Most of heavy trucks and buses are propelled with diesel engines beacause of their reliability, fuel efficiency and tourqe. These engines are simple to maintain, cheap to produce and extremly durable. Main propblem with diesel engines are solid hazard particles emission and nitrosoxide.

This paper develops and tests advanced CV-based multi-level conditional Transit Signal Priority (TSP). The algorithms are using the latitude/longitude (lat/lon) coordinates of CV vehicles and intersections to establish communication, share information and request priority. The TSP strategies are implemented through controllers’ built-in features and logic processor, using Econolite ASC/3 as a representative traffic signal controller. The tests were performed in VISSIM microsimulation with the ASC/3 Software-in-the-Loop (SIL) controller emulator. State Street in Salt Lake City, UT, is selected as a test-case corridor. The paper shows that the developed signal control priority (SCP) algorithms are successful in reducing delays for target vehicles in excess of 6%, without significant impacts on other traffic. The information obtained from CV vehicles can be used to further enhance control algorithms and create adaptive SCP programs.","PeriodicalId":32747,"journal":{"name":"Put i Saobracaj","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69273274","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}

Considering that most of the literature so far does not take an explicitly critical attitude towards this emerging technology, this paper considers the great uncertainties and implications for the socio-technical domains in and out of everyday mobility. The analysed implications also refer to the set of innovation actors, as well as the institutions and patterns of interaction between them. The conclusion is that the technological transition of MaaS from a niche to a mobility regime requires the convergence of several socio-technical factors of societal digitalization, the development of a wider infrastructure, and a regulatory system change. To avoid the potential undesired effects of MaaS, transport policy and institutions for managing technological development will need to recognize the underlying problems at the root of further activities, ranging from depoliticization to fundamental theoretical questions about the essence of the mobility commons.","PeriodicalId":32747,"journal":{"name":"Put i Saobracaj","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47157534","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, the importance of roads and railways continues to gain in importance even in the age of digital highways. Many traffic routes have a century-old tradition. They are located in valleys and notches for overcoming mountains and mountain ranges. The design and maintenance of these traffic routes are particularly complex. An important part of this task is protection against stone impact in the mountains, but also in hilly areas. Even if there was no danger of rocks falling for decades or it was not known: due to climate change, the impact of water, the process of freezing and thawing and the growth of tree roots, there can be a significant risk.","PeriodicalId":32747,"journal":{"name":"Put i Saobracaj","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69273260","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}

Exploring the relationship of taxi and built environment is very important to manage taxi service and improve transportation system. The issue is addressed by capturing the influence of built environment on taxi ridership considering spatial and temporal non-stationarities. The grid cells are developed as analysis units and the global regression model is adopted for preliminary exploring. Then the GWR are implemented considering spatial heterogeneity and the GTWR is used to analyze the spatiotemporal influence of built environment on taxi ridership. An empirical study conducted in Hong Kong Island using one-week taxi’s GPS data demonstrates the effectiveness of the regression models. It’s verified that GWR performs better than OLS, and GTWR outperforms the rest two regression models, indicating both time and space are critical dimensions.","PeriodicalId":32747,"journal":{"name":"Put i Saobracaj","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69273200","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}

Amendments to the \"Road Traffic Safety Act\" of 2009, for the first time in domestic regulations, defined the term \"School Zone\", which created the legal basis and precondition for a more serious analysis of problems in the defined zones. Despite these significant shifts in regulation, problems of continuous operation are still pervasive. Determining the actual cause of traffic accidents in the “School Zones” and implementing adequate measures is lacking and most often comes down to the implementation of a universal set of measures without a more detailed analysis of specific locations. This paper analyzes traffic accidents that occurred in elementary “School Zones” in the city of Belgrade in 2018, with the aim of determining the potential dependence of street network characteristics and traffic accidents. The analysis was conducted for previously defined network attributes in the school environment: number of streets, traffic category, traffic groups and network type, on the basis of which the mentioned dependence was examined. The research results are presented and discussed in the paper.","PeriodicalId":32747,"journal":{"name":"Put i Saobracaj","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69273656","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}
