과적차량은 도로 및 교량 구조물과 도로 횡단 시설물 등에 손상요인으로 작용하며 기존의 단속 시스템은 축조작 및 인력부족등 많은 문제점을 내포하고 있어서 이에 대한 대처방안이 요구되고 있다. 이에 본 논문에서는 주행중인 과적차량의 지능형 임베디드 단속 시스템 개발을 위하여 유전자 알고리즘 기법을 적용, 도로자체를 저울로 하여 주행중인 차량의 하중 및 주행정보를 분석을 연구하였으며 이를 통하여 효율적인 과적 단속이 이루어 질 수 있다고 판단된다. 또한 USN구성을 위한 임베디드 센서와 함께 Internal/External Network의 무선화 시스템을 통한 사용자 중심의 시스템을 구축하는 것이 최종 목적이므로 향후 WCDMA/HSDPA를 이용한 External Network의 구성과 실제 과적 단속 적용을 위하여 Test Bed를 통한 실험이 실시되어야 할 것이다.

도로 과적 차량은 일반 승용차보다 도로를 많이 훼손하여 도로, 교량의 사용 수명을 단축시키고, 유지보수 비용을 상승시키는 원인으로 분석되고 있다. 또한 과적 화물차량은 정상차량에 비해 도로 주행 흐름을 상대적으로 떨어뜨려, 도로 용량을 저하시키며, 소음과 진동의 발생, 배기가스 배출 등 여러 가지 문제를 발생시키는 원인이다. 특히, 도심지에서의 화물차 운행은 선진적인 단속체계가 더욱 필요하다. 현재의 단속시스템은 단속인력과 계측장비를 설치한 고정식의 과적 검문소를 운영하거나 이동식의 단속 검문을 병행하는 방식이다. 그러나 도심지의 경우, 교통정체, 고정식 검문소의 부지 확보 등 현실적으로 단속업무를 실시하기 어려운 환경이다. 본 논문에서는 현재 운영하는 고정식의 단속시스템을 자동 단속시스템으로 전환시키기 위한 기술적 구성 방안에 대해서 검토하였다.

On January 16 to May 31, 2012, Korea Expressway Corporation was carried out an pilot overweight enforcement using high-speed weigh-in-motion at Gyeongbu expressway 195.0k (Gimcheon) and Jungbunaeryuk expressway 119.5k (Seonsan). In this study, it is attempted to analyze the practical effect of high-speed weigh-in-motion by comparing the average total weight and traffic volume of eight weeks before and after the these overweight enforcement, respectively. The main results are as follows: First, the result of analysis of the change in average total weight and traffic volume, it was found that it did not differ after as in previous traffic volume, and the total weight is reduced. This means that the total weight is not reduced by decreasing freight traffic, but by decreasing the total weight. Therefore, it can be seen that there is an effect of pilot overweight enforcement using high-speed weigh-in-motion. Second, the average total weight and total weekly traffic volume decreased rapidly starting from the start of the overweight enforcement, but there was showing a tendency to increase gradually again.

Overloaded Vehicles are one of biggest of hazard in durability decrease of roads and bridges. Thus, regulation was put in force about overloaded vehicles to reserve this problem. However, existing system had many problems. For these reasons, this paper presents solutions of U-intelligent overload vehicles regulation system based on manless and wireless for fixing of problems of existing system and construction of u-lTS. With this in mind, we studied about composition method of system, applications of USN, design of system controller, WCDMA/HSDPA and we verified performance of WIM Sensors in this paper.

This paper is a type of business representatives who are responsible for the burden he want to relieve. In addition, to ensure transparency and to contribute to the Elimination of irregularities in cracking down on overcharging to research. In order to avoid duplicate entry of fixed checkpoints of modern equipment was installed in the automatic collection of information inspection. And, if the information is the same information to crack down imposed the Road Fine system linkage system Constrution CALS system to research. Land administration office imposed a fine after confirmation information to crack down on the auditory system, the auditory crackdown imposed fine and proceed to determine the status of your work since. This study was carried out and any future crackdown on overcharging gathering information for the efficient production of surgical intervention for improved accuracy considering that frequency.

Overload vehicles have demoralizing influence upon the social overhead capital, economics of nation, traffic flow and road safe as various components. Accordingly, this study established a ubiquitous sensor network system to develop an intelligent regulation system to monitor overloaded vehicles in motion. and Unlike WIM, after detecting the axle of driving vehicles by measuring deformation of roads, this system calculates the weights of vehicles by using signals from the strain sensors installed under the road and an analysis method. Also the study conducted an simulation test for vehicle load analysis using genetic algorithm. and tested wireless sensor for USN system.

Korea has achieved significant economic growth with building the Gyeongbu Expressway. As the number of new road construction projects has decreased, it becomes more important to maintain optimal status of the current road networks. One of the best ways to accomplish it is weight enforcement as active control measure of traffic load. This study is to develop High-speed Weigh-in-motion System in order to enhance efficiency of weight enforcement, and to analyze patterns of overloaded trucks on highways through the system. Furthermore, it is to review possibilities of developing overweight control system with application of the HS-WIM system. The HS-WIM system developed by this study consists of two sets of an axle load sensor, a loop sensor and a wandering sensor on each lane. A wandering sensor detects whether a travelling vehicle is off the lane or not with the function of checking the location of tire imprint. The sensor of the WIM system has better function of classifying types of vehicles than other existing systems by detecting wheel distance and tire type such as single or dual tire. As a result, its measurement errors regarding 12 types of vehicle classification are very low, which is an advantage of the sensor. The verification tests of the system under all conditions showed that the mean measurement errors of axle weight and gross axle weight were within 15 percent and 7 percent respectively. According to the WIM rate standard of the COST-323, the WIM system of this study is ranked at B(10). It means the system is appropriate for the purpose of design, maintenance and valuation of road infrastructure. The WIM system in testing a 5-axle cargo truck, the most frequently overloaded vehicle among 12 types of vehicles, is ranked at A(5) which means the system is available to control overloaded vehicles. In this case, the measurement errors of axle load and gross axle load were within 8 percent and 5 percent respectively. Weight analysis of all types of vehicles on highways showed that the most frequently overloaded vehicles were type 5, 6, 7 and 12 among 12 vehicle types. As a result, it is necessary to use more effective overweight enforcement system for vehicles which are seriously overloaded due to their lift axles. Traffic volume data depending upon vehicle types is basic information for road design and construction, maintenance, analysis of traffic flow, road policies as well as research.

Load managing method on road became necessary since overloaded vehicles occur damage on road facilities and existing systems for preventing this damage still show many problems. Accordingly, efficient managing system for preventing overloaded vehicles could be organized by using the road itself as a scale by applying genetic algorithm to analyze the load and the drive information of vehicles. First of all, accurate analysis of load using the behavior of road itself is needed for solving illegal axle manipulation problems of overloaded vehicles and for installing intelligent embedded load analyzing system. Accordingly in this study, to use the behavior of road, the transformation was measured by installing underground box type indoor model and indoor experiment was held using genetic algorithm and 10% error were checked.
