Adequate operational quality requires a certain level of robustness to delays and disruptions, but on segments with confined capacity, robustness becomes more fragile with increased traffic demand and speed heterogeneity. This trade-off between capacity utilization and service robustness predominantly manifests itself by compromising the reliability of rail freight services for two main reasons. Firstly, passenger trains are often prioritized in dispatching over freight trains. Secondly, many freight trains operate over longer distances and they accumulate more delays. Decreasing speed heterogeneity in mixed traffic may become pivotal in the interplay between robustness and capacity utilization. In this paper, we investigate possible improvements in capacity utilization and in railway service quality when introducing faster freight trains in mixed-traffic operations. The analysis is carried out on the Swedish Southern Main Line, which forms part of the Scandinavian–Mediterranean freight corridor. Microscopic simulation is used to explore performance indicators, such as simulated running times with respect to scheduled running times, capacity utilization, and punctuality, by implementing and comparing scenarios with different maximum speeds for freight trains. The results suggest that increasing the top speed of freight trains might seem as a promising approach for reduced utilization of capacity in the planning stage, but the stochasticity of operations in mixed traffic may become more challenging for delay recovery.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, current methods to enhance or create digital road networks are not well-adapted to regions with sparse geospatial data, often resulting in poor digital representations of road networks in less-developed regions such as rural areas of developing countries. We present a novel projection-based incremental insertion method that is well-suited to either enhance large existing road networks or combine multiple sources of road networks in regions with sparse geospatial data. In collaboration with PemPem and the World Bank, we perform two case studies that demonstrate the effectiveness of the proposed method. Together with PemPem, we show that our method significantly improves the digital road network for smallholder farmers in Indonesia, where only 40% of the origin–destination pairs in our dataset were previously digitized.

The paper moves from an existing framework, identifying the factors of fare evasion and risk exposure in terms of frequency (or probability) and severity (or vulnerability), and adopts Artificial Neural Networks (ANNs) to shed light on the intricate nexus between these components, estimating the fare evasion risk for every (segment of a) route. Next, the risk index is evaluated for each time period of interest. The predictions are ranked and represented by time-dependent dashboards to recognize routes with high-risk evasion that require deterrence strategies. Some real-time strategies are simulated from fare inspection logs, passenger surveys, and probability distributions on data collected in three years.

Moreover, different types of flooding have significant impacts on the transportation network and infrastructure including flash, riverine, urban, coastal, and storm surge. The variety of flooding scenarios makes it challenging to quantify the impacts of flooding on transportation across spatial scales; however, such metrics would be beneficial both prior to and after the event. Pre-flood metrics can promote enhanced impact-based decision-support guidance and hazard communication, while post-flood metrics may include larger regional disruptions located away from the most inundated areas and their associated secondary societal impacts. This study developed a retrospective Roadway Flood-Severity Index (RFSI) from 1982 to 2020 capable of integrating geo-located hydrometeorological data and transportation mobility information across localized and multi-state, sub-national regions to (1) categorize larger-scale, flood-related transportation disruptions, (2) understand the origins of those disruptions, and (3) identify severity risk levels of individual road segments and broader regions of transportation disruption during flood events. The fundamental question is, as flooding events unfold, can past hydrometeorological inundation information be coupled with transportation system network and mobility data to identify the most vulnerable roadway segments and regions? The overall mobility impacts of flooding on transportation were highly variable and relatively uncommon throughout the study period. Given this variability in other mobility data (e.g., vehicle speeds), hydrometeorological parameters were used exclusively as model inputs and crowdsourced Waze flood reports were used as the target response variable. A logistic regression based RFSI was found to best align with the dataset providing a “no flood” or “flood” classification. Eventually, this retrospective analysis will be extended to provide predictive capability as well. The RFSI is intended to provide transportation agencies with a quantitative metric to classify, categorize, and communicate the potential impacts of flood events throughout the transportation network.</p></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590198224002045/pdfft?md5=f94ec1e7f70aa968489d4706de7a4f1b&pid=1-s2.0-S2590198224002045-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
