Despite the generally positive impacts of these initiatives, the absence of robust causal evidence on their benefits can pose serious challenges for future investments in light of the existing social dynamic favoring the use of automobiles. Driven by the need to reduce motorized transport in Brazilian cities, we investigate the causal effects of bicycle routes on ridership between 2007 and 2017, focusing on travellers highly exposed to bike routes developed between 2008 and 2015. Using Difference-in-Differences models alongside Household Travel Surveys conducted before and after the interventions, we observed a modest but positive increase in cycling mode choice probability, ranging from 0.60 % to 1.37 %, among the highly exposed treatment groups. Our findings provide policymakers with valuable insights to support future cycling infrastructure planning and investment, demonstrating their potential net benefits even in car-dependent urban areas. By integrating these results into existing economic appraisal tools, policymakers can further assess additional benefits related to physical activity, health, and emissions reduction.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100021"},"PeriodicalIF":0.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950024924000131/pdfft?md5=dfbb022c31da06cc409f94041e536b21&pid=1-s2.0-S2950024924000131-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142150242","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}

However, models found so far overlook important features of crime data: spatial dependence and spatial heterogeneity. In addition, crime predictor data has shown to be multicollinear in previous studies. To tackle these issues, this paper analyzes mobile phone thefts and robberies at 19,329 bus stops in São Paulo (Brazil) based on Geographically Weighted Regression (GWR), using components retained from a Principal Component Analysis (PCA) as explanatory variables. A comparison is carried out between GWR and a non-spatial Transformed Linear Regression (TLR), and a Negative Binomial Regression (NBR) with uncorrelated predictors. Effects on crime from 9 PCs, representing central areas, bus transit level of service, transport infrastructure, land use and sociodemographic features, were proven to have high spatial variability. Changes in the surrounding environment can cause higher or lower increases in mobile phone thefts and robberies at stops according to their spatial location. Results showed that GWR performs better than NBR and TLR in predicting bus stop crime, thus compensating for a loss of information associated with PCA. In addition, GWR was able to completely incorporate the spatial dependence found in the non-spatial model, which covered the nearest 96 neighboring stops. The proposed method can effectively detect critical bus stops and regions, contributing to crime prevention. GWR coupled with PCA can also help identify the best locations to install new bus stops.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100020"},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295002492400012X/pdfft?md5=bc5779f3dfa8bfa7b3ea10dfd681e703&pid=1-s2.0-S295002492400012X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142095582","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}

Given the significance of Itapoá Port, which ranks fifth in containerized cargo handling, and the city of Joinville, known for its substantial cargo movement through the Port, this study focuses on the intricate dynamics of the maritime supply chain in this region.

The proposed framework demonstrates both operational and economic viability and emerges as a competitive option, yielding a 2 % reduction in costs for end customers compared to the current scenario. The results indicate a positive impact on the level of service offered to customers in Joinville, with a notable 65 % reduction in truck dwell time. Additionally, this approach fosters a more environmentally sustainable operation, achieving a 65 % decrease in greenhouse gas emissions.

Extensive research has scrutinized various transportation modes individually, yet a holistic assessment encompassing all modes while considering CO2 emissions needs to be more conspicuously present. Our study employs Data Envelopment Analysis (DEA) to evaluate the efficacy of transportation policies in South American nations in the context of United Nations-established sustainable development goals. Our overarching objective is to classify the sustainability status of South American countries' transport sectors and to establish benchmark models rooted in the six dimensions of sustainability. Methodologically, our analysis integrates operational transportation metrics, Gross Domestic Product per capita, Human Development Index, and CO2 emissions from transportation systems. Additionally, we draw comparative insights by juxtaposing South American countries against the G8 and BRICS nations. The rigorous application of DEA coupled with bootstrap validation fortifies the reliability of our findings. Our results bring to light these findings, positioning South American countries closer to their developed counterparts. Notably, the sustainable development models of Chile and Uruguay emerge as prominent exemplars. This study underscores the pressing demand for holistic and integrated development strategies to attain more sustainable outcomes across South American nations in a faster way. In conclusion, our research fills a conspicuous void in the extant literature by furnishing a comprehensive evaluation of transportation policy performance in South America.
