Beyond a complete failure: The impact of partial capacity reductions on public transport network vulnerability

Disruptions often result with partial capacity reduction without resulting with a complete breakdown. This study aims to move beyond the analysis of complete failure by investigating the impacts of partial capacity reduction on public transport network performance. We analyse the relation between the extent of capacity reduction at the line...

Exposing the role of exposure: Identifying and evaluating critical links in public transport networks

Network vulnerability depends on the probability that adverse events occur and on the impacts of such disruptions on network functionality. Most studies on transport network vulnerability have only analysed vulnerability in terms of the reduction in performance indicators given that a disruption occurs. This study presents and applies a method...

What big data do not tell us: What we can learn from travel survey for bus and lightrail in the Netherlands

With the introduction of the chipcardfor public transport (OV-chipkaart) as a digital ticketing system in the Dutch public transport (PT), a new data source for PT was created. The data registered by this smartcard contain every transaction (check-ins and check-outs) with according time and location. In 2013, the OV-chipkaart system operator...

Optimizing public transport planning and operations using automatic vehicle location data: The Dutch example

There is a growing pressure on urban public transport companies and authorities to improve efficiency, stemming from reduced budgets, political expectations and competition between operators. In order to find inefficiencies, bottlenecks and potentials in the public transport service, it is useful to learn from recorded operational data. We first...
