On the Relocation Behavior of Ride-sourcing Drivers

Ashkrof, P. (author), Correia, Gonçalo (author), Cats, O. (author), van Arem, B. (author)

Ride-sourcing drivers, as individual service suppliers, can freely adopt their own relocation strategies, including waiting, cruising freely, or following the platform recommendations. These decisions substantially impact the balance between supply and demand, and consequently affect system performance. We conducted a stated choice experiment...

Ride acceptance behaviour of ride-sourcing drivers

Ashkrof, P. (author), Correia, Gonçalo (author), Cats, O. (author), van Arem, B. (author)

The performance of ride-sourcing services such as Uber and Lyft is determined by the collective choices of individual drivers who are not only chauffeurs but private fleet providers. In such a context, ride-sourcing drivers are free to decide whether to accept or decline ride requests assigned by the ride-hailing platform. Drivers’ ride...

How do dutch drivers perceive horizontal curves on freeway interchanges and which cues influence their speed choice?

Vos, J. (author), Farah, H. (author), Hagenzieker, Marjan (author)

Operating speeds in Dutch freeway curves differ often by 20 km/h compared to their design speeds. Operating speed is thought to be influenced by how drivers perceive curves when approaching a curve. This explorative research explores which curve cues and other variables influence drivers’ speed choice in curves. For this purpose, a survey was...

Driver speed compliance following automatic incident detection: Insights from a naturalistic driving study

Varotto, Silvia F. (author), Jansen, Reinier (author), Bijleveld, Frits (author), van Nes, C.N. (author)

Automatic incident detection (AID) systems and variable speed limits (VSLs) can reduce crash probability and traffic congestion. Studies based on loop detector data have shown that AID systems decrease the variation in speeds between drivers. Despite the impact on driver behaviour characteristics, most mathematical models evaluating the...

Adaptations in driver deceleration behaviour with automatic incident detection: A naturalistic driving study

Varotto, Silvia F. (author), Jansen, Reinier (author), Bijleveld, Frits (author), van Nes, C.N. (author)

Traffic congestion and crash rates can be reduced by introducing variable speed limits (VSLs) and automatic incident detection (AID) systems. Previous findings based on loop detector measurements have revealed that drivers reduce their speeds while approaching traffic congestion when the AID system is active. Notwithstanding these behavioural...
