ITST 2005 offers each participant the possibility to take part in real-size demonstrations of embedded telecommunications systems.
Onboard demonstrations in real traffic conditions on the roads in Brest
- inter-vehicle communications (ad-hoc networks) - Oki
- on board digital terrestrial broadcasting - Antennessa/Dibcom
- adaptive cruise control radars - Autocruise / Volkswagen
1) Inter-vehicle communications (ad-hoc networks) involving 4 vehicles driving at 30-40 km/h (OKI Electric Industry Co - ITS Department - Yokosuka )
- Demo 1 "Info-entertainment" application between 2 vehicles:
transmission/reception of images and sound picked up inside the passenger compartment between 2 vehicles driving 20-50 meters apart
- Demo 2 "Comfort and safety" application involving 4 vehicles:
video recording of traffic conditions ahead of a vehicle (e .g. a road accident), filmed through the front windscreen and transmitted to 2 other vehicles located 400-500 meters away from the first one, via "hopping" from a fourth vehicle located between them.
30 min onboard demonstration
2) Onboard digital terrestrial broadcasting (Antennessa / Dibcom)
Moving vehicle equipped with:
- screens and loudspeakers for DVB-T (digital video broadcasting terrestrial) signals
- diversity antennas enabling the quality of the received signal to be improved
- a 2-access decoder enabling rapid estimation of the transmission channel and the correction of the Doppler effect generated by a vehicle moving at great speed, for 64 QAM coding
The technology linked with signal reception is implemented by the companies Antennessa (antennas) and Dibcom (decoders).
20 min onboard demonstration
3) Driving demonstrations with adaptive cruise control radar (Autocruise / Man / Volkswagen)
A Volkswagen Phaeton and a MAN truck equipped with Autocruise ACC radar. This system ensures the security distance between vehicles, according to local traffic conditions.The MAN truck is also equipped with the Lane Guard System (LGS) and the Electronic Stability Control (ESP).
30 min onboard demonstration
4) Demonstration of driverless vehicles (INRIA)
The demonstration will take place outside, near the Congress Center. Three vehicles, one Twingo and two INRIA cyber-cars, drive along by using the GPS information received by the vehicles' navigation system.
More precise navigation is made possible thanks to computer vision: the vehicles are equipped with video cameras and the images are processed in order to recognize pavements and buildings and so improve the vehicles' trajectory.
In this demonstration, two driverless vehicles follow one another: when the first vehicle detects a pedestrian, it decides to stop and sends this information to the vehicle behind it, enabling it to slow down too. This practical application is an "ad-hoc network", implemented by Hitachi.
Demonstrations inside the Congress center:
- real-time activity management system for road transportation - Elo Systèmes
- interactive driving simulator – CERV
- managing the Brest city bus network– Kéolys / Amec-Spie
- etc.
1) Real-time activity management system for road transportation (ELO Systèmes)
The system demonstrated inside the congress center presents data relating to a fleet of real vehicles on the road:
- position of vehicles,
- route history and distances covered,
- drivers’ driving times, work and rest periods,
- technical information concerning the vehicle, (fuel consumption, engine speed, braking, gear shifts…)
- instructions from managers to drivers as a result of analyzing activities: delivery and vehicle loading instructions, recommended routes, etc.
The vehicles are equipped with the following devices:
- an electronic box for collecting chronotachygraph information,
- GPS giving the vehicle’s position,
- "driver’s" terminal,
- temperature sensors for traceability of the cold chain,
- GPRS modem to transmit vehicle information and technical data.
2) Road traffic and ITS equipment simulator AREVIROAD (CERV Brest)
This simulator is a Multi-Agent System that enables different equipment to be tested in saturated road traffic involving some fifty vehicles, each with its own behaviour.
It is designed so as to easily test the functionalities of ITS-dedicated equipment, embedded or not: telemeters, radar sensors, antennas, ad hoc networks, etc.
It also tests interactions with the environment: the vehicle and the other vehicles in the network, smart road markings, for example
The originality of this simulator mainly lies in the way that the road traffic is generated.
Modeled devices are embedded in vehicles controlled by virtual drivers, all parties having the capability of perceiving their environment and interacting with it. Thus a virtual driver will perceive a vehicle braking ahead and will adapt his driving accordingly.
3) Managing the Brest city bus network (Bibus / Kéolys / Amec-Spie)
Presentation of a system to help operations and for passenger information:
- Brest city bus network’s control post, transported to the congress center, cartography locating the buses actually on the road (over one hundred in the rush hour)
- information about buses being early/late, compared to the official timetable
- visualizing the instructions given to drivers
- passenger information points at the "Place de la Liberté " bus stops, indicating the waiting times for 6 bus routes
