TÓM TẮT
In this research, a smart transportation system integrated with a management system of highly distributed communications network for personal rapid transit (PRT) was designed. The Personal Rapid Transit (PRT) system is a new and easy-to-use transportation solution for 1-4 persons to destination directly. PRT system offers great potential for becoming a common transportation system in the future involving driverless vehicles, ride comfort or collision warning. These advantages are low construction cost and operation cost. In PRT system, two well-developped significant procedures are automatic driverless control and crossway merging control. A safe and smooth operation management of merging in automated vehicle systems for PRT is run by a merging management system. Our work investigated this new merging management system related to a distributed traffic control, new locating method and safe dynamic headway. In this system, an efficient car communication bases on the vehicle-to-vehicle wireless protocol(V2V) and highly distributed control. In order to determine the car location, RFID technique is used. A new buffer-zone strategy and fuzzy logic control are two efficient vehicle-merging algorithms that are required for dynamic determination of the merging sequence for all cars in a Y-intersection. From simulation, it was found that cruise distance can be safely kept from each car to its front car and each car can merge into mainline gently and efficiently. An experiement with 5 toy cars in a Y-route was carried out, so the effectiveness of this new merging management system can be proved convincingly. Keywords—Merging Management; Merging Control; PRT.
