Taxi's queue for entering into taxi stand makes traffic jam and congestion around taxi stand. If we make that taxi waits in another place around taxi stand, and can approach to taxi stand when it gets in its turn, these traffic jam and congestion around taxi stand can be reduced. In this paper, we propose entry sequence operating system for taxi stand to reduce traffic jam and congestion around taxi stand. In this system, taxi driver can request his sequence number, and the system issues sequence number to driver. When it is time to approach to taxi stand due to issued sequence number, the proposed system notifies to taxi driver via taxi terminal. Taxi getting the proposed service can wait in another place around taxi stand, and can approach to taxi stand after receiving notify for approaching. Therefore, the proposed system in this paper can reduce traffic jam and congestion around taxi stand because it can reduce or get rid of taxi's queue around taxi stand. We implement the taxi stand approach sequence management system proposed in this paper for taxi stand installed in Chungju-Si, Chungbuk. We use Google Cloud service and Android platform for implementing.

Professional taxi driver exposure to indoor air pollutants has been a subject of concern in recent years because of higher levels of air pollutants, comparing to the surrounding atmosphere. This study evaluated the potential exposure to respirable suspended particulate (RSP), nitrogen dioxide $(NO_2)$ and volatile organic compounds (VOCs; benzene and toluene) for professional taxi drivers inside each of 10 vehicles in Pusan, comparing weekday (Monday and Thursday) and weekend (Saturday). Indoor mean concentrations of RSP inside vehicle were $53.88\;ug/m^3\;and\;75.52\;ug/m^3$ on weekday and weekend, respectively. Measured indoor $NO_2$ concentrations were 28.32ppb and 40.69 ppb, respectively. Benzene and toluene mean concentrations inside vehicle were 5.41 ppb and 11.36 ppb, respectively. Considering no smoking of taxi drivers inside vehicle, closed window in winter, and increased usage of taxi on weekend, source of indoor air pollutants inside taxi might be mainly suggested from the number of passenger's carried, faulty exhaust systems, and engine and carburetor evaporative emissions.

The Purpose of this Paper is to compare and analyze the operational condition of corporation-owned and owner-driver taxies using tachometer output data. The empirical findings from this study are as follows : First, although corporation-owned taxies have long operating mileage and service driving mileage per vehicle. the service rate of owner-driver taxies were 3.5 percent higher than corporation-owned taxies. Secondly it is found that operation mileage, service driving mileage, and service Income except non-service driving mileage have statistically significant differences between corporation owned and owner-driver taxies. In addition. there was a weak correlation between the income and non-service driving mileage of owner-driver taxies. It is concluded that owner-driver taxies joined the call-taxi association and call-taxi services decreased non-service driving mileage.

Mobile application is growing explosively with the advent of a new technology: smartphones. Mobile application is a new marketing channel and performs as a start-up platform. This study examines the effect of mobile application on the off-line market. Despite the continuous declining demand for taxi service, paradoxically, the supply of taxi service has increased. The taxi industry can be categorized into general taxi and call taxi. General taxi is accidental and inefficient because it has to search for its own passenger. As call taxi takes the request of a passenger, it is more efficient than general taxi. However, the current defective passenger-taxi driver matching system and insufficient taxi driver management hinder the development of the call taxi market. Differences in differences (DID) is an econometrical methodology that examines whether or not an event has meaningful influence. This research uses DID to investigate the effect of the Kakao taxi application on the call taxi industry. Furthermore, it examines the effect of major companies' reckless diversification, which is considered unethical behavior. The passengers of call taxi data from August 2014 to July 2015 and those of designated driving service data of the same period were collected as the control group.

Taxi drivers are exposed to vehicular exhaust aerosols which are a mar source of atmospheric lead pollution in Korea where lead additives are incorporated in petrol. To investigate the blood lead concentration, their correlation factors and influences on taxi drivers, samples were collected from 90 taxi drivers who were living in the Taegu City, during August, 1989. Blood lead concentration was estimated by the atomic absorption spectrophotometer (IL.551) equipped with flameless furnace atomizer (IL.665). The results were analyzed statistically and compared with control group selected urban population. The mean blood lead concentration of taxi drivers and control group were $26.34{\pm}6.53{mu}g/dl\;and\;20.77{\pm}4.80{\mu}g/dl$ respectively (p<0.01). No significant correlation was observed between the blood lead concentration of taxi drivers and driver career (r=0.093). There were no difference of statistical significance in the blood lead concentration of smokers and nonsmokers.

In 2008, according to Statistics Korea's population over the age of 20 and 26.3% of the smokers, 73.7% were non-smokers, smokers and non-smokers by smoking of 22.0% was reported. 336 people of 255 people (75.9%) is currently also showed that smoking. Hypertension, 48 people(14.30%), the boundary type of high blood pressure 193 people (57.40%) of them, especially for high blood pressure appear as a systematic management is required. 336 people targeting taxi drivers smoking and blood pressure, and the relevance of the reserch results did not show a statistically significant difference. Current smokers of 336 people surveyed 255 people (75.90%), respectively. Men over 15 years old in Korea smoking population (1990) was reported as 73.2%, Lee 2001, according etc. Korea 61.8% of the adult male smoking rate is quite high as compared to what is reported. Taxi drivers are working in very bad working conditions. The health of a taxi driver affect the safety of customers were considered.

Purpose: The purpose of this study was to determine the relationship between customer contact service and mental health among Korean taxi drivers. Methods: This was a secondary analysis of data collected from the 2015 Korean Working Conditions Survey. The sample included 496 taxi drivers in South Korea. The effect of customer contact service on mental health was analyzed using logistic regression analysis. The independent variables were general characteristics, working conditions, and hazardous factors in interactive service. Results: The prevalence of poor mental health was 56.3%. Taxi drivers experienced emotional involvement (17.2%), hiding feeling (32.0%), and contact with angry clients (18.3%) in their job. During the first month of their work, 33.7% experienced verbal abuse and 12.3% threats/humiliating behaviors. In bivariate analysis, verbal abuse, threats/humiliating behaviors, and physical violence were associated with mental health of taxi drivers. Multiple logistic regression analysis revealed 'emotional involvement' and 'contact with angry clients' were significant predictors of mental health. Conclusion: The findings of this study may be useful in developing intervention programs to improve the mental health of taxi drivers in South Korea.

For professional drivers, there is a possibility to have musculoskeletal disorders on ankle joint due to repetitive pedaling operation. Therefore, this study have focused to examine ankle active range of motion (AROM), dorsiflexor strength, and pressure pain threshold (PPT) of tibialis anterior muscle (TA) in taxi drivers compared to a age-matched control group. Thirty male taxi drivers with at least 10 years of driving experience and thirty male sedentary workers were evaluated for ankle AROM, dorsiflexor strength, and PPT of TA. Multiple independent t-tests were used to identify significant differences between two groups. For the results, taxi drivers had significantly less AROM in dorsiflexion and greater AROM in external tibial rotation compared to the control group. Also, dorsiflexor strength and PPT of TA in taxi drivers was significantly lower than in the control group. This study indicates that the repetitive ankle movements associated with driving have an effect on ankle AROM, dorsiflexor strength, and PPT of TA and may lead to work-related musculoskeletal disorders on ankle. Professional drivers may need to be educated to prevent a potential musculoskeletal disorders associated with repetitive movement.

Purpose: This study aimed to comprehensively examine middle-aged male taxi drivers' perceptions of the risk of cardiovascular disease. Methods: A qualitative method was used, with focus group interviews. The participants were middle-aged male taxi drivers who had been driving for more than ten years and for more than six hours daily. Results: The data were analyzed using qualitative thematic analysis. Middle-aged male taxi drivers' perceptions of the risk of cardiovascular disease were categorized into three main themes: "individual perceptions of cardiovascular disease", "possibility of behaviors for cardiovascular disease" and "motivations of behaviors for cardiovascular disease". Six sub-themes were extracted as follows: "perception of vulnerability", "perception of seriousness", "perception of profitability", "perception of disability", "self-awareness" and "advancing toward health care". Conclusion: It is necessary to invigorate support systems through measures including education, counseling, and web-based programs to prevent cardiovascular disease in middle-aged male taxi drivers.
