Quantification and control of disruption propagation in multi-level public transport networks

Yap, M.D. (author), Cats, O. (author), Törnquist Krasemann, Johanna (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Due to the multi-level nature of public transport networks, disruption impacts may spill-over beyond the primary effects occurring at the disrupted network level. During a public transport disruption, it is therefore important to quantify and control the disruption impacts for the total public transport network, instead of delimiting the...

Perception of overlap in multi-modal urban transit route choice

Dixit, M. (author), Cats, O. (author), Brands, T. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Capturing unobserved correlation between overlapping routes is a non-trivial problem in route choice modelling. For urban transit networks, research so far has been inconclusive on how this overlap is perceived by travellers. We estimate a series of path size correction logit (PSCL) models to account for alternative specifications of route...

Examining circuity of urban transit networks from an equity perspective

Dixit, M. (author), Chowdhury, S.J. (author), Cats, O. (author), Brands, T. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

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...

On the influence of cost and time on the willingness to share a ride: A scenario analysis (PPT)

Alonso González, M.J. (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn-Lanser, S. (author), Hoogendoorn, S.P. (author)

Simulation studies suggest that pooled on-demand services (also referred to as ridesplitting or shared ride-hailing/ridesourcing services) have the potential to bring large benefits to urban areas with little time loss for their users. However, the large majority of on-demand requests in existing services are for individual rides. In this study,...

Value of time and reliability for urban pooled on-demand services

Alonso González, M.J. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn-Lanser, S. (author), Hoogendoorn, S.P. (author)

The uptake of on-demand services is increasing rapidly all over the world. However, the market share of their pooled version (ridesharing, e.g., UberPOOL or LyftLine) is still low, despite its potential in addressing the mobility challenges that dense urban cities are facing. In this research, we analyse user preferences towards pooled on-demand...
