The W-PSS stands out for its approach that develops a new walkability index, underscores pertinent explanatory variables, and introduces a methodology for sculpting diverse walkability scenarios using the Multiscale Geographical Weighted Regression model which achieved an adjusted R-squared of 67.3%. Central to the findings is the significant role of employment density in enhancing walkability, and the nuanced interplay between commercial and population densities. A particularly insightful revelation is the unexpected negative correlation between cycling and walkability, emphasizing the need for a meticulous strategy to avoid cyclist-pedestrian conflict by harmoniously integrating and balancing both modes. Additionally, while cities with robust public transit showed limited room for enhancement, safety, and green space emerged as opportunities for refinement. Conclusively, informed by these insights, this research furnishes tailored scenarios and policy recommendations to foster enhanced walkability in urban landscapes. While the W-PSS framework offers a universal planning support system model for assessing and improving walkability, the study acknowledges that the concluded insights and implications vary based on each city's unique characteristics. Therefore, the application and the interpretation of results should be tailored.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"34 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139054741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated passenger touching behaviour within metro vehicles to understand the fomite exposure of passengers. Using in-vehicle CCTV on three lines of the London Underground, this paper investigated the number of touches on different types of train interiors and investigated their relationship with passenger density and movement. In total, 1,818 station sections and 16,891 passengers were observed cumulatively from May to December 2021. The results showed that on average for each type of interiors on Victoria and Jubilee lines, there were between 0.07 to 0.57 touches per passenger movement (i.e. boarding or alighting) for deep tube lines, whilst District line that uses larger carriages showed a different tendency. The results also suggested that for deep tube lines, the number of touches per person increased beyond a density of around 1.5 standing passengers per square meter possibly because passengers may touch interiors more in order not to bump into other passengers. These findings can be used in infection risk modelling and can inform mitigation of infection risk of future pandemics.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"25 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138744638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poor households living within low-income urban communities are disproportionately affected by these problems. This article reports an investigation of coping strategies among residents in a low-income community within Lagos, Nigeria. The study utilized a mixed-method approach – community survey (sample size = 300 residents) and semi-structured interviews with 15 purposively selected residents. The survey data was analysed statistically, while content analysis was conducted on the interview transcripts. The findings indicate range of personal/behavioural preventive and reactive strategies and building-related measures utilized to address the challenge of increasing heat within the community. Notably, greening-related practices (for planting trees, cultivating gardens) did not rank high among the residents. They are willing to pay modest amount towards greening and environmental features but not as much as housing modifications to enhance thermal comfort in the face extreme heat. The study contributes evidence of local coping strategies for heat exposure among disadvantaged urban residents, providing a pedestal on which heat adaptation initiatives can be developed.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"79 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138744713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Global warming increases the likelihood of a shift towards more warm days and seasons and fewer cold days and seasons. Additionally, it causes changes in precipitation patterns. In earlier research, as ambient temperatures increase, cognitive performance decreases and the risk of crashing increases. Earlier, crash-frequency models were developed using various methodologies, but time-series crash-frequency prediction studies considering the effects of climate change are scarce. Therefore, the purpose of this study is to identify the correlation between crashes and climate change using big data and to develop crash-frequency models using an econometric model and a deep-learning model. Econometric models use autoregressive-integrated moving average and autoregressive-integrated moving average with exogenous variable that are traditional time-series methodologies. Deep-learning models use long short-term memory. This study approached crash occurrence by comprehensively considering climate change and traffic factors. Also, it differs from earlier studies in detailing the influence of independent variables on crashes. Through the results, the impact of climate change on accidents can be identified and it can contribute as an engineering basis for improving traffic safety.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"42 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135944291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding and monitoring such changes are critical for the better management and design of public open space in case of future outbreaks of infectious diseases. To fill this gap, pedestrian movements are tracked and analysed with deep learning-based video analytics based on anonymized video footage along a major promenade in Hong Kong before and during COVID-19. Specifically, comparisons were made on pedestrian flow characteristics, pedestrian activities, and social distancing. Then, this study examines the dynamics of pedestrian crowding under different scenarios, using agent-based simulation. Model results suggest that the public space was characterized by fewer visitors, a higher average walking speed, a higher percentage of people exercising, and a lower percentage of people conducting stationary activities during COVID-19. In addition, a higher level of voluntary social distancing was observed. Several hotspots for pedestrian crowding were also identified. Learning from the above, it is suggested that multifunctional public space should be designed; and data-driven visitor management systems should be established to prepare for different scenarios in future cities.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"2 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76016215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of technologies, such as remote monitoring and telemetry, are being used to improve the quality of asphalt materials during the construction phase. Based on real-time data, the movement and arrival of delivery vehicles can be monitored and material temperatures can be recorded at each stage of the paving process. Similarly, roller compactor passes can be mapped to show the number of passes, compaction temperature and area of mat covered. Importantly, the technology has the capacity to create a safer working environment for road workers. This paper describes a study that builds on previous work, with the aim of developing notes for guidance and compliance requirements for electronic data monitoring. A series of criteria are proposed to approve the level of compaction based on electronic data. The latter includes the adoption of a similar approach to that being used in the USA, although certain aspects have been adapted for the type of materials and equipment available in Scotland. It is intended that the compliance requirements will be trialled on forthcoming paving schemes to determine their effectiveness and whether further amendments are required.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"42 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74428382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A one-way analysis of variance is performed to analyse the influencing factors of subway use of senior and non-senior passengers during the COVID-19 pandemic. Furthermore, a multiple linear regression is conducted to identify the factors affecting senior and non-senior passengers. Finally, the traffic patterns of senior and non-senior passengers were analysed with respect to districts via geographically weighted regression. The spatial scope of this study includes Seoul, which consists of 25 districts (gu). The temporal range is from 1 January 2017 to 31 December 2020, and the number of people using subway in Seoul is used as the main dataset. The results suggest that senior passengers are more affected by subway than non-senior passengers, and the most influential factors are cultural gathering facilities and the number of subway stations. The regression model showed high explanatory power for southern Seoul, which has a high concentration of facilities related to the influencing factors.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"31 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86670596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to its peculiar topographic structure, the history of the city – from its foundation to the present day – has led to unique and contradictory characteristics. A multipurpose land cadastre (MLC, in Portuguese: Cadastro Técnico Multifinalitário), since its inception in Brazil, promises to adapt urban environments to a new reality, facilitating the management of their entire territories by using tools such as geographic information systems. This study intends to identify and analyse the main issues that prevent Rio de Janeiro from establishing an effective MLC, most notably the existence of a variety of land-use bases with legal value, but which are contradictory if examined cartographically. This study was carried out by examining a subset of Rio de Janeiro: the Bangu neighbourhood. Bangu was chosen for being a considerably complex neighbourhood, with a variety of land uses that reflects the urban fabric of Rio de Janeiro as a whole. The analysis not only points out inconsistencies in current cadastral bases, but also suggests tasks and policies to help overcome them and provide the city with appropriate cadastral bases that reflect the reality of its urban soil.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"59 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84323962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The status of physical access to educational institutes in the region is determined by the collective characteristics of the area, such as proximity and the level of services available. Transport accessibility in rural areas is challenging and affects the physical access to education in developing countries. Subsequently, a research enquiry is posed: does transport accessibility in the region affects access to educational opportunities in the rural context? If yes, what transport-related determinants influence access to educational opportunities? Census data is used for analysis, employing a multivariate regression approach using ordinary least squares estimation. The key revelations of the research are (a) proximity to the educational institute and transit are the critical determinants of attending the educational institute in rural India, (b) bicycle ownership improves attendance at educational institutes in the study region and (c) a considerable gender differential and the rural–urban gap in attending the higher educational institutes exist, signifying the accessibility poverty in the region.

The documented studies identify various barriers and solutions for PBSS but study on identification of optimum solution for varied conditions is limited. Therefore, the purpose of this study is to rank the barriers and solutions for PBSS implementation for Indian urban areas. As the framework is robust so methodology can apply globally. Initially, 31 PBSS barriers and 14 solutions were identified after reviewing literature and assessment from professionals. Finally, two Multi-Criteria Decision-Making methods (MCDM) were integrated to rank barriers and solutions for Indian cities using an expert opinion survey. The result shows that infrastructure barriers of the city, social barrier for cycling and travel characteristics barriers have more impact in the main criteria whereas presence of exclusive bicycle lane, government policies and provision of modified and e-bicycle are found to be the most optimum solutions and have potential to overcome the influence of barriers. The outcome of this research will help various stakeholders to develop pro-cycling policies, decision on financial resource allocation, understanding on the existing barriers and solutions to develop future policy to increase PBSS usage.","PeriodicalId":54571,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Municipal Engineer","volume":"90 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80296628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
