This paper presents a traffic monitoring application realized through Wireless Sensor Network (WSN) technology,
in particular the Telos platform, within SAFESPOT Project funded by the European Community. Aim of this project
is providing a flexible, low-cost and low-maintenance wireless solution for obtaining traffic-related data that
can be used for automatically generating safety warnings at black spots along the road network. The WSN consists
of one Gateway Node (GN) and n Sensor Nodes (SNs) deployed along the roadside thus inducing an approximately
linear topology. By means of a serial interface, each SN integrates different types of sensors whose raw signals
are locally processed using simple specifically developed algorithms in order to derive traffic-related variables
such as vehicle detection, speed and direction. The WSN supports a bi-directional radio communication: through a
topology-oriented multi-hop routing protocol, the GN polls a desired SN which possibly replies to the command
(for instance, by transmitting the processed data). The GN stores data received from the many SNs and
periodically passes them to a Road Side Unit (RSU) where a more complex data processing is then carried out.

[abstract]
Accident black spots in urban areas are in particular the controlled and non-controlled intersections,
because the road users are often confronted here with complex situations that are sometimes hard to
interpret and to deal with properly. Therefore, intersection safety systems have a high potential to prevent
traffic accidents due to misjudgment and rule violation. The Intelligent Cooperative Intersection Safety
System (IRIS), as part of the European research project SAFESPOT, is a cooperative roadside application that
aims at decreasing the number of accidents at controlled intersections. Vehicle-to-infrastructure communication
and data fusion techniques make the core of the system. The presentation provides on overview on the concept,
achievements and demonstration plans of the IRIS.
- ITS Challenges: Standardization, Certification and Testing

[abstract]
ITS (Intelligent Transport System) world is evolving rapidly toward common communication architecture
for cooperative systems. Many European projects, such as SAFESPOT, CVIS, NoW, SEVECOM, are working very
efficiently in researching ITS areas (architecture, security, cooperative applications, communication, etc.)
and developing new and innovative technologies and ideas for being applied inside this promising world.
All these projects liaison and cooperate with ETSI, ISO, C2C-Consortium and COMeSafety in order to address
results and interests toward standardization efforts, and finally, to achieve a global and interoperable
ITS world. One of the key to get these challenges, and one of the main objectives of SAFESPOT, is to start
up the definition of an effective certification framework to ensure that cooperative systems, based on
vehicular communications are compliant to standards and to prove their interoperability. Finally, because
of ITS world covers a huge set of heterogeneous technologies, it is crucial to face the new challenges to
test all these technologies in order to get interoperability and good performance based on an innovative
and clear testing methodology which will be presented, as well as other raising testing challenges like
Field Trials which is considered as an important method of testing to be taken into account in ITS
environment.

Le 6ème Programme Cadre Européen pour la Recherche et le Développement regroupe un ensemble important de projets
qui ont pour objectif commun de réduire de moitié le nombre des accidents routiers d’ici à 2010. Dans ce papier,
nous présentons les projets CVIS, SAFESPOT, COOPERS et effectuons une synthèse comparative de différents
aspects: leurs consortiums, objectifs, innovations, technologies de communication et applications ; et nous
concluons sur leurs similitudes et différences. Puis nous présentons la participation de l’ASFA à ces
projets européens.
The 6th European Framework Program is promoting a huge portfolio of projects in order to achieve the challenging
goal to halve the number of road accident by 2010. In this paper, we present the three projects SAFESPOT,
CVIS and COOPERS and provide a comparative synthesis on different aspects: their consortium, objectives,
communication technologies and applications; and we conclude on their similarities and differences. Then
we present the French Motorway Association (ASFA) participation to those projects.

[abstract]
In the integrated research project SAFESPOT the concept of a Cooperative Pre-Data- Fusion has been implemented
as a novel approach for an environmental perception system. This paper describes the approach of fusing
Laserscanner data with detailed digital map data. It is being developed in the subproject SAFEPROBE which
specifies and develops an in-vehicle sensing platform.
- Driving Simulator Study to support the Design of an Intersection Safety Application

Abstract: The aim of the SAFESPOT IP is to prevent road accidents by developing a Safety Margin Assistant
that extends the drivers´ awareness in space and time. One SAFESPOT application is the Intelligent
Cooperative Intersection Safety system (IRIS). In order to gain knowledge about the interaction with the
driver, a driving-simulator experiment was performed. The objective was to support the design activities
and assess the application concept. Examined scenarios included a warning for a passenger or police car
that violated the red light and a warning for a conflict with a scooter, with different warning timings and
approaching velocities. The study showed that the safety margin increased when the driver was warned earlier,
that the participants preferred an early above a late warning, and a passenger car was experienced as more
critical than a police car when both drove 60 km/h. Furthermore, the experienced warning time for the police
car came later than for the normal car when they both drove 30 km/h. This implies that for the final application
the warning for a police car could be given earlier than for a passenger car. Regarding the display, participants
had a look at the display in 74% of the critical situations, and participants indicated that they understood the
icon 'a little'. It is recommended to improve the provision of visual information. Overall, the driving
simulator experiment was useful in the early stage of specification and development of the application.
