Article
Train movement dynamics are usually modelled by means of Newton’s second law. The resulting dynamic equation can be very precise if the parameters that it depends on are determined accurately. However, these parameters may vary in time and show wide variations, making the calibration task nontrivial and jeopardizing the performance of a broad varie...

With the arrival of COVID-19 in the Netherlands in Spring 2020 and the start of the “intelligent lockdown”, daily life changed drastically. The working population was urged to telework as much as possible. However, not everyone had a suitable job for teleworking or liked teleworking. From a mobility perspective, teleworking was considered a suitabl...
Article
Full-text available
Perceived travel times of travelers are usually longer than actually realized travel times, implying that passengers’ experience of travel time savings is different from objectively calculated savings. This study provides additional empirical evidence on this topic, by comparing the passengers’ perceived travel times reported in an (online) survey...
Article
Full-text available
Unreliable waiting times may cause frustration and anxiety amongst public transport travellers. Although the effect of travel time reliability has been studied extensively, most studies have used stated preferences which have disadvantages, such as an inherent hypothetical bias, or have analysed revealed preferences for road traffic. Here, we deriv...
Article
In this study a unique bicycle sharing program (BSP) is studied: a BSP initiated by an urban transit provider (buses and trams). The idea is that the combined use of BSPs and buses and trams could increase the catchment area of urban transit alone, therefore offering a more competitive alternative for the car. However, in the scientific literature...

Full-text available
Circuity of transit networks, defined as the ratio of network to Euclidean distance traveled from origin to destination stop, has been known to influence travel behavior. In addition to the longer time spent in travel, for networks where fare is based on distance traveled, higher circuity also means higher fare for the same Euclidean distance. This...

Shared transport creates an opportunity to facilitate the last mile connections of public transport (PT) trips. Nevertheless, user preferences for using such shared modes as last-mile connection have hardly been studied. To explore such preferences within urban areas we have designed and conducted a stated choice experiment in the province of Utrec...
Conference Paper
Waiting time has been consistently shown to have significant impact on route choice behaviour in public transport networks. Furthermore, unreliability in this component may cause frustration and anxiety in travellers.
