We propose an application of recent advances in e-cash, anonymous credentials, and proxy re-encryption to the problem of privacy in public transit systems with electronic ticketing. We discuss some of the interesting features of transit ticketing as a problem domain, and provide an architecture sufficient for the needs of a typical metropolitan transit system. Our system maintains the security ...

Cost-effective public transit options suitable for serving all demand levels include: bus service in mixed traffic, bus service in reserved lane, transitway/buswdy, light rail transit (LRT) (segregated right of way), intermediate capacity advanced light rail transit (ALRT), and heavy rail rapid transit. This classification of transit options takes into account right-of-way access (that is, mixe...

infrastructure development being the major construction activity undertaken with the support of the government to eradicate poor transport infrastructure, to cater to ever-increasing population, to reduce the usage of own vehicle and environmental impact thereof, the concept of mass rapid transit system came into existence. among the various mass rapid transit system modes, metro rail construct...

We study the problem of computing all Pareto-optimal journeys in a public transit network regarding the two criteria of arrival time and number of transfers taken. We take a novel approach, focusing on trips and transfers between them, allowing fine-grained modeling. Our experiments on the metropolitan network of London show that the algorithm computes full 24-hour profiles in 70 ms after a pre...

Public transport systems are confronted by the need to improve their economic effectiveness in order to meet customer requirements at acceptable costs for transit providers, which are often heavily subsidized. Our goal is to understand how the organizational form of the transit system impacts on system productivity. Our methodology consists of comparing performance in terms of distance traveled...

Every day, millions of people are transported by buses, trains, and airplanes in Germany. Public transit (PT) is of major importance for the quality of life of individuals as well as the productivity of entire regions. Quality and efficiency of PT systems depend on the political framework (state-run, market oriented) and the suitability of the infrastructure (railway tracks, airport locations),...

Abstract: The public transit system are essential services to the sustainability and livability of any city. Transit agencies are consistently trying to improve service reliability and attract passengers by applying various strategies. In this paper, we present an approach to mining the temporal behavior of the passengers in a public transportation system, which may help the transport operators...

Partitioning of public transit networks is a useful approach to speed up the query times or the preprocessing phase of public transit routing algorithms. The aim of partitioning of public transit networks is to find small partitions of the stations of a given network such that most of the traffic lies in their inside while only little traffic goes between them. To find such partitions of the pu...

We study the problem of computing all Pareto-optimal journeys in a dynamic public transit network for two criteria: arrival time and number of transfers. Existing algorithms consider this as a graph problem, and solve it using variants of Dijkstra’s algorithm. Unfortunately, this leads to either high query times or suboptimal solutions. We take a different approach. We introduce RAPTOR, our nov...
