Description

Public transportation system using DS system and its control method {COMMON VEHICLE SYSTEM USED DSRC AND CONTROL METHOD THEREOF}

The present invention relates to a public transportation system using a DSRC system and a control method thereof, and more particularly, a DSRC system that provides an ITS service by performing packet communication at high speed within a short time within a small communication distance of less than 100 m while a vehicle is driving. Public transportation information using public transportation information, public transportation management, scheduled arrival time for bus arrivals, and optimal dispatch information for real-time dispatch, by providing appropriate management plans to support efficient vehicle operation. It relates to a system and a control method thereof.

Recently, due to the popularization of automobiles accelerated since the 1990s, side effects such as traffic congestion, casualties due to accidents, and air pollution have emerged as serious social problems. The economic losses due to traffic congestion exceeded 10 trillion won annually and are expected to reach 20 trillion won in 2000. Logistics costs due to traffic congestion amount to 15% of GNP. In addition, human and material damages caused by traffic accidents amount to KRW 8 trillion every year.

It is necessary to introduce the Intelligent Transportation System (ITS) system to solve such traffic congestion and human and material damages. The ITS system can alleviate congestion on the road by providing vehicle drivers with traffic congestion, bypass information and traffic information in real time. This ITS system is characterized by the use of complex technologies such as communication and information technology, sensor technology, control technology, antenna technology, and the ITS structure is defined at the national level, so that the overall efficiency is maximized by interworking with each other organically. Should be designed to ITS The services provided by the system are expected to be various services such as Electronic Toll Collection (ETC) service, Route Guidance service, and traffic information service.

However, since the ITS system has not been incorporated into public transportation, it is impossible to adjust irregular bus arrival times and dispatch intervals, and it is not possible to provide various information to the users so that the users have to take the inconvenience. There was this.

Therefore, the present invention is to solve the above-mentioned conventional problems, the purpose of the use of the DSRC system that provides the ITS service, providing public transportation information, public transportation management, bus arrival scheduled time guidance and dispatch discovery optimal management The present invention provides a public transportation system and a control method using a DSRC system that supports efficient vehicle operation by providing information in real time and establishing an appropriate operation plan.

Features of the present invention for achieving the above object, OBE is usually mounted on public transport, such as a bus; Installed at horizontal intervals, such as signs at bus stops, LCD screens can be used to display information, and send and receive information to and from the OBE. Sending to RSE; An information center including a data processing device and a database for collecting, processing, and distributing information on traffic conditions and vehicle driving conditions from the RSE, and providing information to related government agencies and public transportation companies; Information provided by the information center Therefore, it consists of information terminal that provides general users with bus departure / arrival guidance, scheduled bus arrival time guidance, communication situation and accident guidance.

Another feature of the present invention, the OBE mounted on the moving bus and the RSE installed on the signs of each bus station periodically transmitting and receiving information such as the current position of the bus, the moving speed and the presence of an accident; The information received by the RSE is sent back to the information center to be collected and collected, processed and distributed to the data processing device and database by collecting information on traffic conditions and vehicle driving conditions, and related government agencies and public transportation companies. Providing information and the like; In the information center, general information is provided to the general users through the information terminals installed at stops, stations, terminals, etc. Retransmitting to the OBE as well; A real time operation management function for providing a general vehicle location, an accident vehicle location, a faulty DSRC location, a faulty bus-mounted vehicle location service in the information center; Statistical analysis function that manages legal violations, dispatch intervals, driving contents, passenger movement status, and provides DSRC bus on board management service; And beacon failure statistics, dedicated declaration statistics, bus-mounted failure statistics providing services provided by the DSRC bus loading equipment management function.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

First, in order to provide an ITS service, a broadband communication network such as a digital cellular communication network or a PCS communication network may be used. Such a communication network uses a circuit communication method and has a low data transmission rate, so it does not actually provide an ITS service. Negative efficiency and low service costs. In contrast, the DSRC (Dedicated Short Range Communication) communication system refers to a communication system that provides ITS service by performing packet communication at high speed within a short time within a short distance of less than 100m while the vehicle is driving. Such a DSRC system can accommodate most of the ITS services and has high-speed, reliable packet communication. Therefore, DSRC packet communication technology is an essential technology that must be studied to implement ITS system.

In this regard, the present applicant has disclosed a vehicle mounting device (hereinafter abbreviated as OBE) and a roadside terminal device (hereinafter referred to as OBE) applying a DSRC communication system in a "study on the development of an IST high-speed wireless packet communication system" published in December 1999.
