The importance of V2X simulation: an in-depth comparison of intersection control algorithms
using a high-fidelity communication simulation

The rapid evolution of vehicle-to-vehicle and vehicle-to-infrastructure communication opens doors to various control algorithms, one particular domain being intersection control. Several researchers have proposed communication-based intersection control algorithms omitting traditional traffic lights with the promise of enhanced throughput and improved traffic safety. On the other hand, the majority of these algorithms ignore the uncertainties and […]

Mesoscopic traffic simulation to speed up EGO vehicle-centric simulation

Simulation-based testing of classical driver assistance functions (ABS, ESP) involves mainly the EGO vehicle and some dummy objects. Specifying the scenario in simulation is simple. However, testing complex, cooperative, or perception-based driver assistance functions (e.g., a traffic jam pilot) requires many vehicles inside the simulation. Therefore, microscopic traffic simulation is often used together with vehicle […]

Digital Twin of a road with the help of OpenCRG

The usage of sophisticated testing methods such as Vehicle-in-the-Loop, Scenario-in-the-Loop, and other mixed-reality systems is becoming inevitable in autonomous vehicle development. These methods rely on using digital twins, realistic representations of real vehicles and their environment (e.g. road, traffic) in a carefully built virtual world. If the testing task is such (e.g., vehicle dynamics simulation), […]

Urban Traffic Control for Autonomous Vehicles

A two-layer traffic control method is proposed to obtain an efficient traffic flow by removal of traffic light and velocity optimization of each individual vehicle in the vicinity of each junction and prioritizing the links to influence the traffic flow. The link prioritization is used for the macroscopic optimization of the system while the junction […]

Emission Modeling and Control

Emission Modeling Road traffic congestion has become an everyday phenomenon in today’s cities all around the world. The reason is clear: at peak hours, the road network operates at full capacity. In this way, growing traffic demand cannot be satisfied, not even with traffic-responsive signal plans. The external impacts of traffic congestion come with a […]

Data fusion for urban road traffic

The knowledge of road traffic parameters is of crucial importance to ensure state-of-the-art traffic services either in public or private transport. In our days, a plethora of road traffic data is continuously collected producing historical and real-time traffic information as well. The available information, however, arrives from inhomogeneous sensor systems. Therefore, data fusion methodologies are […]

Bus Bunching Control

On busy lanes, where public transport buses are frequent, bus bunching is a common phenomenon: Bunching leads to non-homogeneous utilization of buses and therefore degradation of service quality. The objective is to (i) adhere buses to a timetable and (ii) guarantee equal headways. The proposed control methodology is a shrinking horizon model predictive velocity control.  […]
