The paper investigates the current distribution of traffic safety signs on the urban road by type and facility and examines the installation compliance rate. The study area is Pangyo Techno Valley of the high tech industrial complex in Sungnam, Gyeonggi, where traffic safety signs are investigated, and the traffic accidents severity of the concerned roadway segment is analyzed by road type. The analysis found that when the urban roads are grouped as intersections and roadway, such variables as accident type and violation of the law have impacts on the traffic accidents severity. This implies that the accident reduction requires the traffic safety signs closely related with traffic accidents severity. The paper suggests the systematic and sustainable development of the database of traffic safety signs in order to continuously analyze the impact of the traffic safety signs on the accidents reduction.

Recently, traffic accidents caused by high-risk drivers such as elderly drivers have emerged as a major social problem. People feel uneasy about driving by high-risk drivers, so it is argued that they should be institutionally restricted from driving. However, it is difficult to determine suitabilities of driving by inspecting factors that affect the actual driving abilities. For elderly drivers, restricting their driver licenses can be factors infringing on mobility rights. For this reason, a prudent approach is needed to improve the driver aptitude test system. In order to solve this problem, if the driver license is determined by assessing physical and cognitive abilities which are identified to affect driving, it will be a better system which all ages agree. In this study, human factors that can influence driving were analyzed by comparing between cognitive abilities and driving behaviors using a driving simulator. Cognitive abilities of 65 subjects were measured using special apparatus. The results of measured cognitive abilities were used to categorize into two groups which were with good abilities and with poor abilities. Next, driving behaviors of the subjects in various road environments were analyzed through collected log data using a driving simulator. First, it was confirmed that the subjects with relatively higher age belonged to the group with poor cognitive abilities. Second, the group with good cognitive abilities showed better driving behavior than the worse group. Third, it was analyzed that there were more differences in urban roads between two groups. Fourth, it is confirmed that there were more differences in driving behavior among the groups at nighttime than at daytime. The results of this study are meaningful because this was carried out empirical studies to find the factors affecting driving behaviors. This research can be used to carry out future research on the driver license and driving behaviors.

The seriousness of traffic accidents occurring on expressways means the need for safe driving of freight vehicles. In order to prevent drowsy driving due to long-time driving of trucks, the corresponding Act was revised in 2016 to ensure that truck drivers should take at least 30 minutes of rest after four hours of continuous driving. In addition, the Korea Expressway Corporation, an expressway operator, is trying to provide sufficient rest areas for truck drivers. For here, it is important to construct them in appropriate locations on the truck route to avoid a waste of budget. Therefore, this study analyzed Toll Collection System (TCS) Origin/Destination (O/D) data and selected the most overlapping traffic links from ranking 1st to 4th for both directions, and showed the most appropriate locations using ArcView. As a result, the service areas with truck parking spots are located within the range of both directions, but there is only one sleeping shelter in the range. In addition, the traffic volume in the direction to Mokpo (South bound) shows twice more than that to Seoul (North bound). Therefore, it is necessary to prioritize the service areas’ location within the selected range first and south bound direction requires more facilities. For the future research, the authors recommend to study about adequacy size of service area with the analysis of truck driver’s behaviors. It is expected to contribute making a decision for investment priority of the budget.
高速公路交通事故的严重性意味着货运车辆安全驾驶的必要性。为了防止卡车长时间驾驶造成的疲劳驾驶，2016年修订了相应的法律，规定卡车司机在连续驾驶4小时后至少要休息30分钟。另外，高速公路运营公司韩国道路公社也在努力为货车司机提供充足的休息场所。在这里，重要的是在卡车路线上的适当位置建造它们，以避免浪费预算。因此，本研究通过分析Toll Collection System (TCS) Origin/Destination (O/D)数据，在两个方向上从第1 - 4名中选择重叠最多的交通链路，并使用ArcView显示最合适的位置。因此，有卡车停车位的服务区位于两个方向的范围内，但范围内只有一个睡觉的地方。此外，前往木浦方向(南行)的交通量是前往首尔方向(北行)的2倍。因此，有必要优先考虑服务区域在选定范围内的位置，南向需要更多的设施。建议在今后的研究中，结合货车司机的行为分析来研究服务区域的充分性大小。预计将有助于决定预算的投资优先次序。

The demand forecasting for rail has been analyzed with zone-based OD data at macroscopic level analysis, and two type of transportation mode choice model are separately applied for national-wide analysis and metropolitan area analysis each by using the zonal OD data in South Korea. This zone-based analysis has fundamental limitations due to the spatial aggregation. It cannot analyze the various effects according to the traveler’s individual attributes on the mode choice behavior, which is inevitable limitation of the zone-based analysis in aspect of forecasting accuracy. However, the zone-based analysis is unavoidable for analyzing large-scale areas such as the national-wide area or metropolitan area. Therefore, this study aims to build a transportation mode choice model with improved accuracy of the model than the currently used model within limitations of the zone-based analysis. In particular, the study tried to reflect travel time and service frequencies of various transit modes between an OD pair into the traveler’s behavior model in a more realistic way. The suggested model can explain the phenomenon that the travel time differently affects the traveler’s mode choice behavior by the travel distance. This study also was performed to verify logically that the proposed model explains more realistically the choice behavior by testing the value of time and elasticity. A case analysis was included to show how the analysis results may vary depending on the mode choice model to be applied.

Unlike existing studies dealing with factors affecting crash occurrences, this study attempted to analyze underlying factors related to driver’s human factors. In general, it is known that human factors leading to the crash occurrence include drowsiness, aggressiveness, and inattention etc. This study mainly focused on underlying factors resulting in such human factors that have been widely addressed to date in the area of traffic safety. Crash investigation systems focus on the road geometry, road environment factor and the driver’s risk driving behavior, human factor. However, less efforts have been made in collecting data related to internal factors of crashes that affect driving behavior. For example, the internal factors include taxi driver’s health characteristics, living conditions and taxi company’s working environment. The purpose of this study is to derive the factors of taxi company’s safety level and to propose a new direction for taxi safety consulting. In-depth interviews with commercial taxi drivers and managers of taxi companies were conducted to collect survey data to represent internal factors associated with driver’s working and welfare environments. In addition to a multiple linear regression, a binomial logistic regression and a random forest analysis technique were adopted to derive underlying internal factors to be used to identify the level of traffic safety taxi companies. The results show that the identified contributing factors include weekly working hours, accident-involved vehicle management, privately-used hour, narrow space inside the vehicle, fatigue management, and the level of life satisfaction. The countermeasures for enhancing taxi safety were discussed in terms of improving working environment and welfare of taxi drivers.

Mobility as a service (MaaS), which integrates information of travel modes and its related services into a single platform, has generated considerable recent attention and research interest owing to its convenience. Recently Korean government planned to launch the MaaS which integrates existing and innovative mobility services by providing booking and payment through a single application, thus provides convenient, seamless travel experience to domestic people. Although many researchers anticipate MaaS will bring a shift from car-centric to transit-centric mobility pattern, it is also possible that MaaS increase ridership of fossil-fuel vehicle. Understanding the impact of MaaS on people’s choice behavior beforehand is critical to successfully implement MaaS and to minimize social disorder. Thus, the objective of our research is to investigate user preference to transport alternatives available in the MaaS system. We conducted a stated choice experiment with five alternatives including mode combinations and obtained 1,556 valid samples. We developed two separate nested logit models which can assuage independence of irrelevant alternatives problems. Each model showed satisfying results in that the values of robust r-square were 0.297, 0.310, respectively. Finally, we revealed how socio-economic variables, workplace variables affect the preference of each nested structure. The results of this paper will be helpful to platform operators when building marketing strategies and designing a customized travel mode recommendation system.
移动即服务(Mobility as a service, MaaS)将出行方式及其相关服务的信息集成到一个单一的平台上，由于其便利性，近年来引起了人们的广泛关注和研究兴趣。最近，韩国政府计划推出MaaS，通过一个应用程序提供预订和支付，将现有的和创新的移动服务整合在一起，为国内民众提供方便、无缝的旅行体验。尽管许多研究人员预计MaaS将带来从以汽车为中心到以交通为中心的移动模式的转变，但MaaS也有可能增加化石燃料汽车的客流量。事先了解MaaS对人们选择行为的影响，是成功实施MaaS、减少社会混乱的关键。因此，我们研究的目的是调查用户对MaaS系统中可用的运输方案的偏好。我们进行了包括模式组合在内的五种方案的陈述选择实验，获得了1556个有效样本。我们开发了两个独立的嵌套logit模型，可以减轻不相关替代问题的独立性。各模型的稳健性r平方分别为0.297、0.310，结果令人满意。最后，我们揭示了社会经济变量、工作场所变量如何影响每个嵌套结构的偏好。本文的研究结果将有助于平台运营商制定营销策略和设计定制出行模式推荐系统。

The traffic safety signs of the city are, under the Road Traffic Act, are mostly installed on the roadside, however they have been likely to be unrecognized due to roadside trees and other facilities. The parallel installation of road markings and traffic safety signs or preferential installation of road markings may be a solution to this problem, however this cause problem because priorities in the effectiveness of road markings and traffic safety signs are legally clear. The purpose of this study was, therefore, to analyzes the gaze time and compliance rate for each installation method by using eye tracking for speed limit, slow speed, no-entry, and stop among regulatory signs for the two-way and four-lane roads in the city and to analyze the visual gaze rate using Visual Attention Service (VAS). The results showed that the parallel installation of the traffic safety sign and road marking increased the gaze time and the gaze rate and level were higher in road marking than those in columnor arch-attached signs. The results of this study are expected to be used as a fundamental data in determining policies such as amendment of standard about traffic safety sign and road markings in city.

As of 2018, the mobility handicapped population accounts for about 29% of the total population, which is expected to increase continuously. Various studies are actively underway to ensure the increasing convenience of the mobility handicapped. In order to introduce these new policies and technologies, satisfaction evaluation should be performed for the system under development. Therefore, in this study, a user satisfaction survey was conducted for the route guidance system for the mobility handicapped in railway stations. This study consists of three stages: sample and questionnaire design, field demonstration and satisfaction survey, data processing and analysis. A questionnaire survey was conducted in Busan City Hall station for 33 visually impaired people, and satisfaction with the system and user requirements were investigated. As a result of the survey, the satisfaction level of the railway before using the system was 4.13 points and 7.34 points after use, and as a result of investigation of the intention to use the system, about 84.8% of respondents said that they intend to use the route guidance system if it is introduced. The results of user satisfaction surveys conducted in this study can be used as a basis for more stable system development.
