Although significant progress has been made in the last few years towards cooperative and autonomous driving, the transition from human-driven to fully automated vehicles is expected to happen slowly. The question of semi-autonomous driving, where Advanced Driver Assistance Systems assist human drivers in their decisions, will therefore become increasingly important. In this paper, we consider the...
Whatever type of distraction during the driving of a vehicle can compromise the safety of not the driver, but also of all drivers present on the highway. Using the mobile while driving is the greatest examples of this problem at a global level. In this regard, a system that helps the driver improve and keep up the attention on the road, could be a solution. This paper proposes a cooperative assistance...
Automotive safety validation requires evaluation on a statistically representative set of roadway configurations and scene geometries. Scenes must be sampled from a statistical model representative of what actually occurs on roadways. This paper introduces a methodology for realistic scene model construction based on factor graphs that can be applied to arbitrary road geometries. Parameter learning...
A good level of situation awareness is critical for vehicle lane change decision making. In this paper, a Data-Driven Situation Awareness (DDSA) algorithm is proposed for vehicle environment perception and projection using machine learning algorithms in conjunction with the concept of multiple models. Firstly, unsupervised learning (i.e., Fuzzy C-Mean Clustering (FCM)) is drawn to categorize the drivers'...
This paper suggests a concept for motivating driver cooperation. The proposed interaction concept incorporates gamification to motivate cooperation in a lane-change scenario in a highly automated environment. Prior research has shown that without taking individual factors such as time pressure or social status into account, cooperation-acceptance rates were as high as 88% for the left-lane and 100%...
Vehicles equipped with varying levels of automation and connection are starting to share the road with conventional vehicles. This provides new opportunities to design and test systems to control the acceleration dynamics of those equipped vehicles in mixed traffic environment contexts, with the global aim to globally reduce traffic congestion and increase traffic safety. Recent work has been focusing...
In Vehicular Ad Hoc Networks (VANETs), efficient use of the control channel affects both safety applications that use the control channel and other applications that use the service channels. Its efficiency deteriorates due the collisions on accessing to the control channel or due to the merging collisions which happen when fast moving vehicles use the same allocated channels. In this paper, we propose...
Electrified agricultural machinery offers enormous potential to use resources more efficient. Whereas energy storage in batteries limits period of use, a power supply by cable promises an interesting alternative for systems with a bounded operational area. Hence a novel concept for MVDC power transmission in such a mobile application is presented. The goal is a rated power of 300kW. This article focuses...
Several Intelligent Transportation Systems (ITS) rely on localization to enable services ranging from comfort to safety applications. Following this same idea, the use of Dedicated Short Range Communications (DSRC) devices based on the IEEE 802.11p standard, and the Vehicular Ad Hoc Networks (VANETs) paradigm, have resulted in the deployment of several protocols, services and applications that need...
Potential disruption stemming from self-driving vehicle (SDV) technology may change not just vehicles, but the foundations of our mobilities. As an example of analysing SDV technological development, this paper focuses on SDV intersection control. The starting premise is that technological development requires an understanding of previous developmental trajectories and potential future needs, rather...
Real-time video analysis at the edge of the network is very promising to significantly improve public safety, e.g., dangerous accidents detection and find a missing person. Simply uploading the video stream to the cloud for analysis costs too much energy and network bandwidth to an energy-limited camera. Hence we propose EVAPS (Edge Video Analysis for Public Safety), which distributes the computing...
In this paper, we will introduce the necessity of real-time safety monitoring system for high-speed railway vehicle and propose a new type of safety monitoring system using a low-power wireless connection. To verify the proposed safety monitoring system is feasible, we measure the packet error rate on the moving train and show the analyzed results.
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...
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,...
Vehicular Ad-hoc Networks (VANETs) using a connected-car technology can support safety-critical applications in Cooperative Intelligent Transportation Systems (C-ITS). While WAVE/DSRC has been investigated by a number of researchers to support VANETs, it may not be easy to distribute WAVE/DSRC in the near future due to several practical obstacles. In this paper, we discuss an alternative to support...
In this paper, we describe an VM2M overlay architecture where the overlay acts as the control channel (CCH) of VANET to transfer safety messages between vehicles and RSU. The VM2M overlay network is implemented over dedicated preamble codes in the physical layer and the medium access control (MAC) layer modeled as the IEEE 802.15.4 carrier sense multiple access (CSMA/CA) mechanism. In this paper,...
In vehicular ad-hoc network (VANET), safety applications require the dissemination of safety information and vehicular states to all nearby vehicles through broadcasting. However, due to the tremendous information, broadcast channel will be confronted with great pressure. Therefore, vehicles should adjust their contention window to avoid intense competition on channel. In this paper, we propose a...
Road networks are the most important facility to the public transportation in modern cities. Governments around the world allocate large amounts of budgets for the pavement maintenance every year. In this paper, we proposed a crowdsourcing solution to categorize road anomalies into safety related anomalies such as speed bumps and rumble strips, and dangerous anomalies such as bumps and potholes. The...

Intelligent Transportation System (ITS), the safety-related message is propagated based on the wireless communications through vehicle to vehicle (V2V) and vehicle to infrastructures (V2I) in vehicular Ad hoc networks (VANETs) environments. Hence, the network connectivity is a key requirement for successfully safety-related message propagation. In this paper, we analyze the influence of vehicle density...
