- 3.8Contribution to Programme/Key Action Objectives
3.6Tests Results3.7Achievements and RisksDenseTraffic has been a very successful project which attained the goals set at its beginning. During the course of the development several innovations and engineering breakthroughs beyond the initial goals have also been obtained. Some of these innovations have been concentrated in a patent that has already been filed. Among the benefits obtained from DenseTraffic we can enumerate the following:
We should also mention the main risks that face the introduction of more performing FLR sensors. These risks are:
The two first risk factors to the successful introduction of the technologies developed in DenseTraffic have to be treated at a higher level in which the public has to become aware of the advantages of ACC systems and investments have to be made to fund the introduction of the massive low cost systems. The third risk factor is also related to the acceptance of the ACC system by the general public. This lowering of the probability of false alarm to the expected values is by no means a simple task. It is required that an extensive data collection, testing and algorithm refinement cycles should be done. It can be quoted that a first generation radar was tested over 1,000,000 km (several radars) until was qualified. The last risk factor can be addressed without performance reduction by further increasing the frequency to 150 GHz or even 300 GHz. 3.8Contribution to Programme/Key Action ObjectivesDENSETRAFFIC has been submitted to the IST 2000 program under Key Action 1 – Systems and Services for the Citizen, Action Line 1.5.2 Intelligent vehicle systems. The objectives of the project are the development of a computerized sensor system, eventually to be included in all vehicles that will reduce the rate of accidents on Europe’s roads, by automatically avoiding collisions. The DENSETRAFFIC consortium is made up of the European leaders in their fields of RF sensor technology, MMIC technology and vehicle systems integration, who will work together to develop a system that is affordable across the board, so that it can be integrated into the ordinary vehicles used by every citizen and not reserved for the luxury market. In addition, the system will become a seamless part of the vehicle’s operational system, so that its benefits will be reaped by anyone licensed to drive a vehicle. Although initial testing of the system is planned for trucks, where collisions result in the greatest consequences, it will eventually be tested in cars and other vehicles. The project objectives are relevant to this area whose main aim is the increase of the “intelligent assistance and user-friendliness” in the next generation of vehicles by bringing Adaptive Cruise Control systems closer to being true automatic collision avoidance systems. KA 1 aims to foster the creation of the next generation of user-friendly, dependable, cost effective and interoperable general-interest services. The proposed system will contribute to the safety, security, comfort and efficiency of citizens using embedded technologies in road transport systems by increasing the reliability of current ACC systems. It will accomplish this by developing an innovative technology to increase the monitored coverage of the area immediately in front of the vehicle to prevent collisions, as well as addressing unforeseen situations caused by vehicles cutting in to the monitored area and in stop&go traffic. IST 1.5 Transport and Tourism – Widespread acceptance of the proposed system will be incorporated into industrial consensus on common specifications for vehicle safety as well as enhancing the safety standards for collision avoidance devices. IST 2000 1.5.2 Intelligent vehicle systems. The system aims to advance ACC systems to true collision avoidance by including automatic emergency braking capabilities, possible because of the improved monitoring of the road situation in front of the vehicle. By being completely integrated into the vehicle’s control system, the DENSETRAFFIC system also addresses the issue of user-friendliness, implying the building and deployment of interaction modes that are “relaxing” and “enjoyable” for the citizen, and do not involve a steep learning curve. This includes trust and confidence in the technology. The system will be incorporated into in-vehicle platforms for automated driving systems and will be developed using low-cost components that will allow inclusion of the system in trucks and vehicles accessible to all citizens. In order to increase the dependability of the system, a self-test system will check whether the radar sensor antenna aperture is covered with mud or snow. Driver warning systems will alert the driver to the possibility of a collision and to the obstruction of the sensor. The IST vision is expected to catalyse an expanse of business opportunities arising from the aggregation of added value services and products. Services can be provided by physical agents (e.g. cars). Inclusion of the system into European vehicles will give them a competitive edge over imports, especially from Japan, where ACC technology development is advancing rapidly, increasing their sales potential. This proposal addresses the following Key Enabling Technologies identified by ISTAG: Embedded intelligence; Micro and opto-electronics; Trust and confidence enabling tools.
