Ontsluitend ov
Dit weekend schreef Joost van Velzen in Trouw over de Hugohopper, een succesvol vervoerssysteem in de gemeente Dijk en Waard, dat naast bereikbaarheid ook voorziet in sociale cohesie.
De Hugohopper is een mooi voorbeeld van lokaal maatwerk voor de bereikbaarheid van minder drukke gebieden, als alternatief voor de ontsluitende bus. Aandachtspunt is wel integratie van informatie en betaling met gewoon ov, om ook bezoekers te faciliteren. De inzet van vrijwilligers is een kracht, maar kan op termijn ook een uitdaging vormen.
Het voorbeeld laat goed zien dat voor minder drukke gebieden en -tijden geen standaard ov-oplossing bestaat om geografische uitsluiting te voorkomen. In sommige gevallen volstaat de gewone bus, maar de buurtbus, flex-ov of bijvoorbeeld vervoer via verenigingen, zoals de HugoHopper, zijn soms betere oplossingen voor inclusieve mobiliteit. In ons onderzoek proberen we te begrijpen welk systeem waar en wanneer de beste oplossing biedt, passend bij de behoeften en kenmerken van de gebruikers én de maatschappelijke doelen en restricties.

MT-ITS conference: Identifying potential use of emerging neighbourhood mobility hubs using behavioural modelling
Neighbourhood mobility hubs may play an important role in mitigating the impact of passenger cars on climate change and urban public space. As a relatively new concept, academic research on the user potential of neighbourhood mobility hubs is so far limited. This research aims to identify which user groups are likely to adopt services offered by a neighbourhood mobility hub. A survey was distributed in the Netherlands (N=298) and an Exploratory Factor Analysis (EFA) and a Latent Class Cluster Analysis (LCCA) were executed. Four distinctive groups of intended users were uncovered. Two of the clusters have intentions to use neighbourhood mobility hubs. The other two identified clusters do not (yet) intend to use neighbourhood mobility hubs. The clusters indicate that people who currently already travel more by sustainable modes (train or (e-)bicycle) are more likely to be adopters of neighbourhood mobility hubs than the traditional car users. In practice, this may make the positive effect of hubs more limited than anticipated or even increase car use. However it could also facilitate those travelling sustainable to do so for longer as additional shared modes become available to them via hubs. Limitations and directions for further research are discussed.

PhD project: Robust train trajectory optimization
In cooperation with the Dutch Railways (NS), Alex Cunillera works in this PhD research on robust train trajectory optimization. Even two trains of the same model running on the same line show significant differences in their dynamics. This might be due to different passenger loads, weather, fault history, driving style of the train driver, etc. Moreover, there are uncertainties in the track data that may also have a strong influence on the train operation. This research focuses on determining the uncertainties and stochastics of these variations and developing methods to compute robust train trajectories that optimize the energy consumption and minimize delays in the presence of the mentioned variations.

Covid impacts on train travel behaviour
Delft University of Technology and the Dutch railways (NS) started a joint, longitudinal research in April 2020 on Covid impacts on train passenger behaviour. During the pandemic, 7 surveys in different stages (15,000-45,000 participants each) were held to learn about the impacts and expectations. The main results are presented in an infographic.

Micromobility and public transport
Following technological and societal developments, new modes and services arrive in our cities. Micromobility solutions, such as shared (e-)bikes and –scooters, are adding new opportunities for individuals, but what their (potential) contribution is to societal objectives such as sustainability, land use and inclusiveness, is not yet known. In order to gain this knowledge and optimize the mobility mix, the Smart Public Transport Lab investigates the demand and supply impacts and interaction of micromobility, including the interaction with public transport. In this infographic the main, recent results of the ongoing research are summarized.

Potential of on-demand services for urban travel (Flex-OV)
On-demand mobility services are promising to revolutionise urban travel, but preliminary studies are showing that they may actually increase the total vehicle miles travelled, thereby worsening road congestion in cities. In this study, we assess the demand for on-demand mobility services in urban areas,using a stated preference survey, to understand the potential impact of introducing on-demand services on the current modal split. The survey was carried out in the Netherlands and offered respondents a choice between bike, car, public transport and on-demand services. 1,063 valid responses are analysed with a multinomial logit and a latent class choice model. By means of the latter, we uncover four distinctive groups of travellers based on the observed choice behaviour. The majority of the sample (55%) are avid cyclists and do not see on-demand mobility as an alternative for making urban trips. Two classes (27% and 9% of the sample) would potentially use on-demand services: the former is fairly timesensitive and would thus use on-demand service if they were sufficiently fast. The latter class however is highly cost-sensitive, and would therefore use on-demand mobility primarily if it is cheap. The fourth class (9%) shows very limited potential for using on-demand services.

Ex-post evaluatie van mobiliteitshubs: Een kwalitatieve studie naar de factoren die het gebruik en de effecten van mobiliteitshubs beïnvloeden
Mobiliteitshubs zijn een veelbelovend concept dat steeds meer aandacht krijgt. Zo zijn er in de afgelopen twee jaar ongeveer 150 buurtmobiliteitshubs geopend in Nederland. Buurtmobiliteitshubs, een plek waar een aantal verschillende (deel)voertuigen worden aangeboden, worden gezien als een ondersteuner en versterker van deelmobiliteit. Zo kunnen deelmobiliteit en mobiliteitshubs aantrekkelijke alternatieven bieden voor privé voertuigen en bijdragen aan gemeentelijke beleidsdoelen. Vier grote thema’s zijn hierin te onderscheiden. Meestal gaat het over een verbetering in de openbare ruimte, duurzaamheidsdoelstellingen, reductie van privéauto’s en ambities wat betreft bereikbaarheid.

Deelvervoer in de provincie Utrecht: het potentieel gebruik in combinatie met OV.
De provincie Utrecht wil de verwachte reizigersgroei in het OV het hoofd bieden door in te zetten op meer kwaliteit voor de reiziger, duurzame en innovatieve mobiliteits-oplossingen en per gebied te kiezen voor de meest geschikte combinatie van vervoerwijzen. Hierbij past dit gebruikersonderzoek naar hoe lokaal OV (stad- en streekvervoer met bussen en trams) en deelmobiliteit in het voor- en natransport elkaar kunnen versterken. Dit sluit aan op het wetenschappelijk kennishiaat; er is helaas nog weinig bekend over het gebruik van deelvervoer in multi-modale ketens.

Train traveller behaviour during and after Covid: insights of a longitudinal survey of Dutch train passengers
The pandemic had (and still has) an obvious impact on public transport (use). To gain insights into passenger behaviour during and after the pandemic, a longitudinal survey is organised with the goal to capture behaviour, attitudes and intentions related to train usage. Four surveys were held between April and December 2020, involving 23,000-47,000 passengers each. The results provide valuable, quantitative insights that help to recover and rethink public transport after the pandemic, for instance by adjusted planning, design and operations. Findings show that 30% of the passengers want to avoid the peak hour after Covid and 72% will telework more often, saving multiple trips per week. The most popular days for teleworking will be Friday and Wednesday. Related future research directions are for instance developing more flexible and demand-driven schedules and services.
