Abstract Efficient and environmentally friendly public transport is a requirement of a modern city. For many years, Krakow has been building a modern multimodal transportation system, with the bus services playing a significant role. The article presents the results of the studies carried out on the fleet of urban buses operating within the Krakow agglomeration in the years 2010-2015. The influence of modernization of the urban bus fleet in the specified period on emissions of the most significant air pollutants into the air was evaluated. The studies have confirmed a total reduction in emissions from buses during the study period at levels of approximately 28 % for NOx, approximately 35 % for PM10, approximately 39 % for PM2.5 and approximately 43 % for NMVOC.

The coordination planning between land use and transportation system is an important premise of solving urban transportation problems and realizing land use integration. This study investigates the interactive and feedback relationship between land use and transportation system from the perspective of access management. By integrating the land use and traffic data from Las Vegas Metropolitan area with the system dynamics model, the causal relationship and causal loop diagrams (CLDs) are introduced to analyze the cause-and-effect relationship and quantitative relationship between the factors of the combined system of land use and transportation, and then sub-models partition and system simulation are performed. The systems dynamics model is established by analyzing the relationship between a series of access management techniques, traffic characteristics, and land use features. The results show that system dynamics model can be used as an effective alternative to model the symbiosis relationship of land use and transportation system for urban planning and construction.

According to the establishment of the simulation model about urban integrated transportation system, this paper established kinematics model of the urban integrated transportation system by the core application of system dynamics theory, technical methods and special tools. This model provided a scientific basis and technical methods to intelligent control and Optimizing the decision-making for urban integrated transportation.

Purpose This paper aims to understand the trade transportation situation between China and Koreas, and to explore the possibility of establishing the surface transportation corridor between China and Koreas in the future. Moreover, the paper also intends to find out the mode choice behaviors of shippers, which can be used to analyze the substitute effects of the surface modes on the water one. Design/methodology/approach The paper first analyzes the Sino-Korean bilateral trade and the corresponding trade transportation between China and Koreas. Secondly, it presents the surface transportation network between China and Koreas, and analyzes the warming relations between the North and South. Finally, the modal split of trade transportation between China and Koreas is estimated by establishing a mode choice model based on a questionnaire survey. Findings With the increasingly stable political environment and the physical highway and railway connections, the surface transportation network would become possible. Moreover, the shippers need the multimodal transportation system between China and Koreas, and many shippers would select road or rail mode if a suitable road or rail network were available. Especially, between China and South Korea, the road, rail and water mode may be used evenly, while the road mode may play a more important role between China and North Korea. The surface modes would have a huge substitute effect on the water mode. Originality/value The existing literature conducted research mainly from the perspective of economy and geopolitics, while the topics of transportation between China and Koreas are rarely concerned. This paper intends to throw some light on the situation of the trade transportation between China and Koreas, consider the potential of relation improvement on the Korean Peninsula proactively and study the surface transportation issues between China and Koreas.
