Optimising Geofencing - Phase 2

该项目将优化排放地理围栏，使其比现有系统更加灵活，从而通过改善新巴士车队、插电式混合动力汽车和现有车辆的排放来提高新车的性能。车辆的位置可以用来改变它的行为。这项技术可用于减少特定地点的排放，例如城市中心，通常被称为地理围栏。地理围栏的使用需要车辆的准确位置，一种改变车辆行为的方法，以及定义地理围栏操作位置的规则。目前的系统最近被应用于公交车的运行，因为它们经常在市中心空气质量差的地区运行。最近，一些插电式混合动力车也引入了地理围栏，以鼓励它们只使用电动汽车，以改善空气质量。为了增加地理围栏的使用，从而改善整个英国的空气质量，该项目将展示更灵活的地理围栏架构的潜力。一方面，制定更加灵活的地理围栏规则——例如，允许地方当局或车队运营商根据路线拓扑、整体空气质量、交通水平或一天中的时间来改变区域的范围。另一方面，通过展示如何影响私人车辆的行为，以应对地理围栏，低排放区域，特别是如何确保不断增加的插电式汽车（phev）车队得到有效利用。最后，考虑到对空气质量的直接和间接影响，将使用相同的基础分析和开发方法来优化未来的移动即服务方案。这将使地方当局能够规划这种未来综合交通模式解决方案的推出，并有信心对其市民产生更广泛的影响。

This project will optimise emissions geofencing to be more flexible than current systems allowing them to enhance new vehicles performance by improving the emissions of new bus fleets, plug-in hybrid vehicles and existing vehicles in circulation today.The location of a vehicle can be used to change its behaviour. This technology can be used to reduce emissions in specific locations, for example city centres, and is often known as geofencing. The use of geofencing requires accurate location of the vehicle, a method to change the vehicle behaviour and rules to define the location where the geo-fence is operational.Current systems have been recently been applied to the operation of buses as they often operate in regions of poor air quality in city centres. Geofencing has also recently been introduced in some PHEVs to encourage their usage of electric only operation to improve air quality.To increase the uptake of geofencing and thus improve the air quality across the UK, this project will demonstrate the potential of more flexible geofencing architectures. On the one hand, making the rules that define the geofence more flexible - for example by allowing the local authority or fleet operator to vary the extent of the zone as a function of route topology, overall air quality, traffic level or time of day. And on the other hand, by demonstrating ways to influence the behaviour of private vehicles to respond to geofenced, low emission zones and in particular, ways to ensure the increasing fleet of plug in vehicles (PHEVs) are used effectively.Finally, the same underlying analysis and development approaches will be used to optimise future Mobility as a Service scenarios, considering both the direct and indirect impacts on air quality. This will enable local authorities to plan for the roll-out of such future integrated transport mode solutions with confidence in the wider impacts to their citizens.
