Facing various uncertainties in real world traffic, navigation services are typically formulated as a certain stochastic shortest path problem (SSPP). In the past several years, many stochastic objectives in SSPP has been proposed, among which maximizing the probability of arrival on time draws certain attentions from researchers as it takes, besides absolute travel time, an extra dimension of information...
Many network-wide traffic management strategies based on the Macroscopic or Network Fundamental Diagram (NFD) have been developed in recent years. In this paper we investigate one of these strategies, namely feedback NFD-based perimeter control, which limits the rate at which vehicles are allowed to enter an urban region. The inflow limitation is imposed at selected main entry links (gated links)...
Transit signal priority (TSP) is a cost-effective way to improve transit system punctuality and efficiency. Connected Vehicle environment can provide precise and detailed information on vehicle movements, which is essential for effective TSP operation. This paper presents an integrated control strategy of TSP and speed guidance under the environment of Connected Vehicles. The strategy targets on buses...
This paper presents a novel vehicle platoon control algorithm using Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) wireless communications between platoon members. A platoon forms a chain of vehicles (e.g., trucks) for improved traffic and fuel efficiency. Platooning algorithms aim to maintain small inter-vehicular distance between vehicles under dynamic driving conditions like acceleration...
Environment perception is one of the most important tasks for Advanced Driver Assistance Systems and Automated Driving. Various types of sensors are used concurrently and fused into a consistent representation of the vehicle's surrounding. With more than one device involved, timing behavior becomes a relevant aspect of such systems. Delays due to processing and transferring data need to be considered...
In this paper, we present a realization of bid-based control strategy in which all drivers are modeled as passive players, and movement managers develop bidding strategies based on state-observer system principles. Their bidding strategies blend engineering attributes (length of dynamic queue, and number of turns since last win, which is analogous to delay) with economic attributes (the account balances...
Vehicular Ad-Hoc Network, or VANET is a computerized system which provides communications for a group of vehicles between each other and with equipments installed on the road side (RSU) or with camera mounted on the traffic light poles or, even with sophisticated sensors. In this paper we propose a new model of cluster formation based on beacon delay for real scenarios in VANET. Our approach is fully...
Internet of Vehicles (IoV) is an important constituent of next generation smart cities that enables city wide connectivity of vehicles for traffic management applications. A secure and reliable communications is an important ingredient of safety applications in IoV. While the use of a more robust security algorithm makes communications for safety applications secure, it could reduce application QoS...
According to the Convergence of a vehicle and IT, In-Vehicle-Network (IVN) is complicated and the multimedia data is increased. Ethernet guarantees Quality of Service (Qos) of the existing Control Area Network (CAN) communication and has a high bandwidth. As a result, the Ethernet is recently developed a new standard. IEEE 802.1 Audio Video Bridging (AVB) supports to handle priority and queuing for...
Ethernet Audio/Video Bridging (AVB) is promising technology in vehicle network (IVN) since it guarantees quality of service (QoS) for various traffics. Currently, new standards that added the control traffic have been developed by IEEE 802.1 Time Sensitive Network (TSN). In TSN, the performance of AVB is deteriorated due to the control traffic. To overcome this, frame is preempted that is specified...
Most of the ITS applications dedicated to vehicular networks rely on periodic messages sent in the vicinity of the vehicles. To ensure the road safety, the inter-messages delay admits strong constraints. The current standard proposes to adapt the inter-messages delay according to the vehicle dynamics. Nevertheless, when the density of vehicles is large, short delays may lead to collisions and losses,...
Recent works on enhancing comfortability and convenience in vehicles reveal that information collections by various wireless sensor nodes have the potential due to their easiness of install and their small size. However, the conventional wireless network standards achieve insufficient reliability for practical in-vehicle communications. In this paper, through implementing 2.4GHz devices in an actual...
The paper presents a start-up study and tests regarding the possibility of employing ZigBee communications for vehicle-to-infrastructure (V2I) communications. Such communications require less energy consumption, compared to other technologies and are recommended for dense urban areas, where the density of infrastructure equipment reaches higher levels and involves significant power consumption. A...
This study introduces the behavior of human driver's delay in model checking to verify the interaction between a driver and an automated driving system (ADS). An ADS interacts with humans, including other drivers and pedestrians to ensure safety on roads. In particular, human drivers and Level 3 ADSs must take control of the vehicle when the safety may be compromised. Since human driver behavior is...
The VANET (Vehicular Ad hoc Network) is a collection of mobile nodes forming a temporary network on variable topology, operating without base station and without centralized administration. The characteristics of VANET network that distinguishes it from other ad hoc networks, such as high mobility and communication with the infrastructure to support security or comfort applications, have prompted...
In the development of advanced driver-assist systems (ADAS) for lane-keeping, one important design objective is to appropriately share the steering control with the driver. Hence, the steering behavior of the driver must be well known beforehand. This paper adopts the well-known two-point visual driver model to characterize the steering behavior of the driver, and conducts a series of field tests...
Intelligent Transportation System (ITS) applications for integral and cooperative vehicle safety as well as some Advanced Driver Assistance Systems (ADASs) benefit from highly accurate positioning. Shared position data between dynamic traffic objects via Inter-Vehicle Communication (IVC) are the backbone for deriving vehicle trajectories. These can be used for assessing a situation's criticality in...
Numerous efforts are currently under progress to enhance the safety and efficiency of vehicular traffic through intelligent transportation systems. In addition, the growing demand for access to data and information from human users on the go has created the need for advanced vehicle-to-vehicle and vehicle to roadside communication systems capable of high data rates and amenable to high degrees of...
Always keeping a certain distance between vehicles in a platoon is important for collision avoidance. Centralized platoon systems let the leader vehicle determine and notify the velocities of all the vehicles in the platoon. Unfortunately, such a centralized method generates high packet drop rate and communication delay due to the leader vehicle's limited communication capability. Therefore, we propose...
In an energy harvesting vehicular network, efficient file transfer between two charging stations is challenging due to the lack of communication infrastructure. Naturally, a source station can allocate the packets to a set of vehicles, which serve as relays to opportunistically deliver these packets to the destination station while performing their own tasks. In this paper, we show that, with packet-level...
