The most common measure for the implementation public transport priority in Russian Federation is the organization of dedicated lanes. Most often, lanes for public transport are created by reducing the number of lanes for cars and trucks. This method effectiveness is well studied, and it is also known that this measure leads to deterioration in traffic parameters for private vehicles. The article discusses an alternative variant of the public transport priority on intersections with the use of traffic light adaptive control. The analysis of the advantages and disadvantages of two algorithms for adaptive control of traffic light objects is carried out according to the criterion of reducing the delay time of public transport when driving through intersections. With the help of imitation micromodeling, the dependence the delay time on the traffic intensity at a separate intersection was established for the basic variant, the variant with a lane for public transport, two variants of the active priority and the combined variant “active + passive” priority. For all variants, a comparative assessment was made of the deterioration of the driving parameters for personal cars and the improvement for public transport. The methods of granting the public transport priority were ranked according to the criterion of efficiency (travel time delay) for vehicles and all transport system users (drivers and passengers). It was found that in terms of average user travel time delay, passive priority reduces delay by 11.2% on average across the board. Using the combined method (active + passive) reduces user travel time delay by 17.1%. Also, using the combined method reduces the negative effect on personal vehicles compared to passive ones.","PeriodicalId":259696,"journal":{"name":"Urban and Maritime Transport XXVII","volume":"102 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133203666","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}

With the nodes representing the entities of the system, and the links the relationships among them, CNA allows a topological characterisation of the system, assessing its structure. In recent years, researchers have shown an interest in modelling maritime traffic as a complex network, for analysing connections and relationships among different stakeholders. This paper proposes to model the maritime traffic flow of some food products, traded internationally. The model considers the traffic flows from Spain, allowing to group the partner countries whose traffic flow patterns are similar. These groups (communities), can help decision makers to identify their direct competitors and search for alliances or new markets comparing themselves with those ports that have similar infrastructures. The abovementioned procedure is applied to the export traffic of fruit, vegetables and legumes. Spain is the main fruit and vegetable producer in the EU, the first exporter in the EU and the third in the world. In the Spanish fruit and vegetable sector, part of the products are exported to the EU partly by land, but Spanish ports play a critical role in the transport of this type of goods. The importance of exports to other countries, which are mainly carried out by sea, makes it particularly interesting to study the role of Spanish ports in the export of this type of goods, and the possibilities of improving maritime traffic of these cargo for the Spanish port system. The conclusions derived from the analysis of the export connectivity of Spanish ports for the goods studied are presented, with some of the most important ports for these goods being geographically distant from the production areas, but with a high land connectivity with these regions.","PeriodicalId":259696,"journal":{"name":"Urban and Maritime Transport XXVII","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115318435","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}
