Fleet size determination for a mixed private and pooled on-demand system with elastic demand

The recent emergence of innovative mobility solutions is changing the mobility landscape in urban areas. However, it remains unknown how the combined operation of private and pooled on-demand services affect service performance and the required dimensioning of the fleet size for such services. This study develops a model to determine the...

Determinants of urban wayfinding styles

Everyday people find their way towards work, supermarkets, or unfamiliar places are explored for a social visit. Understanding how differences in urban wayfinding behaviour relate to daily travel patterns is important to describe route choice behaviour, identify potential navigation problems, design more legible cities, and provide...

Robust Control for Regulating Frequent Bus Service: Supporting the Implementation of Headway-Based Holding Strategies

Reliability is a key determinant of the quality of a transit service. Control is needed to deal with the stochastic nature of high-frequency bus services and to improve service reliability. This study focuses on holding control, both schedule- and headway-based strategies. An assessment framework is developed to systematically assess the effect...

Latent classes of daily mobility patterns: the relationship with attitudes towards modes

Active modes (i.e. walking and cycling) have received significant attention by governments worldwide, due to the benefits related to the use of these modes. Consequently, governments are aiming for a modal shift from motorised to active modes. Attitudes are generally considered to play an important role in travel behaviour. Understanding the...

Cycling or walking? Determinants of mode choice in the Netherlands

Interest into active modes (i.e. walking and cycling) has increased significantly over the past decades, with governments worldwide ultimately aiming for a modal shift towards active modes. To devise policies that promote this goal, understanding the determinants that influence the choice for an active mode is essential. The Netherlands is...

Where shall we sync? Clustering passenger flows to identify urban public transport hubs and their key synchronization priorities

Minimizing passenger transfer times through public transport (PT) transfer synchronization is important during tactical planning and real-time control. However, there are computational challenges for solving this Timetable Synchronization Problem (TSP) for large, real-world urban PT networks. Hence, in this study we propose a data-driven,...

Passenger Travel Time Reliability for Multimodal Public Transport Journeys

Urban transit networks typically consist of multiple modes and the journeys may involve a transfer within or across modes. Therefore, the passenger experience of travel time reliability is based on the whole journey experience including the transfers. Although the impact of transfers on reliability has been highlighted in the literature, the...

Evaluating a data-driven approach for choice set identification using GPS bicycle route choice data from Amsterdam

Specifying the choice set for travel behaviour analysis is a non-trivial task. Its size and composition are known to influence the results of model estimation and prediction. Most studies specify the choice set using choice set generation algorithms. These methods can introduce two types of errors to the specified choice set: false negative ...

On-demand diensten onderzoeken met agent-based model

Binnen het concept van Mobility-as-a-Service nemen de ‘vervoersdiensten op aanvraag’, vervoer wanneer en hoe we het willen, een belangrijke plek in. Wat is het potentieel van deze diensten? En als ze eenmaal geïmplementeerd zijn, wat betekent dat dan voor de prestatie van het vervoerssysteem als geheel? PhD’er Jishnu Naraya van TU Delft deed...

The Potential of Demand-Responsive Transport as a Complement to Public Transport: An Assessment Framework and an Empirical Evaluation

Demand-responsive transport (DRT) services (collective on-demand services, such as shared ridesourcing and microtransit) offer a collective flexible travel alternative that can potentially complement fixed transit (FT). The combination of an on-demand and line-based service holds the promise of improved mobility and increased service coverage...

How do people cycle in Amsterdam, Netherlands?: Estimating cyclists' route choice determinants with GPS data from an urban area

Nowadays, the bicycle is seen as a sustainable and healthy substitute for<br/>the car in urban environments. The Netherlands is the leading country<br/>in bicycle use, especially in urban environments. Yet route choice models<br/>featuring inner-city travel that includes cyclists are lacking. This study<br/>estimated a cyclists’ route choice...
