The system is part of a larger traffic decision support system (TDSS) that can assist the operators of traffic control centers when they have to reduce non-recurrent congestion using a network-wide approach. The kernel of the system is a fuzzy case base that is constructed using simulated scenarios. By using the case base and fuzzy interpolation the decision support system generates a ranked list of combinations of traffic control measures. The best combinations can then be examined in more detail by other modules of the TDSS that evaluate or predict their performance using macroscopic or microscopic traffic simulation. At a later stage the fuzzy decision system will be complemented with an adaptive learning feature and with a set of fuzzy rules that incorporate heuristic knowledge of experienced traffic operators.","PeriodicalId":173372,"journal":{"name":"ITSC 2001. 2001 IEEE Intelligent Transportation Systems.

In this so called \"algorithmic system\" the number of functional components, as well as the features describing the current traffic scene, can be easily expanded or changed. Existing algorithms can be integrated into the algorithmic system without an expense. Due to the implementation of the algorithmic system in ANSI C, the OSEK conformity and the strict separation from the measurement, test and simulation environment, the source code can be easily ported to a control system hardware. The paper describes in detail the structure of the algorithmic system, its different elements, processes and the vehicle integration during different phases of development. The last section shows the advantages of this approach in the prototype developments of a \"radar camera ACC\" and a \"lane keeping support\".","PeriodicalId":173372,"journal":{"name":"ITSC 2001. 2001 IEEE Intelligent Transportation Systems.

From the perspective of stability, CTH schemes can be implemented autonomously while guaranteeing that errors in spacing do not amplify during any maneuver of the lead vehicle in the string. The corresponding control efforts of following vehicles are filtered versions of their immediately preceding vehicles. The primary benefit of ACC systems in terms of relieving congestion is the improvement of throughput; however, this will require a reliable distance regulation at traffic capacity.","PeriodicalId":173372,"journal":{"name":"ITSC 2001. 2001 IEEE Intelligent Transportation Systems.

ECDIS-the intelligent heart of the hazard and collision avoidance system ecdis——危险和碰撞避免系统的智能核心

Only the Electronic Chart Display and Information System (ECDIS) can fulfill the requirements of HACAS effectively. It can display charts and navigational information, radar/ARPA and AIS data. Additional data and information can be incorporated as required making ECDIS the most comprehensive safety device on a ship's bridge. ECDIS is regarded as the navigational and anti-grounding tool of a ship. However, its safety features are much more sophisticated and it should be regarded as the main safety tool onboard a vessel. In addition to displaying data from various sources and providing navigational tools, ECDIS can be considered an expert system capable of providing solutions to navigational and safety problems, and of automatic application of safety or emergency procedures. The new functionalities of dynamic depth and voice output will enhance further the safety value of ECDIS. Both these functionalities are already available and presented in this paper. Another important application of ECDIS as a hazard and collision avoidance tool is on the pleasure craft. Not many of these carry radar, and frequently have no room for additional dedicated displays. However ECDIS and its non-official counterpart, ECS (Electronic Chart Systems), are becoming prevalent on small vessels and will be the best means to display AIS and dynamic depth data. This will result in a considerable improvement in safety for small craft. Most of the modern navigational packages for the pleasure market provide all the important functionalities used by the commercial shipping, one of them comes already with voice output.","PeriodicalId":173372,"journal":{"name":"ITSC 2001. 2001 IEEE Intelligent Transportation Systems.

The adopted methodology foresees the use of three different algorithmic structures; the first one is able to define the dynamics of the transportation system, and has gotten with a macro model of traffic simulation; the second is used for estimating the travel times on the links, using Gallager's algorithm (1977), and the third defines the resolution of a linear problem of optimization subject to non linear constraints.","PeriodicalId":173372,"journal":{"name":"ITSC 2001. 2001 IEEE Intelligent Transportation Systems.
