Evolutionary modeling of large-scale public transport networks
(2018)2018 TRB Annual Meeting OnlineA genetic algorithm to design efficient large-scale public transport networks is extended. It goes beyond existing approaches by incorporating a dynamic demand response towards both changes in the network and external disruptions. The algorithm is based on an agent-based (MATSim) simulation and tested for the city of Zurich. Compared to the existing public transport system, it proposes a sparser network with substantially higher frequencies. ...Conference Paper -
Avoiding stranded bicycles in free-floating bicycle-sharing systems
(2019)2019 IEEE Intelligent Transportation Systems Conference (ITSC)In order to increase the number of bookings and revenue, most free-floating (electric) bicycle sharing operators periodically move bicycles to high demand areas (a process known as rebalancing). As rebalancing is time and cost inten- sive, an important question that arises is which bikes should be moved and which bikes are expected to be booked by the users within an acceptable period of time. In this paper, two survival analysis methods ...Conference Paper -

Evaluating London's congestion charge
(2018)The rationale of road-pricing schemes is to reduce the negative externalities of road traffic by increasing costs to decrease demand. Although in the transportation literature this is a well-acknowledged means of relieving cities from congestion, only few cities have introduced such schemes so far. One of the most notable examples in Europe is London’s congestion charge. Motorists entering London’s city center are required to pay a fixed ...Conference Paper -
Modeling free-floating car-sharing use in Switzerland
(2017)Free-floating car-sharing has been one of the latest innovations in the car-sharing market. It allows its customers to locate available vehicles via a smartphone app and reserve them for a short time prior to their rental. Because it is available for point-to-point trips, free-floating car-sharing is not only an alternative to private cars, but also to public transportation. Using spatial regression and conditional logit analysis of ...Conference Paper -
Comparing car-sharing schemes in Switzerland
(2016)Free-floating car-sharing schemes operate without fixed car-sharing stations, ahead reservations or return-trip requirements. Providing fast and convenient motorization, they attract both public transportation users and (former) car-owners. However, given their highly flexible nature and different pricing structures, previous findings on user groups and environmental impact of station-based car-sharing may not be easily transferable. ...Conference Paper -
