Transport Scotland

In order to enhance the accuracy of thermal response estimation, this study proposes the utilization of a deep learning-driven method, specifically the Long Short-Term Memory (LSTM) network, for predicting temperature-induced strains and deflections in the Queensferry Crossing, UK. Initially, an examination of the temperature fields of the bridge is conducted based on monitored temperature data. Subsequently, the LSTM network is introduced as a tool to estimate thermal response utilizing temperature field information. The study proceeds to discuss the results of temperature-induced response estimation, including strains and deflections, obtained through the LSTM network, with a comparative analysis against a linear regression model. It is observed that the temperature discrepancies among steel components within the bridge are lesser in comparison to those of concrete components. The LSTM network exhibits higher estimation accuracy than the linear model, manifesting in an improvement of mean square error from 4.45 to 0.89 for strain estimation. In addition, the LSTM network can partially address time-lag effects. However, the estimation performance of the LSTM network is influenced by the structural response type and the resolution of employed sensors. Specifically, the correlation coefficient (R) associated with strain estimation is measured at 0.980 using the LSTM network, whereas R for deflection estimation stands at 0.825. Generally, local structural responses, such as strains, outperform global responses like deflections. Furthermore, sensors with higher resolutions yield enhanced estimation accuracy.

PurposeTo share learning from the application of a pragmatic, evidence-driven, systems-based approach to physical activity policy in Scotland at a national and local level from a sportscotland (national agency for sport) perspective.Developmentsportscotland invests in and work with all 32 local authorities and leisure trusts to deliver shared local and national outcomes and priorities for sport and physical activity.Working in partnership, sportscotland and Public Health Scotland are supporting local government partners apply the systems-based approach used nationally, to guide the development of local and regional evidence-based physical activity strategies and action plans.Implementation and disseminationLocal government in Scotland is made up of 32 local authorities which vary in size, demographics, and population. We are implementing the approach across a range of settings including Island, rural, city, and mixed urban/rural.Collectively we provide leadership and support to enable local partners at a local level to adopt a systems-based approach to physical activity to shape the local strategic direction of physical activity and sport.We provide support, guidance, and resources to local governance groups to help design and shape the local approach and co-facilitate workshops to engage key stakeholders from health, social care and, local government departments including sport and leisure, education, planning, place and transport.EvaluationEach local strategy and associated action plans identify local outcomes, outputs and indicators and local governance groups oversee implementation. Accountability and reporting arrangements vary and are aligned to local structures which include Community Planning Partnership.s, Health Boards and/or Council Committees.Conclusions and practical implicationsLocal implementation of the systems-based approach is critical to ensuring we reduce physical inactivity across Scotland.Successful application of the approach is dependent on local leadership, capacity, and commitment.Partners provide staff time within existing resources. Financial resources are limited across local government and health, the approach aims to maximise use of existing capital, revenue and human resource.

Area Manager,

A series of rainfall-induced debris flow events in August 2004 affected the Scottish road network, and at Glen Ogle 57 people were airlifted to safety. Although there were no major injuries, the social and economic impacts were significant, particularly the severance of access to and from relatively remote communities. A study was commissioned with the overall purpose of ensuring that the hazards posed by debris flows were systematically assessed and ranked, thus allowing actions at specific sites to be prioritised effectively within available budgets. The methodology used to undertake a pan-Scotland, GIS-based assessment of debris flow susceptibility is described, as is the approach taken to interpret the resulting imagery in order to establish those sections of road alignment subject to hazards. The hazard scores assigned using this approach were subsequently modified in the light of the results of site-specific inspections. The ranking of hazards based upon the potential exposure of road users to debris flow hazards and the potential socio-economic impacts is also described, and a map illustrates the locations of the highest hazard-ranking sites. The success of the system is briefly discussed in the context of subsequent events, and the approach to management and mitigation is outlined.
