    This research aims to clarify the influence of driver visibility on the crossing accidents. We investigated 1,101 accidents happened in the 621 intersections of in Hakata-ku ward, Fukuoka-city from 2015 to 2017. We calculated yearly accident rate at each intersection based on the accidents data and evaluated driver visibility with surveyed intersections information. It was found that the accident rate was high when the visibility was bad regardless of the number of lanes on the secondary road at the location where many accidents occurred, and the accident rate was high when the number of lanes on the secondary road was low throughout Hakata Ward.

    Traffic accidents are decreasing year by year, but intersection accidents, such as collisions, remain common and have a high fatality rate. Intersection accidents are more common at specific intersections, with only about 14.8% of all intersections having intersection accidents in Fukuoka City in the three years. It is believed that the occurrence of intersection accidents could be reduced by avoiding those intersections. This study surveyed the around Hakata Ward, Fukuoka City, where many intersection accidents occur, and created route guidance that considered the number of past accidents in intersection and verified its effectiveness by comparing it with the shortest-distance route.

    Although the number of traffic accidents across Japan has been decreasing year by year, there are some intersections in Fukuoka City where traffic accidents have increased from the year 2019 to 2020, i.e. before and after the pandemic. Our results show that, there are 34,464 intersections in Fukuoka City, and traffic accidents have occurred at 6,569 intersections (19%), while at 463 intersections (1.3%), traffic accidents have increased. Among these 463 intersections, car-to- pedestrian and car-to-bicycle accidents are relatively higher and most of these intersections have road width more than 5.5m and have a footpath. The reasons for the high number of car-to-pedestrian and car-to-bicycle accidents are the pedestrians and cyclists entering the intersection from both directions, and measures for pedestrians and cyclists may be necessary to reduce the number of accidents.

    With increase in vastly available accident data, visualizing and studying the characteristics illustrated by the data becomes significantly challenging. In this paper, we used RStudio to generate biplots using Principal Component Analysis (PCA) technique to analyze the data. We studied 128,059 accidents occurred in Fukuoka prefecture from the year 2016 to 2019 and established the relation between the attributes and variables in the data. Resulting plots facilitate ease of interpretably, macroscopic overview of data and ability of verifying all the dimensions at the same time. Hence, we propose using biplots for analyzing characteristics of traffic accidents at a glance.

    This paper shows the characteristics of crossing collisions based on actual accident data of crossing collisions and intersection data. Fukuoka is a prefecture with third highest crossing collision. We surveyed Fukuoka City, which has the highest number of accidents, and analyzed 7,330 crossing collisions and 10,436 intersections in the city. The roads in Fukuoka City are composed of 41% crossroads, 57.9% junctions, and 1.1% a five-forked road, but since 65.3% of accident intersections are crossroads, crossing collisions is likely to occur at crossroads. It was also found that the type of traffic light and the stop line position influences on the occurrence of the accident.

    We clarified the differences in the causes of crossing accidents between urban and suburban areas. We selected Hakata Ward and Nishi Ward in Fukuoka City as urban and suburban areas respectively. Based on the data of 1,348 accidents that occurred from the year 2015 to 2017, we analyzed the environment factors of 1,997 intersections that included the intersection where the accident occurred and the surrounding intersections. Our results show that accidents occurred at the crossroads of Nishi Ward were found to be approximately 15% more than that occurred at crossroads in Hakata Ward. Furthermore, it was found that the number of intersections with no traffic signal, no stop line and with stop line drawn before the usual in Nishi Ward was more when compared to Hakata Ward.

    Car-to-bicycle accidents account for 40% of all crossing collisions, hence preventive measures are required. We analyzed 1,367 car-to-bicycle accidents that occurred in Fukuoka City from 2015 to 2017. According to the analysis, accidents occurred more frequently at 8:00 am and 5:00 pm, and tend to occur more frequently during the day than at night. It was also found that the rate of accidents by teenagers and female cyclists was high, when analyzed by parties involved and attributes such as age and gender. On further research, focusing on the intersections with frequent accidents, we found that bicycle colliding to the car from left contributed to about 60% of accidents, Hence, it is necessary to reduce the traffic approaching from right side to the bicycle from the sidewalk.

    This paper shows the analytical results of the relation between crossing environments and traffic accidents for preventing collision accidents. There was 1,447 accidents in Hakata ward, Fukuoka city from 2015 to 2017. We investigated the information of 1,297 intersections such as a crossroad and traffic lights. The number of accidents in crossroad is as twice as that of T junctions. This is why crossing collisions occur between parties going straight on frequently. In addition, many accidents occurred in crossroads which there are less than three lanes in subsidiary roads.

    Crossing collision accidents are greatly influenced by environmental factors. We investigated the relationship between the environmental factors at the 1,629 intersection in Hakata-ku, Fukuoka City and the situation of the accident, and found that there were many accidents caused by straight traffic on the crossroads. In this study, we tried to clarify the cause of the accidents by investigating the mutual effects of multiple environmental factors. As a result of the analysis, it became clear that the reverse of the stop line increased the accident frequency by about 1.7 times regardless of the presence or absence of traffic lights. In addition, it was found that the frequency of accidents can be reduced by about 10% by improving the outlook by installing curved mirrors, and it was also revealed that there is a possibility of suppressing accidents by the outlook improvement measures.

    Aiming widespread use of wireless power transmission, optical wireless power transmission at wavelength of 975 nm between vertical cavity surface emitting laser (VCSEL) arrays and a single crystalline Si solar cell was studied. The power generation efficiency of the cell was measured as high as 33% which was higher than the efficiency of 18% at the time of irradiation with sunlight. This is because the transmission loss is mainly eliminated. However, further reduction of the electrical resistance of the solar cell is necessary because the efficiency decreases with increasing incident energy.

    Al2O3 was deposited on silicon nanowire (SiNW) arrays by atomic layer deposition (ALD) as a passivation layer to reduce surface recombination velocity. As a result, effective minority carrier lifetime was improved from 1.82 to 26.2 μs. From this result, the relative low-surface recombination rate of 2.73 cm/s was obtained from a calculation using one-dimensional device simulation (PC1D). The performance of SiNW solar cells was also simulated by considering the surface recombination velocity on the side of SiNWs using two-dimensional device simulation. It was found that Al 2O3 deposited by ALD can improve open-circuit voltage of SiNW solar cells even if the structure has a high-aspect ratio and large surface area. Therefore, improvement in the performance of SiNW solar cells can be expected.

    The electrical characteristics of silicon nanowire (SiNW) solar cells with p-type hydrogenated amorphous silicon oxide (Eg=1.9 eV)/n-type SiNWs embedded in SiO2/n-type hydrogenated amorphous silicon (E g=1.7 eV) structure have been investigated using a two-dimensional device simulator with taking the quantum size effects into account. The average bandgap of a SiNW embedded in SiO2 increased from 1.15 eV to 2.71 eV with decreasing the diameter from 10 nm to 1 nm due to the quantum size effect. It should be noted that under the sunlight with AM1.5G the open-circuit voltage (Voc) of SiNW solar cells also increased to 1.54 V with decreasing the diameter of the SiNWs to 1 nm. This result suggests that it is possible to enhance the Voc by the quantum size effect and a SiNW is a promising material for the all silicon tandem solar cells.

    This paper describes a low-cost 48 × 48 element thermal imaging camera intended for use in measuring the temperature in a car interior for advanced air conditioning systems. The compact camera measures 46 × 46 × 60 mm. It operates under a program stored in the central processing unit and can measure the interior temperature distribution with an accuracy of ±0.7°C in range from 0 to 40°C. The camera includes a thermoelectric focal plane array (FPA) housed in a low-cost vacuum-sealed package. The FPA is fabricated with the conventional IC manufacturing process and micromachining technology. The chip is 6.5 × 6.5 mm in size and achieves high sensitivity of 4,300 V/W, which is higher than the performance reported for any other thermopile. This high performance has been achieved by optimizing the sensor's thermal isolation structure and a precisely patterned Au-black absorber that attains high infrared absorptivity of more than 90%. The package incorporates a wide-angle zinc sulfide (ZnS) lens that is fabricated using moulding technology. The field of view is 60 deg. by 60 deg. The performance of the sensor is suitable for measuring car interior temperatures.

    This paper describes three low-cost infrared focal plane arrays (FPAs) having a 1,536, 2,304, and 10,800 elements and experimental vehicle systems. They have a low-cost potential because each element consists of p-n polysilicon thermocouples, which allows the use of low-cost ultra-fine micro-fabrication technology commonly employed in the conventional semiconductor manufacturing processes. To increase the responsivity of FPA, we have developed a precisely patterned Au-black absorber that has high infrared absorptivity of more than 90%. The FPA having a 2,304 elements achieved high resposivity of 4,300 V/W. In order to reduce package cost, we developed a vacuum-sealed package integrated with a molded ZnS lens. The camera aiming the temperature measurement of a passenger cabin is compact and light weight devices that measures 45 × 45 × 30 mm and weighs 190 g. The camera achieves a noise equivalent temperature deviation (NETD) of less than 0.7°C from 0 to 40°C. In this paper, we also present a several experimental systems that use infrared cameras. One experimental system is a blind spot pedestrian warning system that employs four infrared cameras. It can detect the infrared radiation emitted from a human body and alerts the driver when a pedestrian is in a blind spot. The system can also prevent the vehicle from moving in the direction of the pedestrian. Another system uses a visible-light camera and infrared sensors to detect the presence of a pedestrian in a rear blind spot and alerts the driver. The third system is a new type of human-machine interface system that enables the driver to control the car's audio system without letting go of the steering wheel. Uncooled infrared cameras are still costly, which limits their automotive use to high-end luxury cars at present. To promote widespread use of IR imaging sensors on vehicles, we need to reduce their cost further.

    A novel IPD (intelligent power device) technology for an automotive high-side switch has been developed which is applicable to devices up to the 60-V range. The fabrication process includes only one-time epitaxial growth. A new vertical DMOS FET with built-in cellular Zener diodes has also been developed. The avalanche capability of the DMOS is about 10 times greater than that of the conventional one. The control circuits of the developed IPD are protected against battery line transients by a 60-V Zener diode between the VDD and VSS terminals and two voltage limiters.

    Optical Wireless and Fiber Power Transmission Conference (OWPT) is an international conference on optical wireless power transmission, optical fiber power transmission, and related technologies. The 1st Optical Wireless and Fiber Power Transmission Conference (OWPT2019)†1 was held on April 23 (Tue.) - 25 (Thu.), 2019 at PACIFICO Yokohama in Yokohama, Japan as one of conferences of the OPTICS & PHOTONICS International Congress 2019 (OPIC2019)†2. OWPT2019 was intended to provide a central forum for the update and review of scientific and technical information on optical wireless power transmission and optical fiber power transmission covering a wide range of fields from fundamental research to systems and applications. This conference was sponsored by Optical Wireless Power Transmission Committee, The Laser Society of Japan in cooperation with several academic societies and associations.
    Optical wireless power transmission and optical fiber power transmission, which are power transmission methods using light, are attractive compared with existing wireless power transmission using electromagnetic wave because method using light has various advantages such as long-distance transmission, small size, no-electromagnetic interference, etc. The methods may lead to improvement of convenience of electrical equipment, application to a system in where power supply becomes a problem, and creation of a new system. Though this system has high feasibility based on light source and solar cell, there are only limited research and development application cases until now. Therefore, there has been no appropriate place to discuss the related devices, systems, and applications, and the first international conference was decided to be held in order to support the future extension of this field and to activate it. In this conference, there is the significance of strengthening the intensive discussion of various themes as well as the networking of the optical power supply related researchers.
