The market share of mobility on-demand (MoD) services strongly increased in recent years and is expected to rise even higher once vehicle automation is fully available. These services might reduce space consumption in cities as fewer parking spaces are required if private vehicle trips are replaced. If rides are shared additionally, occupancy relat...

Conference Paper
The last decade saw the emergence of ride-hailing (RH) services provided by private sector mobility service providers (MSPs). The RH operations usually accumulate customers into batches using fixed time period before assigning vehicles with optimal immediate profit. In the long run, this results in some regions having vehicles oversupply while othe...
Conference Paper

Article
Full-text available
Ride hailing (RH) services have become a common mode of transportation in the last decade. Usually, statistical tools are used to improve their performance, whereby the tools typically divide the whole operational area into multiple regions. These tools usually assume that the regions are independent of each other even though vehicles from one regi...
Article
This paper presents a two-step information system for operating an on-demand mobility (ODM) service using the advantages of both immediate responses based on heuristics and global (re)optimization of car–passenger assignments. Service providers using such a model can offer a better user experience due to shorter response times, while they also bene...

Conference Paper
Dynamic Car-Passenger Matching is a variant of the Dial-a-Ride Problem (DaRP) and a crucial part of operating an On-Demand Mobility (ODM) service. The ODM fleet management algorithm has to be able to find close-to-optimal solutions quick and reliable in order to provide a high quality service to the users of the service. In this work, an approach i...

Conference Paper
Ride sharing services have the potential to improve the traffic situation in urban areas. However, a successful implementation of such a service depends on the customers’ willingness to share their trip with somebody else, which among other factors depends on service quality factors. A ride sharing service is more attractive to the customers when i...
Conference Paper
Autonomous on-demand mobility systems, especially ride-pooling services, except for providing convenient transportation for the people, could potentially improve the traffic congestion in urban environments by reducing the number of private vehicles. In this paper, we introduce an Autonomous On-Demand Ride-Pooling (AODRP) system, which uses a rathe...
Presentation
Ride sharing demand will potentially increase with higher user convenience, however constraints on service quality parameters, such as detour time, waiting time of the customer or the time to board or disembark the vehicle, decrease the portion of trips that can be shared, a quantity called shareability. This study investigates this trade-off for v...
Conference Paper
Simulation frameworks for autonomous mobility-on-demand (AMoD) systems are currently implemented as round-based games, where the real-world simulation time effectively stops until the fleet operator and users finish their decision-making processes. As such, these decisions, which take time to complete in the real-world, are unrealistically treated...
Conference Paper
Ride sharing offers great potential to decrease the number of vehicles in the street and improve traffic congestion, if the customers are willing to share a ride and accept a certain deviation from their direct travel route. The demand for ride sharing will probably increase with higher user convenience. However, constraints on detour time, waiting...

Job opportunities affect the attractiveness of cities significantly. Since finding a place to live near the workplace is difficult in a lot of cases, many people have to commute by car or public transport. Especially commutes by private vehicle cause congestion, emissions and parking pressure. This work aims to design a shuttle service for employee...
Article
When considering autonomous mobility on demand (AMoD) trends, it is probably safe to assume that they will have a large market share in the near future. In the introductory phases, users of current non-autonomous mobility on demand services such as ride-hailing and carsharing are expected to be among the first users of AMoD systems. The research pr...
Conference Paper
With the introduction of autonomous vehicles, ride-hailing, taxi, and carsharing might all become on-demand door-to-door mobility services. We assume that the carsharing mode will develop into a system with more flexibility for users while ride-hailing and taxi will focus on the efficiency of the system. The flexibility of the autonomous carsharing...

Studies about autonomous taxis (aTaxis) concluded that empty vehicle movements account for a share of about 10% of the total fleet mileage. In most of these studies, static traffic representations are used, neglecting the effect of the aTaxis on the flows and velocities in the network. Moreover, these static representations do not consider traffic...
Conference Paper
Studies about autonomous taxis (aTaxis) concluded that empty vehicle movements account for a share of about 10% of vehicle miles traveled. In many of these studies, constant (in time or space) travel times are used due to a lack of data and to simplify the computations. Furthermore, the influence of the empty vehicle movements on the street network...
