운전면허시험을 응시하는 사람들은 면허취소 등으로 재시험을 보는 사람들도 있지만, 대부분 자동차를 운전하기 위해 최초로 운전을 배워 시험을 응시하는 사람들이 대부분이다. 자동차 운전은 생명과 직결되는 것으로 초기의 정확한 운전습관이 무엇보다 중요하다. 특히 사회에 첫 진출을 하면서 운전면허를 취득하는 사람들이 많기 때문에 처음 운전을 배울 때 객관적이고 공정한 기준에 의해 올바른 운전능력을 평가받아 면허를 취득하는 것이 매우 중요하다. 본 논문을 통해 구현하고자하는 시스템은 효율적이면서도 공정하고 정확한 자동화 채점을 통해 양질의 운전자를 배출할 수 있는 S/W 설계 및 주요 기능들에 대해 고찰, 제안하였다. 이를 통해 자동채점 운전면허 시스템 개선을 제안하여, 교통사고를 예방하고 올바른 운전을 통해 교통사고를 줄이는데 목적이 있다.

The aim of this study was to evaluate driving performance of Healthy and disabled groups (with or without driver's license) to control steering wheel by using steering assistive devices in the driving simulator. The persons with partial loss of use of all four limbs have problems in operation of the motor vehicle because of functional loss to operate steering wheel. Therefore, if steering assistive devices for grasping the steering wheel are used to control the vehicle on the road in persons with disabilities, the disabled persons can improve mobility in their community life by driving a motor vehicle safely. Ten healthy subjects (with or w/o driver's license) and ten subjects with physical disabilities (with or w/o driver's license) were involved in this study to evaluate driving performance to operate steering wheel by using four types of steering assistive devices (Single-pin, V-grip, Palm-grip, Tri-pin) in driving simulator. STISim Drive 3 software was used to test the steering performance in four scenarios: straight road at low and high speed of vehicle (40 km/h and 80 km/h), curved road at low and high speed of vehicle (40 km/h and 80 km/h). This study used two-way ANOVA in order to compare the effects of two factors (type of steering assistive device and subject group) in the three dependent variables of driving performance (the lateral position of vehicle, standard deviation of lateral position representing the variation of the left and right movement of the vehicle and the number of line crossing). The mean values of the three dependent variables (lateral position, standard deviation of lateral position, the number of line crossing) of steering performance were statistically significantly smaller for the healthy or disabled groups with driver's license than the other groups without driver's license on the curved road at high speed of vehicle compared to low speed of vehicle.

Objective: The aim of this study was to develop the adaptive device for severe physical disabilities using smart device in the driving simulator and its performance evaluation. Development of appropriate driving adaptive device for the people with serious physical limitation could contribute to maintain their community mobility. Background: There is lack of adaptive driving devices for the people with disabilities in Korea. However, if smart device systems like iPod and iPhone are used for driving a car, the people with serious physical limitations can improve their community mobility. Method: Both gyroscope and accelerometer from iPod were used to measure the tilted angle of the smart device for driving. Customized Labview program was also used to control three axis motors for steering wheel, accelerator and brake pedals. Thirteen subjects were involved in the experiment for performance evaluation of smart device in simulator. Five subjects had driver licenses. Another four subjects did not have driver licenses. Others were people with disabilities. Results: Average driving score of the normal group with driver license in the simulator increased 46.6% compared with the normal group without driver license and increased 30.4% compared with the disabled group(p<0.01). There was no significant difference in the average driving score between normal group without driver license and disabled group(p>0.05). Conclusion: The normal group with driver license showed significantly higher driving score than other groups. The normal group without driver license and disabled group could improve their driving skills with training in simulator. Application: If follow-up studies would be continued and applied in adapted vehicle for on road environment, many people with more severe disabilities could drive and improve the quality of life.

Purpose: For patients with CNS injury who are restricted in the use of public transportation, car driving means more than simple movements and is essential for their independent lives, such as participation in society and returning to jobs. Therefore, in order to enhance the quality of life of disabled persons, their high perception and necessity of driving rehabilitation are required. The purpose of this study is to determine the perception and necessity of driver rehabilitation in patients with CNS injury. Methods: In order to survey the perception of patients with CNS injury and necessity of driving rehabilitation, questionnaires were distributed to patients with CNS injury. Questionnaires were composed of demographic characteristics, disability related characteristics, and driver's license related characteristics. Results: Our results showed that the number of driving participants with a driver's license for the disabled was significantly higher than that for non- driving participants with a previous general driver's license in the perception of driving rehabilitation. Conclusion: We suggest that driving rehabilitation for patients with CNS injury should be supported in terms of evaluation and treatment.

Recently, the structure of simulation environment is important issue in all fields. In case of the training for operating the machines which are costly such as airplanes or spaceships, simulators could be helpful for decreasing the costs and training effects by simulating real situation. When we get the driving license, too many peoples are waiting for their turns because of limited cars and testing spaces in Korea. To solve this problem, we've designed and developed the basic design for the simulators. We suggested the Computer 3D Simulation Model for practice of a drives's license. The concept of this simulator was from a 3D Racing-game which suit for driving exercise. We provide users with handle-controlled simulation setting in order that users feel reality as if they drive really through this simulator. We also use 'force-feedback' system which give handle vibration in case users collide against obstacles or exceed the line since users can absorb the simulation program and feel the sense for the real. This paper is the study about modeling the driving exercise model made use of 'computer 3D simulation', and producing and utilizing the simulator through this modeling.

The focus of this study is to redesign the Korean license plate by comparing the USA's plate with European plate formed by 1-line system in order to increase a read rate of Korea license plate. And we have compared the read rate of the new design license plate with that of the present license plate and that of the license plate studied so far. As an experimental method (used in a precedent research), we use three kinds of methods that are the measurement of the read-distance, the measurement reading-rate under the short-term exposure and the measurement of the reading-rate when driving. First, three kinds of measurements for plates of five nations are performed. Then we redesign the new Korean license plate under the base of read rates obtained by five nation's plate. As alternatives, we choose five license plates. Those alternatives are the redesigned license plate, the present license plate, the license plate studied so far, and two types of eternity license plates made by the Korea Transport Institute. When we compare results of the read-distance, there is no significant in term of different the read-distance between the alternatives. But there is a significant difference in term of the misreading-rate and the read-rate when diving. Therefore, it is necessary to redesign the present license plates because of a high misreading-rate.

In this paper, we propose a license plate detection method of running cars in various road images. The proposed method first classifies the road image into day and night images to improve detection accuracy, and then the tail-light regions are detected by finding red color areas in RGB color space. The candidate regions of the license plate areas are detected by using symmetrical property, size, width and variance of the tail-light regions, and to find the license plate areas of the various sizes the morphological operations with adaptive size structuring elements are applied. Finally, the plate area is verified and confirmed with the geometrical and image features of the license plate areas. The proposed method was tested with the various road images and the detection rates (precisions) of 84.2% of day images and 87.4% of night images were achieved.
