Problems solved by technology

However, since the equipment in the public transportation needs to calculate the estimated arrival time based on the traffic information received from the bus information server, it requires the equipment in the public transportation to have various functions, which will increase the The complexity of the device within the
Furthermore, the disadvantages of the prior art described above increase the cost of the system including the equipment within the public transport
Furthermore, since the information of the equipment stored in each public transportation vehicle needs to be revised every time the bus route changes, it is difficult to manage the equipment in the public transportation vehicle

Embodiment Construction

[0016] Other objects and aspects of the present invention will become apparent from the following description of preferred embodiments with reference to the accompanying drawings, which are set forth hereinafter.

[0017] figure 1 is a block diagram illustrating a system for providing information including an estimated time of arrival at a bus stop by using dedicated short-range communication in accordance with a preferred embodiment of the present invention.

[0018] refer to figure 1 , the system includes an electronic display device 10, a device 20 in a public vehicle, a plurality of base stations 30 R1 to R4 along the route, and a bus information server 40.

[0019] The electronic display device 10 is installed in the bus. The electronic display device 10 is mounted to the upper portion of the back of the driver's seat or to the ceiling in front of the passenger. The electronic display device 10 receives desired information including an estimated time of arrival from th...

Abstract

A method for providing an expected arrival time of bus stops or major bus stops to bus passengers is disclosed. The method includes the steps of: a) collecting traffic information including a on-board device ID, a roadside base station ID and a pass time from the roadside base station; b) computing an average traffic speed of each section based on the collected traffic information and computing time required for arriving to each bus stop from a roadside base station based on the computed average traffic speed of each section; and c) at the bus information server, transmitting the computed time required for arriving to each bus stop from the roadside base station in order to expected arrival time of each bus station and time required for arriving at each bus stop through a display device to passengers of a bus by using the roadside base station and on-board device.

Description

technical field [0001] The present invention relates to an Intelligent Transport System (ITS) using Dedicated Short Range Communications (DSRC); Desired information such as time, and a computer-readable recording medium for performing the above method. Background technique [0002] In general, dedicated short-range communication DSRC is two-way short-range communication between communication devices installed to various bus stops and public vehicles installed in buses. Hereinafter, a communication device installed at each bus stop is a bus stop base station, and a public transport communication device in a bus is an in-public transport device. DSRC was developed to automatically collect bus fares, and based on its high-speed two-way communication, it has been applied to various fields of Intelligent Transportation System (ITS). For example, an ITS using DSRC is used to collect traffic information of a road of interest and provide the collected traffic information to passen...
