Safety

We propose a hybrid ITS safety architecture that combines vehicle-to-vehicle communication and
vehicle-to-roadside sensor communication. Opposed to dedicated roadside units, which require major investments for purchase, installation and maintenance, roadside wireless sensor and networking technology represents a cost-effective solution and can leverage the deployment of the system as a whole. Among the various services of the hybrid communication system, the paper introduces accident prevention and post-accident investigation. We present a system and protocol architecture with a fully distributed concept for efficient and secure storage of sensor data. For deployment, this architecture will likely be combined with an alternative approach using dedicated road-side units as a centralized network element for communication and data storage. For the proposed system, we describe the main components (radio, networking and services, security). Finally, we describe our prototype implementation and experimental testbed featuring hardware and software platforms for vehicle on-board units and sensor nodes.

In this paper, we propose a detection method to avoid collision between a vehicle and a
motorcycle in a road intersection using radio wave DOA estimation by ESPRIT. Our system is
based on distributed system and requires no infrastructures on the road side. We presume to
install the transmitter in the motorcycle and the receiver in the vehicle. The vehicle receives
the radio waves arriving from different directions due to reflections from buildings and
diffraction around the corner of building. By Direction of Arrival Estimation, the receiver is
gripped the basic characteristic of the propagation of the radio wave. The results made
possible the calculation of whether the motorcycle is in Line of Sight (LOS) or Non Line of
Sight (NLOS), and right or left of the vehicle.

This paper analyses typical intersection scenarios with respect to the feasibility of
motorbike-based warning or automatically intervening assistance systems to protect the
motorbike driver from dangerous situations induced by surrounding car drivers. Based on
accident statistics, typical crash scenarios have been identified. The trajectories of the
involved vehicles have been modelled realistically, and the resulting scenarios have been
analyzed in a simulation environment with respect to a variety of parameters. The potential
of motorbike-based assistance systems is assessed, and sensor and environment perception
requirements are derived.

During the last decade, the European Commission focuses on the enhancement of road safety through the implementation of ITS. These new technologies have been already introduced in the automotive market and their evolution is definitely fast and efficient. However, the application of such technologies in powered-two-wheelers, in order to increase the safety and comfort of riders, is currently lacking behind. Motorcycle and moped fatalities account for 17,8% of the total number of road accident fatalities in Europe. This paper presents the SAFERIDER project aim and developments towards the enhancement of PTW riders’ safety by applying in-vehicle ITS on PTWs of all types for the most crucial functionalities.

Motorcycle riding is an increasingly popular mode of transportation in the United States,
particularly among riders 40 years and older. Associated with the increased number of
motorcycle sales and registrations, unfortunately, is the number of annual fatalities and
injuries among motorcyclists (doubling since 1997 to 4,810 in 2006). This increase in
motorcyclist fatalities contrasts with the steady progress in reducing annual fatalities
involving passenger vehicles. This paper proposes that technologies from Intelligent
Transportation Systems (ITS) have the potential to reduce the risk of motorcycle riding and
help reverse the trend in motorcyclist fatalities. Up to this point, ITS countermeasures have
not yet been fully realized for motorcycles, but they show promise for improving safety. To
maximize the potential of ITS contributions, it is critical to recognize the unique
characteristics of motorcycles as a vehicle class in terms of ITS system architectures and
implementation. This paper intends to showcase key opportunities for the adaptation of ITS
technologies for making motorcycle driving safer.
