This study analyzes the current wearing status and awareness of warning clothing for elementary school students as well as to identify points of improvement for traffic accident prevention and clothing safety education. A survey was conducted on 279 elementary $5^{th}$ and $6^{th}$ graders in the Incheon area and Ansan in 2017 June & July. The results showed that more than 2/3 of participants had no experience wearing warning clothing. Second, 63% of participants answered 'traffic accident prevention' as the main purpose of warning clothing, showing that about 2/3 are aware of the importance. Third, yellow was the most preferred color of fluorescent material for warning clothing with a significant difference of preference by grade. The favorite color combination of participants was yellow & orange followed by yellow & light green, but showed a significant difference between boys and girls. Fourth, the most preferred form of warning clothing was fluorescent short sleeves and shorts without reflective tape, suggesting that students paid more to the purpose for reflective tape. Fifth, while 68% of participants were negative towards wearing safety clothes that are currently available, 66% were willing to try safety clothes if the color and the design improved. The results suggest an improved education with more emphasis on the purpose of clothing safety. Color and design adjustment of the current warning clothing is also recommended for a more active participation by elementary school students.

We surveyed 223 road workers between 2017 July-August about wearing and satisfaction in order to find basic data to develop safety clothing that enhances visibility of motion and comfort while meeting international standards. It was found that most of the current warning clothing owned by road cleaners and about 2/3 of policemen clothes were provided by public institutions. The purpose of wearing, color, properties, satisfaction and protectiveness differed significantly by occupation. Second, the most popular response for the type and quantity of warning clothing was 2 sets of spring/autumn, summer, and winter type for road cleaners, whereas policemen chose 2 sets of all types plus a safety vest. Therefore, a top-level (3rd class) warning clothing study is required. Third, satisfaction ranked Moderate>Good>Poor; in addition, the main reason for satisfaction was that 'retroreflective tape increases safety at night (54.4%)' for road cleaners and 'the fluorescent color stands out (43.7%)' for policemen. Thus, it was accepted that visibility contributed to safety. Fourth, body-protectiveness was evaluated higher compared to wearing satisfaction, and it was recognized more by road cleaners than policemen. Overall satisfaction was higher for road cleaners versus policemen both in Seoul than Incheon. Fifth, the main dissatisfaction in both groups was 'low sweat absorbency' showing improving the air permeability, moisture regain and permeability was the highest priority. Finally, those working 8 hours a day tended to evaluate more positively the 6 properties of the material.

As rate in an elderly population and expanding their range of activity rapidly increase, the demographics of the elderly population on a use of transportation also rise. Elderly pedestrians often find it difficult to react promptly to the traffic accidents as they are less perceptive of the dangers present under the situation. More than half of the elderly traffic accidents are elderly pedestrian accidents in road. Therefore, we design and implement smart safety hat for safety of elderly pedestrian. The smart safety hat binds stripe-shaped LED around a hat in order for a driver to perceive pedestrian easy and quickly. Features of smart safety hat include controlling the number of LEDs by using a light sensor and warning through vibration using a sound sensor. Also, we used Bluetooth to communicate with the smartphone to enable user customization of the light and numbers of LEDs.
