Autonomous on-demand mobility systems, especially ride-pooling services, except for providing convenient transportation the people, could potentially improve traffic congestion in urban environments by reducing number of private vehicles. In this paper, we introduce an On-Demand Ride-Pooling (AODRP) system, which uses a rather realistic customer-model that is sensitive to waiting times. To quantify benefits AODRP system have on city network, case study Munich performed with shared fleet...

Studies about autonomous taxis (aTaxis) concluded that empty vehicle movements account for a share of 10% miles traveled. In many these studies, constant (in time or space) travel times are used due to lack data and simplify the computations. Furthermore, influence on street network has not yet been focal point research. To address two issues, operation an aTaxi system is implemented into existing traffic microsimulation model. On one hand, depicts more accurately than link-level values....

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 fleet operator and users finish their decision-making processes.

Ride sharing offers great potential to decrease the number of vehicles in street and improve traffic congestion, if customers are willing share a ride accept certain deviation from their direct travel route. The demand for will probably increase with higher user convenience. However, constraints on detour time, waiting time or even amount board disembark vehicle, chances find shared trips. This paper investigates this trade off by analyzing impacts service quality factors trips which could...

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 typically divide whole operational area into multiple regions. These usually assume that regions independent each other even though vehicles from one region can be serve neighboring regions, thereby method is required consistently relates vehicle demand and supply between geographically or operating area. This hinders tapping...

Ride sharing services have the potential to improve traffic situation in urban areas. However, a successful implementation of such service depends on customers' willingness share their trip with somebody else, which among other factors quality factors. A ride is more attractive customers when it associated short detour and waiting time. Hence, from an operator perspective these constrain chances find shareable trips. reservation-based system might be beneficial increase chances. The aim this...
