While the number of passengers using urban railroads is increasing day by day, the number of complaints from passengers is also increasing. In order to resolve problems caused by poor communication between urban railroad officials and passengers in this paper. An IOS application using the Internet of Things (IoT) technology is proposed for providing safety and comfort temperature service(s) and for taking prompt action(s) of passengers complaints. In this proposal system, the temperature & humidity sensors were placed in a suitable location within the train. At the same time, transferring measurements to the remote server, allowing passengers to request their desired temperature through the IOS Application. Like this based on the collected data, I suggest a system that urban railroad officials can control temperature & humidity of the train. The proposed system was implemented by the Gwangju Metro Line 1 to validate its effectiveness.

Aviation's safety record continues to improve yearly, especially with respect to passenger and crew injuries and deaths. However, although the number of accidents has decreased over the decades, there are still many events, such as landings short of the runway and runway excursions, both of which pose threats to passenger and crew safety. Surviving any kind of aviation accident depends on the physiological threat and stress of the impact(s), the extent to which the physical structure surrounding the passengers and crew remains intact, and the ability of the passengers and crew to be able to escape the wreckage. The one action that both passengers and crew can carry out to help decrease the likelihood of crash-related injury or death is to assume an emergency brace position. Doing so has been demonstrated over several decades to improve survivability. While cabin crew are taught (and then might have to teach passengers in an emergency about the emergency brace position), passengers in many parts of the world never learn about the brace position unless they are involved in an emergency in which there is time to prepare for the landing. This lack of provision of information is related to the fact that most airlines do not provide information in the preflight safety briefing and some do not even provide the information in the passenger safety cards. Many countries do not require their airlines to do so, a fact, which in turn, is related to the lack of mention of the brace position in ICAO's Annex 6. Until standards and recommended practices are changed at the highest world level, passengers will continue to be deprived of this vital, life-saving information that they can use, potentially to help save their own lives.

This paper proposed a dynamic transit vehicle simulation model and a dynamic transit passengers simulation model, which can simultaneously simulate the transit vehicles and passengers traveling on a transit network, and also developed an algorithm of dynamic departure time choice model based on individual passenger. The proposed model assumes that each passenger's behavior is heterogeneous based on stochastic process by relaxing the assumption of homogeneity among passengers and travelers have imperfect information and bounded rationality to more actually represent and to simulate each passenger's behavior. The proposed model integrated a inference and preference reforming procedure into the learning and decision making process in order to describe and to analyze the departure time choices of transit passengers. To analyze and evaluate the model an example transit line heading for work place was used. Numerical results indicated that in the model based on heterogeneous passengers the travelers' preference influenced more seriously on the departure time choice behavior, while in the model based on homogeneous passengers it does not. The results based on homogeneous passengers seemed to be unrealistic in the view of rational behavior. These results imply that the aggregated travel demand models such as the traditional network assignment models based on user equilibrium, assuming perfect information on the network, homogeneity and rationality, might be different from the real dynamic travel demand patterns occurred on actual network.

Regulation (EC) No 261/2004 ("Regulation") is a common rule on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights. In some recent cases of European nations, passengers sued the air carrier in order to obtain monetary compensation under Article 7(1) of the Regulation. Some courts dismissed the actions on the grounds that, unlike denied boarding or cancellation of the flight, the Regulation provides no compensation in relation to delayed flights. However, Court of Justice of the European Union(CJEU) ruled that Regulation 261/2004 must be interpreted to mean that passengers whose flights are delayed have a right to compensation in cases when the loss of time is equivalent to, or is in excess of three hours - where the passengers eventually reached their final destination three hours or more later than the originally scheduled arrival time. It is true that a strict interpretation of the regulation would suggest that passengers whose flight has merely been delayed are not entitled to compensation. They should only be offered assistance in accordance with the Articles 6 and 9. Nevertheless, the Court recognized the same right to the same compensation for passengers of flights delayed by more than three hours as that explicitly provided for passengers of cancelled flights. On the one hand, the Court bases this ruling on the recitals of the Regulation, in which the legislature links the question of compensation to that of a long delay, while indicating that the Regulations seek to ensure a high level of protection for passengers regardless of whether they are denied boarding or their flight is cancelled or delayed. On the other hand, the Court interprets the relevant provisions of the Regulation in light of the general principle of equal treatment. Furthermore, the Court delivered a ruling that the loss of time inherent in a flight delay, which constitutes an inconvenience within the intention of Regulation No 261/2004 and which cannot be categorized as 'damage occasioned by delay' within the meaning of Article 19 of the Montreal Convention, cannot come within the scope of Article 29 of that convention. Consequently, under this view, the obligation under Regulation No 261/2004 intended to compensate passengers whose flights are subject to a long delay is in line with Article 29 of the Montreal Convention. Although the above interpretation of the Court can be a analogical interpretation, the progressive attitude of the Regulation and the view of Court forward to protect passengers' interest is a leading role in the area of international air passenger transportation. Hopefully, after the model of the positive support in Europe, Korea can establish a concrete rule for protecting passengers' right and interest.

The main purpose of this paper is to estimate the impact of exchange rate and economic business activity on the passengers' demand for international transportation. The demand pattern depends upon the transport vehicles that the global passengers take. The global passengers' demand for transportation is modelled as exchange rate, industrial production and seasonal dummy variables. The seasonality is found in both water and air, but the former is far greater than the latter. All series span the period January 1990 to December 2008. The empirical results of this paper reveal that the income elasticity of sea transport is greater than that of air one, all of which are positive. The study also shows that the exchange rate has an significant impact on the demand for air transport, whereas it is insignificant in water transport. The impulse response function indicates that passengers increase steadily before peaking seven to eight months after the shocks to economic business activity and decline very slowly to its pre-shock level. The air passengers also respond negatively to the shocks in exchange rate and the impacts of exchange rate shock seem to decrease relatively slowly, while the water passengers respond positively after six months. The industrial production shocks remain above equilibrium for more than twenty four months, while the exchange rate shocks remain below equilibrium for more than twenty four months. Boosted by improved economic conditions worldwide, international tourism has recovered faster than expected from the impacts of the global financial crisis and economic recession of late 2008 and 2009. These facts suggest that the demand of global water transport has the high possibility of growing steadily and continuously.

When new subway lines are considered to construct in a large city, there is a need to establish the appropriate transfer systems between subway and other transit modes, so as to increase the use of subway system. In this study, a multi-nominal logit model is developed to analyze the travel characteristics and the mode choice of subway Passengers transferring to and from the buses, minibuses and taxi. These passengers represent a large Portion of transit Passengers in Pusan city It shows that the explanatory variables that affect Passengers\` mode choice are in order of OVIT(Out-of-Vehicle Travel Time), IVTT(In-Vehicle Travel Time), transit fare,. income, gender, and age in modeling. In particular, OVTT is shown to have more significant impact on the mode choice than IYTT due to the fact that transfer trip is involved only in a short distance. Variables associated with the travel costs, however, do have an insignificant impact on the mode choice. It shows that it would be a better Policy to improve the quality of transit service using additional financial resource by increasing transit fare rather than by reducing the fare to increase travel demand. It also shows that value of travel time of OVTT is remarkably higher than that of IVTT and value of travel time of taxi Passengers is much higher than that of minibus Passengers .

The Seoul metropolitan subway system can be represented by a graph which consists of nodes and edges. In this paper, we study classification of subway stations and trip behaviour of subway passengers through partitioning the graph of the subway system into roughly equal groups. A weight of each edge of the graph is set to the number of passengers who pass the edge, where the number of passengers is extracted from the transportation card transaction database. Since the graph partitioning problem is NP-complete, we propose a heuristic algorithm to partition the subway graph. The heuristic algorithm uses one of two alternative objective functions, one of which is to minimize the sum of weights of edges connecting nodes in different groups and the other is to maximize the ratio of passengers who get on the subway train at one subway station and get off at another subway station in the same group to the total subway passengers. In the experimental results, we illustrate the subway stations and edges in each group by color on a map and analyze the trip behaviour of subway passengers by the group origin-destination matrix.

When unforeseen accidents occur in a ship, it is important to save passengers safely and remove them from the accident area quickly. To solve such a situation, site information of passengers on board always must be identified. This paper implemented a site monitoring of crews and passengers based on the BLE and PLM combination, to prepare for unexpected accidents of the ships. This system was composed of BLE tag for crews, passengers and each room, PLM networks, data server, and monitoring PC. In this system, site information derived from the tag attached to the bodies and cabins of crews and passengers are transmitted through a power line network, and monitored on the screen of a monitoring PC. The proposed system guides them into the only authorized area considering the ship security and passengers' safety, and even has a special alarm call to warn them after entering an unauthorized area. This system enables the BLE-embedded tag battery to use for a long time because the BLE consumes low electric power, and can gain an economic advantage.

The ultimate aim of this research is to analyze the effects of on-line word of mouth (WOM) regarding airlines on behavior intention of airline passengers through information accommodation, attitude and trust. For the purpose, we have carried out a questionnaire survey with passengers who have used airline social media and websites as target, and analyzed a total of 362 copies of the questionnaire using structural equation. As a result of analysis, on-line WOM turned out to have a significant effect on accommodation, and the accommodation turned out to have significant effects on attitude and trust. Also, attitude turned out to have a significant effect on trust, and the trust turned out to have a significant effect on behavior intention. This research has significance in that it can help establish a WOM marketing strategy of airlines through grasping the actual situation of on-line WOM of airlines and present a possibility of WOM marketing utilizing social media as an appropriate marketing for aviation industry. At the same time, it also has an academic significance in that it predicted actual behavior intention of passengers who have used on-line WOM on airlines.

The elevator system which is operated nowadays at skyscrapers, apartments and enterprises does not offer standby passengers any information of which floor the elevator is going to stop or skip. This study will introduce the system that shows the Passengers a running schedule of the elevator. If this system is utilized for current systems, it will bring so much benefit such as shortening waiting time or choosing alternatives for the passengers. Furthermore, this system will be set up not stopping the floor for the passengers who choose alternatives like using stairs or escalators with using toggle switches. This will be efficient to save the electric power.
