PCIMS: plenary centralized intersection management scheme for heterogeneous connected vehicles. - In: 2023 IEEE International Conference on Omni-Layer Intelligent Systems (COINS), (2023), insges. 6 S.
This paper proposes a novel plenary centralized intersection management scheme (PCIMS) for a non-signalized intersection. Our contributions are fourfold. First, we take into account vehicle heterogeneity by integrating various vehicle classes in the system. Second, we consider some key elements in the scheduling mechanism such as vehicle types, intersection rules and road priorities. Third, we discuss the significant role of different road conditions, specific vehicles behavior and safety parameters in the traffic safety. Forth, in addition to the traffic safety assurance, we demonstrate the superiority of the system performance over conventional traffic lights (TLs) in several scenarios with congested and sparse traffic in terms of average travel time (ATT), packet loss rate (PLR), channel busy rate (CBR), intersection busy time (IBT), and throughput.

Plenary autonomous intersection management protocol for heterogeneous connected vehicles. - In: ICUFN 2023, (2023), S. 334-336
This paper proposes a centralized autonomous intersection management scheme for heterogeneous connected vehicles (HCVs). Contributions of this work are as follows. First, we sustainably classify heterogeneous vehicles with their distinctive safety-related characteristics. Second, we conduct a safe and efficient coordination algorithm with respect to some criteria such as vehicle types, road priorities and right of way rules. Third, we consider the impact of different road conditions, vehicle characteristics, load, and braking technology on the system performance. Forth, we demonstrate the efficiency of the system under various traffic densities with symmetric and asymmetric vehicle distribution. Besides, system performance is to be compared with traffic lights (TLs) scenarios in terms of throughput, average travel time (ATT), intersection busy time (IBT), channel busy rate (CBR), and packet loss rate (PLR) in various road conditions.

VANET-based traffic light management for an emergency vehicle. - In: Ubiquitous networking, (2023), S. 129-137
Wireless communications have affected our lifestyle in the last decades. It is helpful to improve quality of life for communities. Communications among vehicles usually take place in vehicular ad-hoc networks (VANETs). Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications are aspects of communications in the transportation which are growing rapidly. They can play a pivotal role in the transportation field. Management of traffic lights (TLs) is crucial to control traffic flow especially at an intersection. The goal of this paper is to manage the TLs at an intersection when an emergency vehicle (EV) is approaching. First, we simulate an intersection which includes TLs via simulation of urban mobility (SUMO). Later, we simulate VANETs communication to manage the TLs at the intersection when the EV is coming with the help of objective modular network testbed in C++ (OMNeT++) and vehicles in network simulation (Veins). Finally, the impact of V2I communication on delivery efficiency of the emergency service is investigated. Simulation results show an improvement in delivery efficiency of the emergency service.
Versatile safe autonomous intersection management protocol for heterogeneous connected vehicles. - In: 2022 IEEE Vehicle Power and Propulsion Conference (VPPC), (2022), insges. 7 S.
In this paper, we employ a novel safe centralized intersection management (IM) scheme for heterogeneous classes of connected vehicles such as passenger vehicles (PVs), buses, vans, trucks, emergency vehicles (EVs), trams and also vulnerable road users (VRUs) including motorcycles, bicycles, and moped. A rule-based algorithm undertakes safe coordination using different criteria such as intersection traffic rules, vehicle types and road priorities. Besides, in the proposed system, dynamics and behavior of the road users, which might be totally distinct, are taken into account. These underlying characteristic behaviors comprise of reaction distance $(D_r)$, stopping distance $(D_s)$, braking distance $(D_b)$, braking lag distance $(D_bl)$ as well as deceleration (d) and velocity (v) of the vehicles in an urban environment. In addition, special lanes for cyclists and tram tracks are considered in the layout. Furthermore, in order to more properly image the realistic traffic situations, we have integrated the impact of various road conditions in our system in terms of dry, wet, snowy, and icy. Performance of the system is analyzed in several sparse and dense traffic situations with respect to different criteria such as speed and travel time. Additionally, efficiency is also compared to traditional intersection management systems like traffic lights (TLs).

Empirical estimation of ETSI ITS-G5 performance over an IPv6-based platform. - In: 2022 IEEE International Performance, Computing, and Communications Conference (IPCCC), (2022), S. 185-193
Intelligent transport systems (ITS) promise to leverage wireless communications among vehicles. Performance of wireless communication is of crucial importance and can severely impact safety, efficiency and infotainment of transport applications. In this paper, in order to promote the usage of IPv6 in vehicular networks, we deploy a wireless communication framework in a Linux environment based on the Internet protocol (IP). Further, we evaluate the behaviour of the ITS-G5 in various stationary and mobile scenarios to investigate the impact of environmental and radio factors on the performance of ITS-G5. Several measurements such as inter-reception time (IRT), packet loss, latency, end-to-end (E2E) latency, reception position error (RPE), and throughput are carried out to discover the limitations and strength of the technology in a real world test-bed.

Distributed vehicular communication protocols for autonomous intersection management. - In: The 13th International Conference on Ambient Systems, Networks and Technologies (ANT) / The 5th International Conference on Emerging Data and Industry 4.0 (EDI40), (2022), S. 150-157
Intersections are considered to be a vital part of urban transportation and drivers are prone to make more mistakes, when driving through the intersections. A high percentage of the total fatal car accidents leading to injuries are reported within intersections annually. On the other side, there usually is traffic congestion at intersections during busy times of day. Stopping the vehicles in one direction to let the vehicle pass in the other directions leads to this phenomenon and it has a huge effect on traffic delay, which causes great squander in natural and human resources as well as leading to weather pollution in metropolises. The goal of this paper is to design and simulate different spatio-temporal-based algorithms for autonomous connected vehicles to be able to cross the intersection safely and efficiently. Vehicles employ vehicle-to-vehicle (V2V) communication via dedicated short range communications (DSRC) [4, 1] to exchange their kinematic information with each other. The proposed algorithms are compared to each other as well as with traditional methods like traffic lights in terms of various performance metrics such as traffic congestion, speed and especially delay to find the optimal control approach for autonomous intersection management.

Safety-centric vehicle classification using vehicular networks. - In: The 18th International Conference on Mobile Systems and Pervasive Computing (MobiSPC), the 16th International Conference on Future Networks and Communications (FNC), the 11th International Conference on Sustainable Energy Information Technology, (2021), S. 238-245
This paper investigates the vehicle classification (VC) based on vehicular ad-hoc networks (VANETs). Using VANETs, one can extract the physical and mobility characteristics of the vehicles globally and in a real-time manner. In this paper, we propose an in-depth novel safety-driven VC method for heterogeneous connected vehicles. In this innovative approach, road vehicles are classified into a broad range of classes according to their distinctive behaviors and safety measures. The proposed method can play a vital role in reducing collisions and can be used as a safety standard reference in VANETs-based VC systems. Furthermore, advance driver assistance systems (ADAS) can integrate this method and extend road safety by notifying vehicles of dangerous situations on the road using V2X communication.

Modeling and evaluation of the impact of motorcycles mobility on vehicular traffic. - In: Journal of Transportation Technologies, ISSN 2160-0481, Bd. 11 (2021), 3, S. 426-435
Traffic simulation can help to evaluate the impact of different mobility behaviors on the traffic flow from safety, efficiency, and environmental views. The objective of this paper is to extend the SUMO (Simulation of Urban Mobility) road traffic simulator to model and evaluate the impact of motorcycles mobility on vehicular traffic. First, we go through diverse mobility aspects and models for motorcycles in SUMO. Later, we opt for the most suitable mobility models of motorcycles. Finally, the impact of motorcycle mobility on different kinds of vehicles is investigated in terms of environment, fuel consumption, velocity and travel time. The result of modeling and evaluation shows that based on the mobility model of the motorcycle, vehicular traffic flow can be enhanced or deteriorated.
