However, most studies have overlooked the importance of bicycle parking facilities in the network-planning process. In this work we aim to draw attention to the importance of including bicycle parking (BP) facilities in a well-thought-out bicycle infrastructure planning process highlighting the detrimental effects of not doing so for transportation equity, using Bogotá, Colombia, as a case study, where bicycle trips have multiplied in the last few years, reaching a 6.6 % modal share in 2019. To this end, we present a geospatial analysis and machine learning approach to assess the network coverage of bicycle parking spots. Additionally, we compared the city's bicycle trip patterns and applied a survey to know the perception of users (n = 397). The results show that the current distribution of bicycle parking in the city does not favour equity, given that it is not in line with the origin and destination of bicycle trips. This could widen socio-territorial inequity by affecting accessibility to bicycle use for daily commutes. To the best of our knowledge, this study presents the first assessment of the impact of parking distribution on the planning of bicycle infrastructure in the Global South.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100022"},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950024924000143/pdfft?md5=2e4342629263e6d3c0b9cb5ac7578c1b&pid=1-s2.0-S2950024924000143-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142161596","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}

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}
