Description

차량번호판 인식을 이용한 교통혼잡구간 혼잡통행료징수 및 부제위반차량 검출시스템{omitted}Traffic Congestion Toll Collection and Subtitle Violation Vehicle Detection System using License Plate Recognition {omitted}

본 발명은 신호교차로가 많은 특성상 중심시가지 혼잡구간의 시점부 및 종점부에 문형식을 이용한 차로별로 접촉식 검지기와 비접촉식 검지기를 설치함으로 중심시가지 신호교차로의 회전교통량과 유입교통량에 대응하여 혼잡통행료 징수와 부제위반차량을 검출할 수 있으며 교통량이 집중되는 첨두시간대에 무정차로 검출할 수 있으며, 요금징수시간대 설정 등으로 효과적인 기술적 통제수단이 확보 된다.According to the present invention, due to the large number of signal intersections, the contact and non-contact detectors using door type are installed at the start and end points of the congested section of the central urban area to collect congestion tolls and subtitles in response to the rotational traffic and inflow traffic of the central urban signal intersection. Violation vehicles can be detected, traffic can be detected at peak times when traffic is concentrated, and effective technical control measures can be secured by setting a toll collection time zone.

상습적으로 발생되는 혼잡구간에 차량번호판 인식을 이용하여 통행료를 자동 정산처리 하여 차량진입을 억제 또는 우회분산처리를 유도함으로 도로의 소통기능을 회복하고 승용차수요를 억제하는 효과가 매우 크고 도로변 교통유발시설물의 감시를 통하여 교통유발부담금을 징수를 위한 수단 확보도 가능하다It is very effective in restoring the traffic function and restraining the demand of passenger cars by restraining entry of vehicles or inducing diversification by automatic settlement processing of tolls by using license plate recognition in the congested sections. It is also possible to secure the means for collecting traffic incurred charges through monitoring

기존의 차량진행방향에 설치되는 접촉식 검지센서(루프검지기 등)를 이용한 번호판 인식카메라는 검지능력이 우수하나 접촉식 검지센서(루프검지기 등)가 도로공사, 차량통행으로, 동절기 노면의 팽창 등으로 자주 파손되어 유지관리에 문제점이 있다. 비접촉식 검지센서(영상검지기 등)를 이용한 번호판 인식카메라는 물리적인 도로공사, 차량통행 등에 영향을 받지 않아 유지관리에 매우 효과적이다.License plate recognition cameras using contact detection sensors (loop detectors, etc.) installed in the direction of the vehicle have excellent detection capabilities, but contact detection sensors (loop detectors, etc.) are used for road construction, vehicle traffic, and inflation of winter roads. Frequently broken, there is a problem in maintenance. License plate recognition cameras using non-contact detection sensors (image detectors, etc.) are very effective for maintenance because they are not affected by physical road construction or vehicle traffic.

중심시가지 특성상 신호교차로, 회전교통량, 유입교통량, 도로변 대형교통유발시설물 등이 위치하여 특정한 첨두시간대에 교통체증이 극심하여 심각한 사회적 교통 혼잡비용을 초래하고 있으며, 이것에 적절한 기술적 통제수단인 교통류관리 시스템이 없는 실정이다. 그러므로 상습적인 혼잡구간에 교통류관리를 위하여 중심시가지 특성에 효과적인 시스템이 필요하다.Due to the characteristics of the central city, traffic intersections, turning traffic, inflow traffic, and roadside traffic-causing facilities are located, resulting in severe traffic congestion costs in extreme peak hours, resulting in severe social traffic congestion costs. This situation is absent. Therefore, an effective system for the characteristics of the central city is needed for the management of traffic flow in the habitual congestion section.

기존의 통행료징수방식은 요금소를 차로별로 설치하여 정산처리 함으로 긴 대기행렬이 발생되고 중심시가지에 요금소를 설치할 공간이 현실적으로 어렵다.In the existing toll collection method, long waiting queues are generated by setting up tollgates by lanes and the space for installing tollgates in the central city is practically difficult.

단거리무선단말기(DSRC), 휴대폰단말기, 신용카드 등을 이용한 통행료징수방식은 차량 내부에 양방향통신이 가능한 별도의 단말기가 있어야 가능하며 신용카드를 소지한 보행자가 통과할 경우 자동요금징수 될 우려가 있다.Toll collection using short range wireless terminal (DSRC), mobile phone terminal, credit card, etc. requires a separate terminal that enables two-way communication inside the vehicle, and may cause automatic toll collection when a pedestrian with a credit card passes. .

접촉식 검지센서(루프검지기)를 이용한 번호판 인식카메라(2)는 검지능력이 우수하나 접촉식 검지센서(3)가 도로공사, 차량통행으로 파손되는 등 문제점이 있다. 비접촉식 검지센서(5)를 이용한 번호판 인식카메라(2)는 물리적인 도로공사, 차량통행 동절기 노면 결빙 등에 영향을 받지 않아 유지관리에 매우효과 적이다. 따라서 교통량이 집중되는 혼잡구간(7)을 선정하여 구간 시점부(8) 및 종점부(9)에 번호판 인식카메라를 설치함으로 혼잡통행으로 인한 통행료징수 또는 부제위반차량을 검출이 가능하여 간선도로 소통악화를 억제하고 신호교차로와 유입교통량의 교통류관리에 효과적인 기술적 통제수단이 확보하는 것이 목적이다.License plate recognition camera (2) using a contact detection sensor (loop detector) has a good detection ability, but there is a problem such that the contact detection sensor 3 is damaged by road construction, vehicle traffic. License plate recognition camera (2) using a non-contact detection sensor (5) is very effective in maintenance because it is not affected by physical road construction, road traffic ice freezing in winter. Therefore, by selecting the congestion section (7) where the traffic is concentrated and installing license plate recognition cameras at the section starting point (8) and the terminal section (9), it is possible to detect toll collection or subtitle violations caused by congestion traffic, thereby deteriorating traffic on the main road. The aim is to ensure that technical controls are effective in the control of traffic flows at signaling intersections and inflows.

상습적으로 발생되는 혼잡구간(7)에 차량번호판 인식을 이용하여 통행료를 자동 정산처리하여 차량진입을 억제 또는 우회분산처리 유도함으로 도로의 소통기능을 회복하고 교통유발시설물의 차량이용실태를 감시하여 적절한 통제대책을 수립하고 통행금지차량을 검출도 가능하다.By using the license plate recognition in the congestion section (7), which occurs frequently, the toll is automatically settled, thereby restraining the entry of the vehicle or inducing detour dispersion, thereby restoring the communication function of the road and monitoring the vehicle usage of the traffic-causing facility. It is also possible to establish control measures and detect curfew vehicles.
