In many developing cities, the improvement of transport infrastructure is usually accompanied by major road construction and maintenance. This paper presents approaches and opportunities using peer-to-peer updating to improve spatial road networks undergoing construction and maintenance, which in turn will improve traffic flow and benefit cities overall. In many cities, the spatial road network requires maintenance, and these works often require traffic detours. With the current GPS (Global Positioning System) services, there is a noticeable delay in the updating of many spatial road networks. Thus, when a driver plans a trip to a certain location (such as Starbucks), his/her usual route may have changed, but the spatial road network in the GPS has not been updated. This can affect the user in many ways. For example, a trip that usually takes five minutes might now take half an hour, taking into account the additional time required to find alternative roads and possibly encountering more unexpected road closures, until the driver reaches his/her destination. This paper addresses this issue by proposing solutions that offer several advantages including a new peer-to-peer updating mechanism that helps to direct the driver to another route when road changes occur. Moreover, the peer-to-peer updating mechanism can enable the independent monitoring of road conditions and the updating of maps for newly-constructed roads, as well as the analysis of road congestions, traffic density, and people movements at certain times. Note that this work focuses on the conceptual ideas and approaches intended to improve independent maps, and the detailed algorithms have been left for future work.

空间路网的独立地图增强功能：基本应用和机会

在许多发展中城市，交通基础设施的改善通常伴随着重大的道路建设和维护。本文介绍了使用点对点更新来改善正在建设和维护中的空间道路网络的方法和机遇，这反过来将改善交通流量并整体上使城市受益。在许多城市，空间道路网需要维护，而这些工作通常需要绕行交通。使用当前的GPS（全球定位系统）服务，许多空间道路网络的更新存在明显的延迟。因此，当驾驶员计划前往某个位置（例如星巴克）时，他/她的惯用路线可能已更改，但GPS中的空间道路网尚未更新。这会在很多方面影响用户。例如，考虑到寻找替代道路所需的额外时间，并可能遇到更多意想不到的道路封闭，直到驾驶员到达目的地，通常需要五分钟的旅程现在可能需要半小时。本文通过提出具有多个优点的解决方案来解决此问题，其中包括一种新的对等更新机制，该机制可在发生道路变化时帮助将驾驶员引导到另一条路线。此外，点对点更新机制可以实现对道路状况的独立监视和对新建道路的地图更新，以及在特定时间分析道路拥堵，交通密度和人员流动。请注意，这项工作侧重于旨在改善独立地图的概念和方法，
