Intelligent Transportation Systems (ITS) is becoming an important paradigm, because of its ability to enhance safety and to mitigate congestion on road traffic scenarios. Realizing the fact that data collection scheme from in-situ test beds for large number of vehicles is always expensive and time consuming, before being employed in large scale, such safety critical system should be tested narrowing down the gap between real circumstances and analytical models in a simulation platform. It is evident that underlying radio wave propagation models can comprise the validity of large scale vehicular network simulation results. Vehicle-to-Vehicle (V2V) channels have higher dynamics due to rapidly varying topologies and environments which have significant impact on performance study of upper layer protocols and applications. In spite of the fact that few measurement based empirical channel models are present in the literature, they are not tested for large scale vehicular networks. In this study, we simulate suburban scenarios with hundreds of IEEE802.11p nodes in the OPNET simulation environment with more realistic channel models. The standard OPNET propagation model was replaced by Nakagami-m fading channel. For the sake of modeling, changing relative velocity attribute and separation distance, power spectrum and fading parameter-m were defined as function of velocity and separation distance respectively. Then statistics were collected to evaluate performance of physical and higher layers. Primarily we have found all the vehicles within the standard requirement for Dedicated Short Range Communications (DSRC) range of 1 kilometer may not receive packets, which was also found in several earlier publications.

Exploring critical success factors for blockchain-based intelligent transportation systems Çaldağ, Murat Tahir; Gökalp, Ebru (2020-01-01) Utilization of Intelligent Transportation Systems (ITS) provides increasing demands on decreasing traffic congestions, transportation safety, and environmental problems as well as increasing transportation capacity. Over the past few years, one of the most disruptive and transformational technologies, blockchain technology, has emerged. As a result of offering more security, privacy, traceability, transparency, and decentralized authority, the utilization of blockchain technology in ITS have increased drast...
Comparison of cooperative adaptive cruise control methods in idealistic and realistic scenarios Aydın, Ahmed Buğra; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2021-9-10) Intelligent transportation systems (ITS) aim at improving the efficiency and safety of transportation. In dense traffic, vehicles are aggregated to vehicle strings that travel on the same lane, whereby it is desired to maintain a small but safe distance between the vehicles in order to ensure driving comfort and safety. Cooperative adaptive cruise control (CACC) is a technology that is developed to address this issue. Hereby, the condition of string stability is highly relevant since it ensures the attenuat...
Modeling of Bus Transit Driver Availability for Effective Emergency Evacuation in Disaster Relief Morgul, Ender Faruk; Cavus, Ozlem; Ozbay, Kaan; İyigün, Cem (2013-01-01) Potential evacuees without access to personal automobiles are expected to use transit, especially buses, to reach safer regions. For a transit agency, operation problems to be considered include establishing bus launch areas, positioning the minimum number of required buses, and coordinating transit operators, especially determining whether the number of drivers will be sufficient to cover the number of vehicles (i.e., buses) to be used during the evacuation. It is also highly probable that during an emerge...
Synthesis of formal control strategies for traffic systems Bardakçı, Kemal Çağrı; Aydın Göl, Ebru; Department of Computer Engineering (2018) The problems caused by traffic congestion affect human life adversely. Wasted amount of time, fuel and money as well as adverse effects to environment are examples of these problems which reduce life quality. Studies on traffic management underline importance of traffic network control mechanisms. Different configurations of roads and signalized intersections complicate interactions among vehicles and pedestrians. Hence, traffic control systems, which need to satisfy complex specifications, should be constr...
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 ...
