Due to their lightweight nature, cost-effectiveness, and biodegradability, polylactic acid (PLA)-based materials are gaining attention in various transportation sectors, particularly in automotive and railway applications. PLA is commonly used in interior components and lightweight structural elements. However, defects such as voids, porosity, and layer delaminations may occur during the manufacturing process of this material, potentially compromising the material’s mechanical integrity and long-term performance. Infrared non-destructive testing (IRNDT) provides a fast and non-invasive solution for detecting such defects in PLA-based structures.

Strong connectivity, especially during disruption periods, significantly reduces passenger delays and potential revenue losses. Tackling these challenges demands coordinated disruption management strategies. To that end, we model coordination in a system comprising two traffic orchestrators, each responsible for managing their respective domains: airside and landside. The airside orchestrator can implement tactical flight delays, while the landside orchestrator can apply rerouting to assist passengers at-risk of missing their flights. Through negotiation between these orchestrators, the approach aims to minimize missed flights and passenger delays, while also exploring a fair distribution of costs. The negotiation process is structured using a game-theoretic framework, and an agent-based simulation is used to evaluate the effects on airport operations. A case study demonstrates the effectiveness of these measures in enhancing airport operations while balancing costs.</div></div>","PeriodicalId":101261,"journal":{"name":"Transportation Research Procedia","volume":"95 ","pages":"Pages 520-527"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147551833","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}

However, in many urban areas, high car usage leads to negative externalities such as congestion, pollution, and inefficient land use.

We address this problem using a bi-level programming framework as parking capacity decisions (upper level) influence driver route and parking choices (lower level), which in turn affect the objective values. Our main methodological contribution lies in enhancing the upper level optimisation through a novel mutation operator, which helps achieve lower objective values.</div><div>We apply our model to the city of Delft, the Netherlands, demonstrating that a diverse set of solutions with low objective values can be obtained.

It is focusing on three regulatory scopes: full coverage of all flights including those in and out of the EEA (European Economic Area), a reduced scope limited to intra-European routes and a departure-allocation scope covering outbound flights only. Ticket price adjustments are analyzed using pre-calculated trajectory optimizations that account for varying weather conditions, particularly regarding the formation of contrails. Contrail-induced cloudiness significantly enhances non-CO<sub>2</sub> climate effects increasing costs to different extents depending on the geographical scope of the regulation. Based on these cost increases, demand changes are assessed through passenger preference models that incorporate intra-market dynamics, capturing the competitive and behavioral responses of passengers across different market segments. This analysis provides valuable insights into the interplay between environmental policy and market behavior. It particularly includes mitigation strategies for non-CO<sub>2</sub> impacts, airline pricing strategies, and passenger behavior, offering guidance for the design of effective and equitable climate mitigation measures in aviation by quantifying the demand and network effect of these measures.</div></div>","PeriodicalId":101261,"journal":{"name":"Transportation Research Procedia","volume":"95 ","pages":"Pages 305-312"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147551899","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}
