National Freight Model (Phase 2)

英国的货运系统是广泛的，包括约195，000家企业，250万名员工，并为经济贡献了1210亿英镑的总附加值（GVA）。在大多数地方，轻型货车和重型货车贡献了约30%的运输碳排放。英国最近的每一项主要研究都指出了货运方面的重大数据局限性，NIC得出结论认为，因此，规划系统中存在“货运盲目性”。作为目前效率低下的一个明显症状，据认为，英国道路上约30%的英国注册HGV是“空跑”。这导致了一系列问题，如不必要的成本、拥堵、额外的车辆里程和更高的排放。开发任何新的货运解决方案的第一步是在汇总和分解层面提供足够的数据。由于货运在商业上特别敏感，因此无法获得广泛的数据。然而，建模可以帮助填补这一空白。我们的项目填补了这一空白，将来自广泛来源的广泛地理空间数据和模型汇集到一个完全开放的国家货运模型中，供地方当局、顾问、政府和公众使用。该模型将被设计为可以通过广泛的类别来探索和分割路线/流量/拥堵，以帮助下游分析和应用。

The UK Freight system is extensive comprising around 195,000 enterprises, 2.5 million employees, and contributing £121 billion gross value added (GVA) to the economy. In most places, LGVs and HGVs contribute ~30% of transport carbon emssions. Every recent major UK study has noted the significant data limitations within freight with the NIC concluding that, as a result, there is "freight blindness" in the planning system. As a clear symptom of the current inefficiencies, it is thought that around 30% of UK registered HGVs on the UK's roads are "running empty". This is leading to a range of issues such as unnecessary costs, congestion, additional vehicle miles and higher emissions.The first step in developing any new freight solution is availability of adequate data at an aggregate and disaggregate level. Due to the particular commercial sensitivities of freight, wide-spread data is not available. However, modelling can help fill this gap. Our project fills this gap by bringing together extensive geospatial data and models from wide range of sources into a fully open National Freight Model available for use by local authorities, consultants, government and the public. The model will be designed such that route/volume/congestion can be explored and segmented through a wide range of categories to aid downstream analysis and application.
