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...

Ride-hailing business models have grown rapidly, but even the most successful companies have yet to achieve profitability. Providers fight for market share with low prices and incentives, expecting to achieve profitability after gaining market power. However, there is no existing research on what makes providers profitable depending on the competit...

In order to investigate the interaction between automated vehicles (AVs) and bicyclists, we present a coupled driving simulator that enables these two traffic participants to interact in a virtual environment. To avoid potentially dangerous situations in road traffic, human perception can be extended by communication between vehicles and their envi...
Conference Paper
While internal combustion engine (ICE) vehicles are a major contributor to greenhouse gases, electric vehicles (EVs) have proven their potential to achieve eco-friendly transportation. To date, the usage of EVs is limited mainly due to their short driving range and relatively long charging times as well as their insufficient charging infrastructure...
Article
Virtual traffic environments allow for evaluations of automated driving functions as well as future mobility services. As a key component of this virtual proving ground, a traffic flow simulation is necessary to represent real-world traffic conditions. Real-world observations, such as historical traffic counts and traffic light state information, p...

Short-term disruptions can have a long-lasting negative effect on traffic flow exceeding the duration of the disruption itself. This is especially the case when traffic demand approaches the network’s capacity. On-demand ride-sourcing services like ride-hailing and ride-pooling do not only have an impact on the overall kilometers driven in a networ...

In spring 2022, the German federal government agreed on a set of measures that aim at reducing households' financial burden resulting from a recent price increase, especially in energy and mobility. These measures include among others, a nation-wide public transport ticket for 9 EUR per month and a fuel tax cut that reduces fuel prices by more than...
Conference Paper
While traffic lanes were initially introduced as essential instruments for simplifying driving tasks for human drivers and increasing traffic safety, their necessity with the emergence and advancement of connected and automated vehicles (CAVs) has to be questioned (Papageorgiou et al., 2021). CAVs are equipped with highly precise sensors and smart...

Article
Compared with public transport operations, urban freight traffic and its associated delivery operations seem to be frequently overlooked in urban traffic management and traffic flow theory. One explanation for this is certainly the lack of available data, as the competitive freight transport market is fragmented and several actors are unwilling to...
Conference Paper
Full-text available
Explicit and implicit communication cues are part of the communication strategies often employed by bicyclists in traffic to reveal their intentions to other road users. For human drivers, such types of information may be understandable in a specific social and cultural context. Present automated driving functions mostly rely on vulnerable road use...

In recent years, there have been intensive efforts to consider human factors (HFs) in the modeling of human driver behavior. In particular, “engineering” car-following models widely used in traffic simulation have been extended to include HFs. This extension is needed to generate critical situations, which are often attributable to human error. How...

When planning road networks, inhomogeneous traffic conditions and the effects of multimodal interactions are often neglected. This can lead to a substantial overestimation of network capacities. Empirical macroscopic fundamental diagrams (MFDs) or volume delay relationships show considerable scatter, reflecting a reduction in network performance an...

In the last decades, free-floating carsharing (FFCS) systems were established all over the world besides other mobility-on-demand systems. These systems represent a promising alternative to the privately owned vehicle as they offer a high degree of flexibility in usage. However, profitability and customer satisfaction depend strongly on how the sys...

Predicting freeway traffic states is, so far, based on predicting speeds or traffic volumes with various methodological approaches ranging from statistical modeling to deep learning. Traffic on freeways, however, follows patterns in space-time like stop and go waves or mega jams. These patterns by itself are informative because they propagate in sp...

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...
