile factors and fifteen context related factors. All these factors might influence the demand for this ‘new’ mode positively or negatively. An exploratory choice modelling study showed that Dutch bicycle-train users in our sample are willing to pay €0.11 for a minute less bicycle time, €0.08 for a minute less train time, €0.11 for a minute of less time to park and €0.60 per avoided transfer. These kinds of insights give the bicycle and transit sector valuable information to be used in modelling multimodality and cost-benefit analyses, thereby supporting improved decision making and integrated design of bicycle and transit networks.

Van B naar Anders
Op woensdag 30 mei organiseerde de Rli naar aanleiding van zijn advies een symposium. Tijdens dit symposium is het advies toegelicht en met betrokkenen uit de mobiliteitswereld besproken. Daarbij wordt stilgestaan bij de toekomst van mobiliteit en infrastructuur, de bestuurlijke praktijk en bij innovatie en verduurzaming van ons mobiliteitssysteem.

Assessing and improving operational strategies for the benefit of passengers in rail-bound urban transport systems
Unplanned disruptions in transit can have consequent impacts on passengers. The more inconvenienced passengers are, the more likely operators will be negatively impacted. Yet so far, operators and researchers have addressed the rescheduling problem during disruptions mainly with a supply-side focus – timetable, crews and vehicles – and not with a passenger perspective. Urban rail transit particularly lacks insights in terms of passenger- focused rescheduling. Being able to assess the inconvenience experienced by passengers during disruptions compared with what they normally experience, and being able to compare how different rescheduling strategies affect them are therefore two major challenges.
The framework developed in this study precisely aims at tackling 8 these challenges. A case study of the metro of Rotterdam is used to test the framework developed in this paper. Alternative strategies are developed focusing on the incident phase (from the beginning of the incident until its cause is resolved). The application of the framework reveals that a regularity-focused rescheduling strategy would be beneficial for high-frequency service users. Realistically, yearly savings could amount to around €900,000 in terms of societal passenger costs for the operator in the Rotterdam area alone. However, the omnipresence of the punctuality paradigm, through which most operators plan and analyze operations, makes the implementation of passenger-focused strategies a challenging task for traffic controllers. The results of the study are valuable for transit operators worldwide and the framework can provide insights to decision-makers on the performance of different strategies, bringing to light trade-offs between supply and passenger sides during disruptions.

The Potential of Demand Responsive Transport as a Complement to Public Transport
Demand Responsive Transport (DRT) offers a collective flexible travel alternative that can potentially complement Fixed Transit (FT). The combination of an on-demand and line-based services holds the promise of improved mobility and increased service coverage. However, insofar it remains unknown whether DRT services deliver such much anticipated improvements.
This study presents an assessment framework to evaluate the performance of DRT and related changes in accessibility and performs an empirical analysis for a recently introduced DRT service in the Netherlands. The framework includes a performance benchmark between DRT and FT based on the computation of generalized journey times of the DRT rides and the FT alternatives, and it can help identify whether DRT is used as complement or substitute of FT.
The framework covers the spatial and temporal dimensions, and the explicit consideration of rejected trips is an integral part of the evaluation. Results suggest large accessibility improvements for DRT users, especially for some underserved origin-destination pairs.
