Abstract

The present invention relates to a traffic condition information providing system and method for transmitting traffic condition occurrence information through a wireless call network, and processing real-time traffic condition occurrence information on a road collected and processed through various routes into a traffic information data format. In order to provide a traffic condition information providing system and method for transmitting traffic information through a wireless paging system and displaying traffic condition occurrence information along with a digital road network map to a traffic information terminal having wireless calling data reception and digital road network information processing capability, Traffic information collecting means (11) for collecting situation occurrence information; A traffic information host computer 12 for converting to a traffic information data format; A traffic information server 13 for converting to a traffic information block; A radio call network 14 for propagating a traffic information block to the air; And a traffic information terminal 15 for expressing the traffic information block on a digital road network, wherein the method is applied to the traffic condition information providing system, the first step of collecting and storing traffic condition occurrence information (501 to 503). A second step (504 to 506) of processing and outputting the traffic information block; A third step (507) of broadcasting using the wireless call network (14); And a fourth step (508 to 510) of receiving and decoding the traffic information block and displaying it on the digital road network, thereby reducing traffic congestion at a low cost and allowing the driver to drive comfortably.

Claims (7)

Traffic information collecting means (11) for collecting and outputting traffic situation occurrence information; A traffic information host computer 12 which receives traffic situation occurrence information from the traffic information collecting means 11, converts the traffic situation occurrence information into a traffic information data format, and outputs the traffic information; A traffic information server 13 which receives a traffic information data format from the traffic information host computer 12 and converts the traffic information data format into a traffic information block; A wireless call network 14 which receives a traffic information block from the traffic information server 13 and converts the traffic information block into a radio call signal form and propagates to the air; And a traffic information terminal 15 which receives the traffic information block propagated by the radio call network 14 and expresses it on a digital road network stored in a database and outputs it to a user. system. Traffic information collecting means (11) for collecting and outputting traffic situation occurrence information; A traffic information host computer 12 which receives traffic situation occurrence information from the traffic information collecting means 11, converts the traffic situation occurrence information into a traffic information data format, and outputs the traffic information; A traffic information server 13 which receives a traffic information data format from the traffic information host computer 12 and converts the traffic information data format into a traffic information block; A wireless call network 14 which receives a traffic information block from the traffic information server 13 and converts the traffic information block into a radio call signal form and propagates to the air; And a traffic information terminal 15 which receives the traffic information block propagated by the radio call network 14 and expresses it on a digital road network stored in a database and outputs it to a user. In the method, the traffic situation occurrence information collected through the traffic information collecting means 11 is input to the traffic information host computer 12, converted, and then stored and updated in a first traffic information database, and then periodically A first step (501 to 503) which is accessed and is output to the traffic information server (13); The traffic situation occurrence information input to the traffic information server 13 is stored and updated in a second traffic information database, and then periodically accessed and processed into a traffic information block to be transmitted to the radio call network 14. Steps 504-506; A third step 507 in which the traffic information block received by the radio call network 14 is converted into radio call transmission formats (POCSAG, FLEX, etc.) and FSK (Frequency Shift Keying) radio signals to be broadcasted in the air. ; And the traffic information terminal 15 receives and decodes the traffic information block broadcasted through the radio call network 14, stores the data in a third traffic information database, updates it, and displays it on the digital road network to the user. And outputting a fourth step (508 to 510). The method of claim 2, wherein the converting of the traffic situation occurrence information of the first step (501 to 503), traffic representing a particular point selected on the road to indicate a major intersection or road section on the road And traffic situation occurrence information is converted into a unique number of a traffic link (102) representing a road segment (segment) between the node (101) and one traffic node and a neighboring traffic node. The process of claim 3, wherein the process of converting the traffic situation occurrence information into a unique number of the traffic node 101 comprises: a unique start node number 201 at which the traffic situation starts and a unique end node number (203) at the end of the traffic situation. And converting into unique number sets of intermediate nodes existing in the middle of the start / end node section. The process of claim 3, wherein the process of converting the traffic situation occurrence information into the unique number of the traffic link 102 comprises: identifying the unique number 301 of the traffic link corresponding to the traffic redemption occurrence section and the traffic redemption generation direction on the link. Traffic state information providing method, characterized in that the conversion to a combination of the direction number (302) to display. According to claim 3, The process of converting the traffic situation occurrence information into the unique number of the traffic link 102, the traffic corresponding to the traffic situation occurrence section in consideration of the traffic situation occurrence direction (vehicle progress direction) in the round trip lane section Traffic situation information providing method characterized in that the conversion to the unique number (303) of the link. The traffic information block providing method according to claim 2, wherein the traffic information blocks of the second steps (504 to 506) are constituted by a set of traffic information cells (402) representing traffic conditions of a predetermined section. ※ Note; Disclosure based on original application.
