Road traffic accidents are a leading cause of premature deaths and globally pose a severe threat to human lives. In particular, pedestrians crossing the road present a major cause of vehicle–pedestrian accidents in South Korea, but we lack dense behavioral data to understand the risk they face. This paper proposes a new analytical system for potential pedestrian risk scenes based on video footage obtained by road security cameras already deployed at unsignalized crosswalks. The system can automatically extract the behavioral features of vehicles and pedestrians, affecting the likelihood of potentially dangerous situations after detecting them in individual objects. With these features, we can analyze the movement patterns of vehicles and pedestrians at individual sites, and understand where potential traffic risk scenes occur frequently. Experiments were conducted on four selected behavioral features: vehicle velocity, pedestrian position, vehicle–pedestrian distance, and vehicle–crosswalk distance. Then, to show how they can be useful for monitoring the traffic behaviors on the road, the features are visualized and interpreted to show how they may or may not contribute to potential pedestrian risks at these crosswalks: (i) by analyzing vehicle velocity changes near the crosswalk when there are no pedestrians present; and (ii) analyzing vehicle velocities by vehicle–pedestrian distances when pedestrians are on the crosswalk. The feasibility of the proposed system is validated by applying the system to multiple unsignalized crosswalks in Osan city, South Korea.

The occurrence of serious traffic accidents due to driving error has recently become a social issue. The decline in cognitive functions is considered a factor particularly among elderly drivers, for which some corrective measures are urgently needed. Currently, as a measure dealing with elderly drivers, drivers aged 75 years are required by law to examine their cognitive functions when they renew their driver’s license. This examination is conducted to measure memory and power of judgment. In the present study, we used a device that allows simple measurements and attached electrodes to the frontal pole, where it is easy to attach; measure electroencephalograms for the cognitive functions of memory, mental calculations (thinking), and memory recall; and examine the changes in the power spectra to determine how they vary in young and elderly individuals.

Background: Chronic subdural hematoma (CSDH) is usually associated with good recovery with burr hole irrigation and postoperative drainage under local anesthesia. In Japan, traffic accidents by the elderly drivers over 65 years old are severely increasing, and there is no consensus on whether or not to return to driving after CSDH treatment. We perform a postoperative cognitive assessment. We retrospectively investigated the return-to-driving rate and associated factors. Methods: Of the 45 patients over 65 y.o. and who had usually driven, 30 patients wished to drive again. We performed tests composed of Mini-Mental State Examination (MMSE), line cancellation and line bisection task, Kohs block design test, trail making test (TMT)-A and B, Kana-hiroi test, Rey-Osterrieth complex figure test, and behavioral assessment of the dysexecutive syndrome, in order. When all tests’ scores were better than the cutoff values, we let patients drive again. When some of the scores were worse than the cutoff values, we reevaluated the patients at the outpatient every month. If the patients’ scores could not improve at the outpatient, we recommended them to stop driving. Results: Nineteen of 30 patients could return to driving. Worse MMSE, Kohs block design test, TMT-A, TMT-B scores, higher age, dementia, or consciousness disturbance as chief complaints were associated with driving disability. Conclusion: CSDH is known as treatable dementia. However, we should perform an objective cognitive assessment before discharge because only 63% of the patients over 65 y.o. who wished to drive could return to driving.

The Relationship

Recently in Japan, traffic accidents caused by elderly drivers have attracted public attention. Elderly drivers are judged whether they can continue driving based on the cognitive test results at the renewal of their driver's license. However, it has not been to lead to the reduction of accidents. Therefore, it is important to understand the relationship between cognitive impairment and driving behavior for elderly drivers. In this study, we analysis on the relationship between cognitive impairment and driving behavior for elderly drivers. The driving ability is evaluated using the data of driving behavior during starting/stopping. Regression models that explain the relations between cognitive impairment of an elderly driver and driving ability were estimated.
