Managing waste is a crucial challenge for modern societies. The UK government has established ambitious targets in terms of landfill diversion for household waste. Household Waste Recycling Centres represent key facilities for achieving these targets. However, Local Authority budgets are under severe strain due to reductions in central government transfers. As such, local councils often need to perform reconfigurations of the recycling centres networks, by reducing the number of sites or their opening hours while still offering adequate service levels. Central to being able to do this, is understanding the spatial patterns of access to such centres. Therefore, this paper develops a spatial interaction model aimed at examining and exploring users’ behaviour and preferences when choosing recycling centres. Specifically, an origin-constrained gravity model is developed; through a careful estimation of its attractiveness parameters, the model is capable of describing demand flows from Sheffield City Council districts to Household Waste Recycling Facilities. The results are compared to actual data obtained through a users’ survey from an English Local Authority. The high level of correlation between the results provided by the model and actual users’ preferences indicates that the model can be a valuable tool in describing users’ behaviour in accessing the service. Based on this, the model can be employed in order to estimate the impacts of modifications to the network configuration on users, performing scenario analyses and providing useful suggestions to planners.

一种空间交互模型,用于表示用户访问生活垃圾回收中心

对于现代社会而言,管理废物是一项至关重要的挑战。英国政府已经建立了针对生活垃圾的垃圾掩埋转移的雄心勃勃的目标。家庭废物回收中心是实现这些目标的关键设施。但是,由于中央政府转移支付的减少,地方政府的预算承受着巨大的压力。因此,地方议会经常需要通过减少站点数量或开放时间来重新配置回收中心网络,同时仍要提供足够的服务水平。能够做到这一点的核心是了解进入这些中心的空间模式。因此,本文开发了一种空间交互模型,旨在检查和探索用户在选择回收中心时的行为和偏好。特别,建立了原点约束重力模型;通过仔细评估其吸引力参数,该模型能够描述从谢菲尔德市议会辖区到生活垃圾回收设施的需求流。将结果与通过用户调查从英国地方当局获得的实际数据进行比较。该模型提供的结果与实际用户的偏好之间的高度相关性表明,该模型可以是描述用户访问服务行为的有价值的工具。基于此,可以使用该模型来估计对网络配置的修改对用户的影响,执行方案分析并为计划者提供有用的建议。该模型能够描述从谢菲尔德市议会辖区到生活垃圾回收设施的需求流。将结果与通过用户调查从英国地方当局获得的实际数据进行比较。该模型提供的结果与实际用户的偏好之间的高度相关性表明,该模型可以是描述用户访问服务行为的有价值的工具。基于此,可以使用该模型来估计对网络配置的修改对用户的影响,执行方案分析并为计划者提供有用的建议。该模型能够描述从谢菲尔德市议会辖区到生活垃圾回收设施的需求流。将结果与通过用户调查从英国地方当局获得的实际数据进行比较。该模型提供的结果与实际用户的偏好之间的高度相关性表明,该模型可以是描述用户访问服务行为的有价值的工具。基于此,可以使用该模型来估计对网络配置的修改对用户的影响,执行方案分析并为计划者提供有用的建议。该模型提供的结果与实际用户的偏好之间的高度相关性表明,该模型可以是描述用户访问服务行为的有价值的工具。基于此,可以使用该模型来估计对网络配置的修改对用户的影响,执行方案分析并为计划者提供有用的建议。该模型提供的结果与实际用户的偏好之间的高度相关性表明,该模型可以是描述用户访问服务行为的有价值的工具。基于此,可以使用该模型来估计对网络配置的修改对用户的影响,执行方案分析并为计划者提供有用的建议。
