This study aims to determine the shortest route in the application of online transportation services which is the main attraction for entrepreneurs who want to start looking for their fortune in technology and transportation, given the enormous opportunity where the human population is very large. increased, and some human activities had to be carried out. fulfilled. Some online transportation service companies use paid features provided by Google to determine the shortest distance and route, thus costing a lot of money. In this study, to determine the shortest route on a journey, it is necessary to calculate using an algorithm method, namely the dijkstra algorithm which is an algorithm used to solve the problem of the shortest route or the shortest path from one point to another at a point. weighted graph, The distance between vertices is the weight value of each edge in the graph. A graph that has a weight must be positive (weight >= 0). Dijkstra's algorithm itself uses a greedy strategy in its operation, where in each step the chosen one with the smallest weight connects the selected node with other nodes that have not been selected. Keywords: dijkstra algorithm, online transportation service, shortest route,

The purpose of this study is to examine the effect of automation attributes in railway digital ticket payment toward the commuters' satisfaction and retention in railway transportation. Digital payment security is one of the essential qualities which was little discussed in determining public transportation service performance. This study used the partial least square structural equation modeling method study to measure the six effects indicated by the proposed research framework to fill the last research gap. The results showed two automation attributes, reliability and security, significantly influenced commuter satisfaction, supporting the behavioral theory as commuter satisfaction also substantially affected the commuters' retention attitude. This study revealed that the reliability factor was the most significant. The findings communicate important insight for local government in improving its railway transportation's quality of service. The study's scope was to train commuters who live in Jakarta metropolitan area and use the railway as their public or mass transportation.

Mobility as a service (MaaS) integrates various transportation modalities and connects these modalities to enable users to travel from departure points to destination points. The objectives of this study were to analyze the factors influencing the intention to use MaaS and determine a direction for the implementation of this service. Hence, this study utilized an ordered probit model and marginal effect analysis. Specifically, a survey was conducted based on citizens living in Gyeonggi-do, South Korea, to prepare logical MaaS operation measures customized in this province. Subsequently, variables related to MaaS were classified, and statistical analysis was performed based on these variables. The need for integrated transportation service, intention to use shared mobility, gender, household income, and region are found to have significant effects. Moreover, demographic groups with high levels of intention to use MaaS were identified. Finally, the intention to use MaaS was found to be mainly affected by whether public transportation was the primary means of transportation or whether the subjects spent a comparatively long time commuting. It is expected that these findings will serve as the basis for MaaS implementation in the future and will also be used as fundamental data for transportation service planning.

Abstract Even before the Covid-19 pandemic, spouse carers of persons with dementia (PwDs) found their care responsibilities overwhelming and had little time to focus on their own lives. To minimize the risk of being infected with Covid-19, older persons are recommended to self-isolate in their homes, while formal support such as respite care and day care centers are withdrawn. This study involved semi-structured interviews with 24 spouse carers of community-living PwDs, with the aim of describing their situation during the pandemic. The interviews were analyzed with qualitative content analysis. Results revealed that they commonly declined help because of the perceived risk of their spouse being infected with Covid-19 and thus also possibly causing their death. They described feelings of being trapped in their situation, as they experienced having no choice than take all responsibility for the care of their partner themselves, with cost of being unable to take necessary breaks. This was described as making an already strained situation almost unbearable, which led to conflicts with their partner. However, the spouses also described positive aspects due to strategic changes in health and social care provision to prevent the spread of the virus, such as greater staff continuity in home care services, and patient transportation service. These made the PwD less stressed and influenced their everyday life positively. It could be concluded that the extent burden during the Covid-19 pandemic calls for extensive development of tailored support to better tackle the rapid changes that can occur in a society.

Motivated by the needs of modern transportation service platforms, we study the problem of computing constrained shortest paths (CSP) at scale via preprocessing techniques. Our work makes two contributions in this regard: 1) We propose a scalable algorithm for CSP queries and show how its performance can be parametrized in terms of a new network primitive, the constrained highway dimension. This development extends recent work that established the highway dimension as the appropriate primitive for characterizing the performance of unconstrained shortest-path (SP) algorithms. Our main theoretical contribution is deriving conditions relating the two notions, thereby providing a characterization of networks where CSP and SP queries are of comparable hardness. 2) We develop practical algorithms for scalable CSP computation, augmenting our theory with additional network clustering heuristics. We evaluate these algorithms on real-world data sets to validate our theoretical findings. Our techniques are orders of magnitude faster than existing approaches while requiring only limited additional storage and preprocessing.

Realizing an environmentally friendly city of Denpasar is one of the balancing concepts in the development of an environmentally friendly city. Changing the mode of transportation to environmentally friendly transportation, such as the use of bicycles, can prevent congestion. One of the government's real actions is the government's authority on bicycle lanes as a necessity for the community. The purposes of this study are to reveal the form of authority of the Denpasar City Government in Streamlining the Application of Bicycle Paths and forms of legal protection for bicycle lane users based on Law Number 22 Year 2009 in Denpasar City. The type of legal research used in this research is empirical legal research with a statutory approach. The data collection techniques were carried out by reading, recording, quoting, summarizing and analyzing the data and information obtained from the relevant agencies, namely the Denpasar City Transportation Service. After obtaining primary legal materials and secondary legal materials which are then processed and analyzed systematically, data is obtained that the authority of the Denpasar City government in making the use of bicycle lanes effective is to provide bicycle lane facilities at several points scattered in the Denpasar City area, such as on Jalan Sudirman , Jalan Letda Made Putra, Jalan Letda Tantular and at several other points. Meanwhile, legal protection for bicycle lane users contains the rights of bicycle lane users, such as the mandatory provision of bicycle lane facilities by the government to ensure the safety and comfort of cyclists, freedom from fear in traffic, and avoidance of traffic hazards.

The purpose of this research article is to develop a hybridization between the Failure Mode and Effect Analysis (FMEA) method and the Combinative Distance-Based Assessment (CODAS) method under Pythagorean Fuzzy environment. The traditional FMEA procedure is based on the multiplication between the parameters of severity, occurrence, and detectability where everyone has equal relative importance; therefore, different combinations of these parameters can generate the same result creating uncertainty in the analysis. In this mode, the hybridization proposed in this research deal with relative importance of each parameter; in the fact to have a more suitable combination which consider the level of knowledge of the experts in the assessment. Finally, a numerical case was carried out concerning the public transportation service to validate our proposal; the results show that 31 failure modes and potential risks can be evaluated using user perceptions, a dominant with high level of knowledge about the public transportation service and an apprentice or common user, as team of experts and exploiting the subjectivity of the information in a mathematical model. Also, we compare the results with a variation of the proposed model with the multi-criteria method multi-objective optimization method by relationship analysis (MOORA); it was observed that the convergence of the failure modes depends on the nature of the mathematical model even under the same conditions at the start.

Earning Management is one of the various efforts that can be made by companies in engineering the numbers in the financial statements so that the company's financial statements can be seen in good condition for investors and other readers. This study aims to determine the effect of free cash flow and financial leverage on earnings management with good corporate governance as a moderating variable in transportation service companies. This study uses data from 26 transportation service companies from 2017-2019 that have been listed on the Indonesia Stock Exchange. The data analysis technique used in this study is the Partial Least Square (PLS) analysis method where PLS analysis is an analytical method that is not based on many assumptions or conditions and can handle many variables at once even though there is multicollinearity in these variables. The results show that free cash flow and financial leverage have no effect on earning management and good corporate governance cannot moderate the relationship between free cash flow and financial leverage on earning management.
