The study focused on the creation of an efficiently functioning system, the key element of which is the cross-city section. It has been pointed out that the route of the cross-city section will be the main factor that will determine the level of use of railways in journeys within the city limits. Therefore, the current condition of the Wrocław Railway Junction was analyzed in terms of adapting it to the needs of LRT, focusing primarily on the best accessibility of travelers to system. Places where new stops should be created to increase the attractiveness of agglomeration transport have been indicated. In the following points, three variants of system are proposed depending on the route of the cross- city route. In the summary, the most advantageous variant was indicated and the use of hybrid sections (road-rail) was proposed as one of the solutions that could improve the transport network in the city in the near future.

This directive will enter into force on 17 December 2021. This means that, at least for employers with 250 or more employees, the effective date of the provisions will be December 17, 2021. The directive provides for the possibility of postponing the implementation of obligations for entities employing 50 to 249 until December 17, 2023. employees. The obligation to protect whistleblowers will apply to all entrepreneurs employing more than 50 employees, but this criterion does not apply if the entrepreneur is covered by one of the EU acts listed in Annex I to the directive. This applies, inter alia, to regulations concerning financial aspects or AML (counteracting money laundering and terrorism), entities that participate in public procurement tenders or use EU funds as part of their activities. Then the entrepreneur is to be subject to the obligations to implement the whistleblower protection requirements, regardless of the number of employees. Additionally, the directive explicitly encourages the national legislator to extend the obligations also to other areas of law and a broader scope of entrepreneurs. Therefore, it will be specified in the Polish act implementing the Directive.","PeriodicalId":52762,"journal":{"name":"Przeglad Komunikacyjny","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44790904","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 calculations were made with application of the KR5 pavement structure and temperature data obtained from 50 meteorological stations and from the period of 30 years from 1989 to 2019, provided by the Institute of Meteorology and Water Management. The influence of variable traffic with heavy vehicle traffic was taken into consideration, both during the day and throughout the year. It was presented how the values of the equivalent temperature change in the territory of Poland depending on the location of the meteorological station. The computational analysis showed the variability of the equivalent temperature on the territory of Poland in the range from 14.68°C (Suwalki) to 16.99°C (Tarnow).The weighted mean value of the equivalent temperature for the entire year is 16.01°C and it is higher than the value adopted in the catalogue of typical flexible and semi-rigid structures that is equal to 13,00°C. The change in the equivalent temperature value on the designed thickness of asphalt layers of the pavement structure has been also assessed in the paper.

The influence of rubber additive, on rheological properties, viscosity, penetration, softening point of the asphalts were analyzed. An innovative technique based on the combined use of microscopic observations was developed. Tests results were compared to the conventional asphalts. Positive effects of modification were recorded. Two types of asphalt mixtures were prepared on the same mineral aggregate. For reference a Stone Matrix Asphalt (SMA) was used with polymer modified (PM) asphalt 45/80-55. Then the Stone Matrix Asphalt was prepared on the base of asphalt-rubber (45/80-55 AR). These materials were tested on rutting and water and frost resistant. The results indicated that the SMA mixtures prepared on the base of rubber modified asphalt exhibit greater resistance to permanent deformation, at elevated temperatures and greater water and frost resistance than the conventional SMA mixtures. Tests results were compared to technical requirements for SMA layers. It was found that this type of asphalt mixture can be successfully used in road surfaces, especially exposed to freezing.
