The execution of lane changes has a strong impact on driving safety and traffic throughput. Therefore, it is highly desired to automate and coordinate lane changes. The subject of this paper is the scheduling of lane changes of a group of connected and autonomous vehicles (CAVs) with the aim of minimizing the time during which all lane changes are completed, while keeping small inter-vehicle distances. To this end, the paper first develops an algorithm for minimizing the lane change time of a single CAV. This algorithm is then successively applied to all lane-changing CAVs. As a special feature, the proposed algorithm analytically computes CAV reference trajectories based on a second-order vehicle model such that all computations can be carried out in real time. In addition, the developed method supports the implementation of the computed CAV trajectories using cooperative adaptive cruise control in order to ensure safe driving in a tight vehicle formation. Detailed simulation experiments and a comparison to a benchmark method demonstrate the superior performance of our method.

Lane Change Scheduling for Autonomous Vehicles
Schmidt, Klaus Verner; Schmidt, Şenan Ece (2016-05-20)
The subject of this paper is the coordination of lane changes of autonomous vehicles on a two-lane road segment before reaching a given critical position. We first develop an algorithm that performs a lane change of a single vehicle in the shortest possible time. This algorithm is then applied iteratively in order to handle all lane changes required on the considered road segment while guaranteeing traffic safety. Various example scenarios illustrate the functionality of our algorithm.
Communication and coordination for urban intelligent transportation: architecture and algorithms
Atagoziev, Maksat; Schmidt, Klaus Verner; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2022-2-10)
In the scope of Intelligent Transportation Systems (ITS), the automation and coordination of connected and autonomous vehicle (CAV) lane changes (LCs) have a strong impact on driving safety and traffic throughput. Accordingly, this thesis develops algorithms for the coordination of CAV LCs that are then used for controlling the traffic at intersections. First, this thesis focuses on the coordination of LCs of a group of CAVs to minimize the time when all LCs are completed, while keeping small inter-vehicle ...
Design, analysis and experimental study of a novel side thorax impactor to be used in pedestrian protection tests for flat front vehicles
Saraç Karadeniz, Sevgi; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2021-10)
Pedestrian protection is crucial and the vehicle manufacturers put more and more effort to make vehicles safer for pedestrians in case of pedestrian involved accidents. Injuries and fatalities are very frequent and severe in pedestrian involved accidents because the pedestrians are much more vulnerable when compared to the vehicle occupants as they do not have any protection like airbags or seatbelts. The current pedestrian protection regulations focus on the tests of bonnet type passenger cars for the head...
Investigation of Traffic Safety Effects of Speed Limit Increases in Main Arterials
Türe Kibar, Funda; Tüydeş Yaman, Hediye (2018-09-30)
Setting safe speed limits requires consideration of different factors (operating speeds, road hierarchy, etc.), especially in urban corridors. With a legislative change, speed limits were increased from 50 km/hr by 32 km/hr on some urban arterials in Turkey, effect of which is examined for Ankara urban arterials in this study. Shifts in traffic accident hotspots, which were determined using Nearest Neighborhood Hierarchical (NNH) Clustering in Geographical Information System (GIS) environment, are quantifie...
Evaluation of pedestrian safety around bus stops using geographic information systems
Yüksekol, İrem; Tüydeş Yaman, Hediye; Department of Civil Engineering (2012)
Pedestrians are the most vulnerable road users in terms of traffic safety. Public transit users mostly have a pedestrian trip before and/or after the transit one. Thus, pedestrian activity is produced at transit stops naturally. The main focus of this study is pedestrian safety problems around transit stops, more specifically bus stops. The proposed methodology first includes Geographic Information Systems (GIS) analyses of the pedestrian safety along the study corridors and around bus stops on them; this e...
