For this reason, such changes are regulated at the European Union (EU) level through a dedicated legal act known as the Common Safety Method for risk assessment (CSM). The example presented in this paper is a portion of the analysis carried out for an Estonian freight carrier with a bowtie method, which we improved so that it fully complies with the CSM requirements. This analysis concerns a change consisting of allowing the possibility of a freight train being driven by one person (with no assistant driver). The case study presented in the paper, although limited due to confidentially issues, allows a full description of how to use the proposed method in real-world applications.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45359808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the individual purchase history, our comprehensive analyses document evidence that an elevated level of concentrations of fine particulate matter caused a substantial change in individual decisions on public transit ridership in relation to individual social and economic characteristics. The estimated effect primarily arose from the fear of exposure to pollutants and, consequently, is substantially different from other macroeconomic influences. Our empirical results contribute important inferences about commuters’ choices of transit modes during the period of ambient air pollution and offer significant guidance for policymakers and practitioners.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47116976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of cargo bikes is seen as a possible solution. The direct reason for this research is the observation that there is still room for a new type of cargo bike that meets the needs of the outlined target groups. This article summarises how the quality function deployment (QFD) method has been used for the systematic development of an electric cargo tricycle that meets these needs. The developed tricycle distinguishes itself from existing cargo bikes mainly by its loading capacity, stability and manoeuvrability. The prototype tests performed by professional couriers were so positive that a pilot series was built.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46926755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an urban island point of view, two important issues have been raised: the distribution of jobs, Therefore, basic facilities, and services within an urban island and the travels of people between urban islands. social exclusion can be determined either by the affordability/acceptability of travel time/cost to access the minimum requirement of facilities/services or the number of facilities/services in reach of the individuals within acceptable/affordable travel time and cost. A person will be at risk of social exclusion if they belong to a minority group as opposed to the majority in the same society. Some levels of social exclusion risk have been proposed. The evaluation should be implemented at the meso-level (urban island). From the view of the urban islands, the issues of transportrelated social exclusion are clearly understood, and measurements of social exclusion should be solved. We feel that a detailed survey/interview is needed for areas at high risk of social exclusion, followed by an evaluation at the micro-level to identify excluded people and the causes for their exclusion. It is expected that this paper will attract researchers to pay more attention to this issue.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45025342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, algorithms are developed for calculating the probability of random noise accepting critical values, a coefficient of correlation between the critical values of the noise and the useful component, and a relay cross-correlation function.

The first one concerns the identification of disruptions during ground handling that have an impact on the scheduled completion of ground handling. The second problem is determining how these disturbances affect the environment by estimating the increased fuel consumption of the aircraft. In the first step, a catalog of disruptions in the ground handling process of the aircraft, which delays the performance of subsequent aircraft operations, was developed. Simio software was used to analyze the impact of disturbances on the performance of ground service, in which random disturbances were simulated. The simulation was run for several variants, taking into account the sample aircraft and various airlines. The developed model allows for the analysis of the impact of disturbances on the punctual performance of the ground service of the aircraft for various variants with given probability values. In the next step, simulations were performed to determine the impact of the disturbances on the increase in fuel consumption by the aircraft. Research has shown that even minor disruptions increase an aircraft’s fuel consumption over a 200-km flight path. The analyzes carried out in this work are of great importance for sales agents and airlines who strive to minimize the duration of elementary activities and eliminate threats during ground handling. Additionally, it is important from the point of view of environmental protection. As research has shown, even small disturbances can substantially increase fuel consumption, which is not beneficial for airlines. Past research has focused on the analysis of fuel consumption by aircraft and emissions during takeoff and landing operations and taxiing aircraft. There is a large correlation between the disturbances occurring at the parking place and increased fuel consumption, which is important from an economic and environmental point of view.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46162363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
