“…Referring to Li and Wang [22] definition, since fuel costs are an important determinant of the cost of transport services, rising fuel prices may be one of the reasons for the growth of road transport costs. A reduction in transport costs can be caused by lower fuel costs, but it can also be caused by competition in the transport market.…”

This study is aimed at evaluating the functionality of urban transport terminals in Elbasan City, identifying potential shortcomings in their modernization process, and providing actionable recommendations to enhance the quality of urban transit services. The study also investigates the challenges and impacts associated with transitioning from private vehicles to urban public transport systems within the city. Various research methods, including analytical, classification, functional, and statistical approaches, were employed. The research scrutinizes the unique aspects of the city's urban functioning and pinpoints the errors made during terminal modernization, further exploring their underlying causes. It also examined strategies to improve transport mobility. Analyzing the system's operation is crucial to understanding its effectiveness, growth, and the complexities associated with the shift from private cars to urban public transport in Elbasan. This research also evaluates urban transport terminal-related concerns, their importance in the context of urban transport, and their implications. Based on the findings, recommendations were proposed to address these concerns. The study's findings underscore the importance of enhancing urban public transport. It highlights that boosting the transportation potential is not only crucial for meeting the community's transportation needs but also plays a pivotal role in advancing logistics.

“…According to the International Energy Agency, in 2018, emissions from transportation constituted a 25% of global emissions [1]. Without effective interventions, projections suggest this figure could escalate to 30% by 2030 and 50% by 2050 [2]. Notably, despite road transport representing over 70% of total transportation, its carbon intensity exceeds that of rail transport by fourfold and that of inland waterway transport by tenfold [2].…”

This study aims to enhance multimodal transportation systems by mitigating CO2 emissions and enhancing operational efficiency. It introduces a novel centralized cargo concentration approach tailored for regions facing geographical challenges. The method proposes for direct transportation of cargo from its loading origin to export ports, bypassing intermediate hubs. The mathematical model determines the most efficient means of transport for each route, factoring in variables like distance, volume, and cargo type. Research results indicate that, in scenarios with a high concentration of cargo, multiple hubs may not be necessary, which could streamline transportation and logistics operations. Modal preferences vary based on regional dynamics and cargo characteristics, with rail and sea transport emerging as preferable options under specific circumstances, surpassing the efficacy of road transport. The proposed model showcases reductions in both logistics costs and CO2 emissions compared to road-centric scenarios. It underscores the strategic integration of diverse transportation modes as pivotal for enhancing efficiency and sustainability. This study furnishes a framework adaptable to optimizing multimodal transportation systems in regions sharing similar geographical and logistical attributes.

“…More than 75% of the population will live in urban areas by 2050 [1], and it is estimated that traffic flows will reach about 64% of all travel made around the world [2]. Moreover, the emissions from the transportation sector are expected to account for almost 50% of global emissions by 2050, if no key measures are undertaken [3]. Therefore, achieving more efficient and low-carbon mobility is crucial in ensuring urban systems are sustainable [2].…”

Creating new multimodal infrastructure in an existing transport network of an urban city is a challenging process. The responsible transport authorities have to pay special attention to the details regarding the accessibility and effectiveness of the new development, to avoid travelers’ confusion and network congestion. The subject of this paper is the assessment and optimization of the traffic network in the surroundings of the new multimodal depot of Thessaloniki’s future metro system with the use of the microsimulation software PTV VISSIM (version 2022). Five different scenarios were developed in collaboration with the city’s transport authority and evaluated into two stages, beginning with the whole traffic network, and then continuing with the analyzed intersections separately. The evaluation is based on Key Performance Indicators (KPIs), which were extracted by the software. According to the results of the base case scenario, the network functions satisfactorily, with slight delays. Regarding the future network, the operation of the new hub will strongly increase the traffic demand, while the proposed traffic network adjustments by the local authorities seem to cause significant delay problems. This paper aims to highlight the importance of using modeling tools during the design phase of a new infrastructure to create efficient, accessible, and sustainable infrastructures that enhance the public transport system.
